Operational Overview Power-up Sequence: Upon power-up, the controller checks the position of the Mode Select Switch. The controller initializes the OLED display or switch based on this selection. The proper selection of switch/display mode must be set before power up. The OLED switch will show the full image while the “Display” position will display only the middle 52 pixels of the top 36 lines of the image and the to 36 rows. OLED Brightness Adjustment Mode: There are 16 levels of brightness 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F where F is the maximum brightness. The level of brightness is displayed in the middle of image. After power-up, the display is at the maximum brightness (level F). The controller will allow the brightness of the two OLED modules to be adjusted. The left OLED displays the brightness level F and the word DIM. The right OLED displays the brightness F and the word BRIGHT. The left button can be pressed to make both displays dimmer and the right button makes both displays brighter. The OLED rated life of 50,000 hours is based on maximum brightness. The dimmer the level is set the longer the expected life of the OLED. Any switch activity will keep the unit in this mode. The brightness changes stay in effect for the duration of the session. After 2.6 seconds of user inactivity the controller will move into the main operations mode. Main Operational Mode: There are 65,535 addresses (0x0001 to 0xFFFF) to store images and attributes. Upon power-up, as default, OLED switch one displays the image of address 0x0001 and OLED switch two displays the image of address 0x0010. These addresses are user defined and can be changed. The attributes at the respective address become the active attributes for each switch. The controller then transmits 11H via USB indicating it is ready for operation. The images on the switches change based on: A. Attribute setting for switch presses B. Attribute setting for timers C. Commands via USB IS-Dev Kit-7 User Manual E.docx Toll Free 1.877.2BUYNKK (877.228.9655) • Phone 480.991.0942 • Fax 480.998.1435 www.nkkswitches.com • Email engineering@nkkswitches.com Page 6 of 51 1120 IS-DEV KIT-7 User Manual 7850 East Gelding Drive • Scottsdale, AZ 85260-3420 Flash Memory Organization The Flash memory can hold up to 65,535 images and attribute blocks (Addresses 0001H to FFFFH) for the Frameless OLED SmartSwitch. The images are pictures to be displayed. The attributes are user-defined information on what image is to display based on the switch activity and the timer expiration. The images and attributes need to be downloaded before operation. Address 0001 0002 ----FFFE FFFF OLED Switch Image Attribute Block Image Attribute Block Image Attribute Block Image Attribute Block Image Attribute Block Image Attribute Block The IS-DEV KIT-7/7D is programmed with factory default images. The user can change the images and programming through the use of attributes. The controller associates one address to each image and the display shows the image at the associated address. Each address has a group of five attributes which together is called an Attribute Block. The function of the Attribute Block is to tell the controller what image to display next, either when the switch associated with that particular address is pressed or when the timer expires. Address for Switch #1 0000 to FFFF Address for Switch #2 0000 to FFFF End of the Loop Address Timer #1 0000 to FFFF 00 to FF Timer #2 00 to FF Changes based on the OLED switch presses • When either switch number one or number two is pressed, the changes happen based on the active attributes for that switch. It can change the active address in one or both or neither of the switches. If the “Address for Switch #1” active attribute is equal to zero, there will be no change to switch one. Otherwise, switch number one displays the image at the address indicated in “Address for Switch #1” and the attribute of this address becomes active for switch number one. If the “Address for Switch #2” active attribute is equal to zero, there will be no change to switch two. Otherwise, switch number two displays the image at the address indicated in “Address for Switch #2” and the attribute of this address becomes active for the switch number two. • While either of the switches is pressed, the timer for that switch pauses, if the timer is running.

Therefore, there will be no change based on the timer for switch number one. Otherwise, the timers run and the images change sequentially from the original address (active address) to the address indicated by “End of the Loop Address”. The number of milliseconds (ms) each image is displayed is the product of Timer #1 multiplied by Timer #2. The maximum possible time is 65 seconds. The timer value in ms = (Timer #1) x (Timer #2), Note: if Timer #2 = 0 it counts as 256. The attributes of the original address (active address) stays in effect and the attributes of all other addresses are ignored until the end of the loop address is reached. • Once the end of the loop address is reached, the attributes of this address are checked (does not become active) and changes can happen based on these attributes as stated below: 1. If the “Address for Switch #2” of the end of the loop attributes is equal to zero, no change to switch number two. Otherwise, switch number two displays the image at the address of “Address for switch #2” and the attribute of this address becomes active for switch number two. 2. If the “Address for switch #1” of the end of the loop attributes is equal to zero, then switch number one loops back to the image of the original address (active address) and the loop starts over. Otherwise, switch number one displays the image at the address of “Address for switch #1” and the attribute of this address becomes active for the switch number one. • The switch number two attributes function in the same manner as described above for switch number one. Changes based on commands via USB There are many commands available to control the OLED switches. They are described in detail in section 7, The Communication Protocol. Below is the list of commands available during operation. • • • • • • • • • Command to reset the controller Command to check connection Command to change brightness of OLED switches Command to any of the OLED switches to display any address image Command to turn on any row of an OLED switch to any color Command to create up to 12 characters with any color from any location in an OLED switch Command to turn the display ON/OFF Command to write directly to OLEDs Command to disable/enable attributes execution based on timer and switch presses IS-Dev Kit-7 User Manual E.docx Toll Free 1.877.2BUYNKK (877.228.9655) • Phone 480.991.0942 • Fax 480.998.1435 www.nkkswitches.com • Email engineering@nkkswitches.com Page 8 of 51 1120 IS-DEV KIT-7 User Manual 7850 East Gelding Drive • Scottsdale, AZ 85260-3420 Report from Controller via USB The controller reports timer expirations, switch presses, switch releases and the address of a new image display if the appropriate bits in the set-up flags are enabled. • If the Bit 6 of the flag is enabled, the controller reports switch presses in one byte --- OLED Switch #1 81H --- OLED Switch #2 82H • If the Bit 3 of the flag is enabled, the controller reports switch releases in one byte --- OLED Switch #1 B1H --- OLED Switch #2 B2H • If the Bit 5 of the flag is enabled, the controller reports timer expirations in one byte --- OLED Switch #1 83H --- OLED Switch #2 84H • If the Bit 7 of the flag is enabled, the controller reports a leading byte followed by the address of any new image displayed for a total of 3 bytes.

Programming the IS-DEV KIT-7 using Universal Communicator 2015 The IS-DEV KIT-7/7D communicates via USB with any communication software. The commands and protocol will be explained in sections 6 and 7. This section covers programming the Dev Kit using the Universal Communicator 2015 without getting into technical details. Creating Images Images for the OLED switches can be created using any graphic software that can save a 24-bit color bitmap in a 64 x 48 format. When resizing pictures, the colors may become faded. The saturation, hue and brightness can be adjusted to improve the picture quality. There is documentation on creating images and videos in the “How to” section of this webpage: http://www.nkkswitches.com/SmartSwitch-Engineering-Documentation.aspx Naming Images The Universal Communicator 2015 loads the images in alphabetic order according to the image file names and displays the addresses that each image will have in the controller. Be sure to name images so the video images or loop images are listed sequentially. Avoid using symbols in the names as some symbols interfere with alphabetic ordering. It is not necessary to have all images in one folder as Universal Communicator 2015 allows for selecting a starting address for download. However, for making attributes, it is easier if all the images are in one folder so the image addresses in the controller can be checked in the Universal Controller. Downloading the Images to the Controller Start the Universal Communication 2015 software and follow the following steps: 1. Click “Import Files” and then navigate to the image folder and click “OPEN”. The images will load to the Universal Communicator. Notice the addresses next to the image names. These will be the image addresses in the controller. Clicking on any image name will display the image on the left of the screen. 2. Make sure the development kit is connected to a computer USB connection. 3. Select the serial communication port number to which the development kit is connected. 4. Select Baud Rate 57600. 5. Click the “Port Closed” button to open the communication. If the development kit has the factory default images and program, the controller will transmit information to the computer which will be displayed in IS-Dev Kit-7 User Manual E.docx Toll Free 1.877.2BUYNKK (877.228.9655) • Phone 480.991.0942 • Fax 480.998.1435 www.nkkswitches.com • Email engineering@nkkswitches.com Page 10 of 51 1120 IS-DEV KIT-7 User Manual 7850 East Gelding Drive • Scottsdale, AZ 85260-3420 green font. For example: “83” and “84” will be displayed. The addresses for the images are also displayed. 6. Click the “Call” button. The computer will send “01” in blue and the controller responds with “61” in green. This may not be seen if the controller is sending the timer expirations and addresses. However, if the controller does not send anything, there is likely a problem with the serial connection or set up. It should be fixed before proceeding. 7. Click “Download Batch”. The controller will respond with “6179” for each image downloaded. Every image takes 2.5 to 3.5 seconds to download. Universal Communication 2015 will display an error message if anything is wrong or notify when the download is complete. 8. Leave Universal Communication 2015 open in order to look up the image addresses for creating the attributes block which determine how the various images are displayed on the OLED switches.

There will be many rows of this command. The only fields you need to fill in are highlighted in green above. Set Up Command There are eight cells for setup command. Only the three cells highlighted in green should be changed. The other five cells must not be changed. 1. Flags: Do not change flags as it does not affect the stand-alone operation. 2. Start Address for Switch #1: Enter the address for the image you want to be displayed on the left switch (switch number one) after you turn on development kit. You can check Universal Communicator 2015 for the address of the image and type it in. The address 0001 has been entered in this template as an example. 3. Start Address for Switch #2: Enter the address for the image you want to be displayed on the right switch (switch number two) after you turn on development kit. You can check Universal Communicator 2015 for the address of the image and type it in. The address 0003 has been entered in this template as an example. Attribute Command Each image address can have an attribute block. However, it is not necessary to create an attribute block for each image address. There must be a minimum of two attribute blocks (One for switch one start up and one for switch two start up). The maximum number of attribute blocks is equal to the number of images. One row needs to be added for each attribute block. An attribute block needs to be created only for the active address and for the end of the loop address. The attribute blocks do not have to be in any particular order. If more than one attribute block is created for the same address, only the last one will be used. There are eight cells in each attribute block. Only the six cells highlighted in green should be changed. The first two cells must not be changed. Upon power-up, switches number one and two display the images at the start addresses from the setup command. The attributes for these addresses become active attributes for the two switches. Therefore, at minimum, attribute blocks need to be created for the two switches. Attribute blocks must be created for any new address the switches are to display due to switch presses or end of the loop jump. Only the first and last image address of videos or slide shows must have attribute blocks. There is no need to create attribute blocks for the middle images.

Address: This is the address of the attribute block associated to the image. The first two attribute blocks created are the startup addresses in the setup command. Type in the address. 2. Address for sw1: If the switch that has this attribute block as the active attribute is pressed, and the input address in this cell is not equal 0000, then the image of the address input in this cell and attribute associated to this address will be displayed on switch number one. This means an attribute block needs to be created for this address. Please note, if 0000 is input, it means the image on switch number one will not change when the switch is pressed. If no image change is desired for switch number one, type in 0000. If an image change for each switch press is desired for switch number one, look up the address of the image to be displayed from Universal Communicator 2015 and type it in. Remember to make another attribute block for the input address. 3. Address for sw2: If the switch that has this attribute block as the active attribute is pressed, and the input address in this cell is not equal 0000, then the image of the address input in this cell and attribute associated to this address will be displayed on switch number two. This means an attribute block needs to be created for this address. Please note, if 0000 is input, it means the image on switch number two will not change when the switch is pressed. If no image change is desired for switch number two, type in 0000. If an image change for each switch press is desired for switch number two, look up the address of the image to be displayed from Universal Communicator 2015 and type it in. Remember to make another attribute block for the input address. 4. End address for loop: The address input here is not used unless the timer is running. If the timer is running, each image will be displayed sequentially for the amount of time specified by Timer #1 and Timer #2 beginning with original address (address input into cell 1) and ending with the address input into this cell. What happens after the image of the end address is displayed depends on the attribute block of the end address. The attribute for the end address will be explained later in the section. Simply create an attribute block for the end address. If not running a slide show or video, type 0000 in this cell. If running a video or slide show on the switches, look up the address of the last image/video/slide from Universal Communicator 2015 and type it here. Remember to make another attribute block for the input address and enter the values according to the end address attribute block to be explained later in this section. 5.

Upon power-up, switch number one displays the image at the address 0001. Switch number two displays the image at the address 0003. 2. With no switch presses, the image on switch number one does not change. However, the image on switch number two changes every 4.08 seconds to the next consecutive address until it reaches address 0010. Then, it starts again with address 0003 and keeps repeating. 3. When switch number two is pressed, the timer for the switch number two pauses as long as the switch is kept pressed. This causes the image being displayed on switch number two to be displayed the amount of the time that switch number two was kept pressed, plus 4.08 seconds (Timer #1 x Timer #2). 4. When switch number one is pressed, it causes switch number two to display the image at the address 0002 and switch number one to display image at the address 0003 (see the red box in the table above). 5. With no switch presses, the image on switch number two does not change. However, the image on switch number one changes every 4.08 seconds to the next consecutive address until it reaches address 0010. Then, it starts again with address 0003 and keeps repeating. 6. If switch number one is pressed, the timer for the switch number one pauses as long as the switch is kept pressed. This causes the image being displayed on switch number one to be displayed the amount of the time that switch number one was kept pressed, plus 4.08 seconds (Timer #1 x Timer #2). 7. When switch number two is pressed, it causes switch number one to display the image at the address 0001 and switch number two to display the image at the address 0003.

Operational Details Power-up Sequence (Steps 1, 2, 3, 4 and 5) Upon power-up or reset the controller performs the following steps: Step 1: Initialize the OLEDs. Step 2: Display dim and bright on the two switches and allow for adjustments of the brightness. There are 16 brightness levels (0 to F). When the internal timer is expired, the controller proceeds to Step 3. Every time a switch is pressed, the timer is reset. If a switch is depressed and held, the timer does not run. Switch activity is not reported to host while depressed. Step 3: Transmit 11H to host via USB. Check the microSD for setup value. If the setup values are programmed, get the start address for switch number one, the start address for switch number two and the flag byte. If the setup values are not programmed use the default values: start address for switch #1 = 0001H, start address for switch #2 = 0010H and flag byte = 00H. Step 4: A. If the attributes for start address of switch number one are programmed, put the attribute as active for switch number one. B. If the attributes for start address of switch number one are not programmed, use the default values as active: Address for switch #1 = 0000, address for switch #2 = 0000, end address = 0010, Timer #1 = 00 and Timer #2 = 00. C. If the attributes for start address of switch number two are programmed, put the attribute as active for switch number two. D. If the attributes for start address of switch number two are not programmed, use the default values as active: Address for switch #1 = 0000, address for switch #2 = 0000, end address = 0010, Timer #1 = 00 and Timer #2 = 00.

Communication Protocol Communication Initiated by the host The controller communicates with the host via USB serial communication (57.6K, 1 start bit, 8 bit, 1 stop bit). The controller receives the data via an interrupt routine that places the data on the circular receive buffer. When the controller detects data in the circular receive buffer, the controller reads one byte and executes the following: A. If the byte is a command, the controller transmits a 61H and executes the subroutine for the command. Upon completion of the command the controller transmits 79H. B. If the byte is not a command, it is ignored. When the controller executes a subroutine, and expects additional information: A. A timer is set. If the expected data byte is not received in 64 ms, the controller transmits 6CH 6EH and terminates the routine. B. If the byte value is not acceptable (invalid range, option, etc.), the controller transmits 6EH and terminates the routine. Commands are one byte in the range of 20H to 2FH and 01H and are transmitted in hex format. The proper format for all command options and data is specified for each command. Communication Initiated by the IS-DEV KIT-7/7D The development kit transmits codes to the host via USB based on the activities stated below. Many of these reports can be enabled or disabled by the flag setup. A. B. C. D. E. F. G. Left switch press is reported as 81H Left switch release is reported as B1H Right switch press is reported as 82H Right switch release is reported as B2H Left timer expiration is reported as 83H Right timer expiration is reported as 84H Upon changing the image on the left switch, the image address is reported as FDH followed by the address in hex. A total of 3 bytes is transmitted for each image change. H. Upon changing the image on the right switch, the image address is reported as FEH followed by the address in hex. A total of 3 bytes is transmitted for each image change. I. If there is a communication problem between the microcontroller and the microSD Flash, the controller will transmit 6FH to the host for each communication issue.

Key Terms & Definitions OLED Module NKK Switches’ OLED SmartSwitches and SmartDisplays. Host Any computer, terminal, or other device that can communicate over the USB line. Controller A PCB assembly that controls one or more logic boards and the switches associated with them. It communicates with a host over the USB line. Logic Board A PCB assembly with “glue logic” for mounting switches. It is controlled by a controller. Byte An eight-bit hex value ranging from 00H to FFH (Decimal 0 to 255). The bit format of a byte is: (B7 B6 B5 B4 B3 B2 B1 B0) where B7 is most significant and bit B0 is least significant bit. Nibble/Hex Digit A four-bit value ranging from 0H to FH. A byte consists of two nibbles. ASCII A byte value representing a symbol. Communication Format There are two formats to transmit a byte: 1. Hex format - A hex byte is transmitted without any change to it. [xxH] will be used to denote this. All commands and some data are sent by using this format. 2. ASCII HEX format - Each nibble of the byte is converted to ASCII code and sent as a byte. [xxAH] will be used to denote this. For example, the hex byte 5AH is transmitted in two bytes, 35H and 41H. The ASCII value for 5 is 35H and the ASCII value for A is 41H. All addresses and most data are sent using this format. Address A two-byte value ranging from 0001H to FFFFH representing the 65,536 memory locations for pictures and attributes on microSD Flash.

It is called base-10. Every digit can be between 0 and 9. The value of each digit is equal to the digit with ((Digit order) -1) zero in front. Value in base-10 Digit x Multiplication for converting to decimal Digit order Table 1, Base-10 10000 1000 100 10 1 100 10(N-1) … … 104 103 102 101 Nth digit …. …. Fifth digit Fourth digit Third digit Second First digit digit Example: The value of each digit of the Base-10 number 7605 is as follow: Fourth digit: Third digit: Second digit: First digit: 7 with (4-1) zero = 6 with (3-1) zero = 0 with (2-1) zero = 5 with (1-1) zero = 7000 600 0 5 Numbering system A numbering system can be based on any number (Base-N). However, it must follow the rules: 1. Each digit must be between 0 and “Base minus one”. For example: ---Each digit for Base-2 numbering system can be 0 or 1 ---Each digit for Base-5 numbering system can be 0 to 4 ---Each digit for Base-8 numbering system can be 0 to 7 2. The value of each digit is equal to the digit with ((Digit order) -1) zeros in front. All the operations that we use on base 10 numbering system (such as addition, subtraction, multiplication, division) work the same for all the numbering systems. The difference is the carry over will be based on the base-number of the numbering system instead of 10. Why do we need other base numbering systems? Computers logic is based on two states: Yes or No False or True High Voltage or Low Voltage IS-Dev Kit-7 User Manual E.docx Toll Free 1.877.2BUYNKK (877.228.9655) • Phone 480.991.0942 • Fax 480.998.1435 www.nkkswitches.com • Email engineering@nkkswitches.com Page 47 of 51 1120 IS-DEV KIT-7 User Manual 7850 East Gelding Drive • Scottsdale, AZ 85260-3420 Base-2 numbering system (binary) The numbering system to accommodate the computer logic is called binary or base 2. Each digit of binary can be 0 or 1. Value in base-2 Digit x Multiplication for converting to decimal Digit order Table 2, Base-2 10000 1000 100 10 1 20 =1 2(N-1) … … 24 =16 23 =8 22 =4 21 =2 Nth digit …. …. Fifth digit Fourth digit Third digit Second First digit digit Example: The value of each digit of the Base-2 number 1010 is as follows: Fourth digit: Third digit: Second digit: First digit: 1 with (4-1) zero = 0 with (3-1) zero = 1 with (2-1) zero = 0 with (1-1) zero = 1000 0 10 0 To convert a base-2 number to decimal, multiply each digit by multiplier and add them together: Example: converting base-2 number 1010 to decimal is as follows: (1 x 8) + (0 x 4) + (1 x 2) + (0 x 1) = 10 To convert a decimal number to base-2 number ---divide the decimal number by 2, the remainder is the first digit of the base-2 number --- continue dividing quotient by 2 and put the remainder as the next digit until the quotient is equal to 0. Example: Convert the decimal number 21 to base-2 21 divide by 2 = 10 with 1 remainder 10 divide by 2 = 5 with 0 remainder 5 divide by 2 = 2 with 1 remainder 2 divide by 2 = 1 with 0 remainder 1 divide by 2 = 0 with 1 remainder First digit = 1 Second digit = 0 Third digit = 1 Fourth digit = 0 Fifth digit = 1 21 decimal = 101001 base-2 or binary The base-2 number 101001 reads as one zero one zero zero one.

To make it easier to present computer data, a hexadecimal or base-16 numbering system is used. Four digits of base-2 numbering system converts to one digit of base-16 numbering system. Since we did not have digits for 10, 11, 12, 13, 14 and 15, they were assigned letters A, B, C, D, E and F respectively.
