PIC-MAXI-WEB

PIC-MAXI-WEB development board Users Manual Rev.B, April 2009 Copyright(c) 2009, OLIMEX Ltd, All rights reserved Page 1 INTRODUCTION: This board allows you to easily develop Ethernet connectivity applications. It has everything you normally would need for such applications: power relays which you can command through web interface, LCD display which will display messages you fill in web forms, analogue inputs for connection to sensors, digital optoisolated inputs, trimmer potentiometer, temperature sensor, Ethernet connector. With this board you can easily automate your home and then control and monitor it from any point in the world via Internet. An extension connector is available so you can connect custom made hardware to the board. The PIC18F97J60 has 128KB Flash program memory and there is external 1Mbit (128KB) flash memory for data storage. The on board DC/DC converter makes this board very tolerant to the external power supply which could be in 9-25V DC or 7-18V AC range. The bridge rectifier on the input allows AC and DC adapters to be used and makes power supply polarity problems go away. BOARD FEATURES: PIC18F97J60 microcontroller with embedded Ethernet MAC and PHY and 128KB Flash programming space 1Mbit on board serial flash for web pages storage ICSP/ICD connector for programming and debugging with PICICD2 and PIC-ICD2-POCKET. Temperature sensor Trimmer potentiometer connected to analogue input Two relays 10A/250VAC Four optoisolated digital inputs Twelve analogue inputs on terminal block Two buttons LCD16x2 with backlight RS232 interface Ethernet interface Complete web server and TCP-IP stack support as per Microchip's open source TCP-IP stack Terminal block for power supply works with 9-25 VDC power supply Extension header to connect to other boards Dimensions 120x108 mm (4.72x4.25") ELECTROSTATIC WARNING: The PIC-MAXI-WEB board is shipped in protective anti-static packaging. The board must not be subject to high electrostatic potentials. General practice for working with static sensitive devices should be applied when working with this board. BOARD USE REQUIREMENTS: Cables: Depends on the used programming/debugging tool. It could be 1.8 meter USB A-B cable to connect PIC-ICD2-POCKET or PIC-ICD2 to USB host on PC or RS232 cable for PIC-ICD2-TINY and PIC-ICD2. You will Page 2 need a serial cable if not for programming, than for configuring the board. You will also need a LAN cable. Hardware: Programmer/Debugger –Olimex programmers are applicable, for example PIC-ICD2, PIC-ICD2-POCKET, PIC-ICD2-TINY or other compatible programming/debugging tool. !!!Warning!!! When you want to program this microcontroller with PICICD2, PIC-ICD2-POCKET or PIC-ICD2-TINY, before connecting the programmer to your target board, you should first connect the programmer to your computer and open MPLAB. There, first from menu Configure – Select Device – choose the microcontroller you are about to program, then from menu Programmer – Select Programmer – choose MPLAB ICD 2, wait while MPLAB is downloading operation system, and after ICD2 is connected – check in menu Programmer – Settings – Power – there is option – Power target circuit from MPLAB ICD 2 – this option should be forbidden, you could not select it. Now it is safe to connect the programmer to your target board. Software: PIC-WEB is tested with MPLAB IDE v.7.62 + MPLAB C18 C compiler. It is possible that the stack might not function properly if used with later versions of MPLAB IDE. You will also need a terminal program configured at 19 200 bps, 8N1 and no flow control.

The board power consumption is about 200 mA with all peripherals and MCU running at full speed, relays and LEDs on and working Ethernet connection. RESET CIRCUIT: PIC-MAXI-WEB reset circuit is made with RC group R20 – 10k and C31 – 100nF. Serial resistor R21 – 330Ω is used to prevent fast C31 charge and discharge when PIC18F97J60 is being programmed. Manual reset is possible by the RESET button. CLOCK CIRCUIT: Quartz crystal 25MHz is connected to PIC18F97J60 pins OSC1 (CLK1) and OSC2 (CLKO). Internal PLL circuit can multiply this frequency up to 41MHz. 32.768 KHz quartz crystal is connected to PIC18F97J60 pins T1SO and T1OSI for its internal Timer1. Page 9 JUMPER DESCRIPTION: 5V_E enables 5V supply for LCD and relays. Default state closed (shorted). 3.3V_E enables 3.3V supply for PIC18F97J60 and all other devices. Default state closed (shorted). 3.3V is also available to EXT-1, so if you want to connect external backup battery to the PIC18F97J60 this jumper should be opened and the external battery to be connected to EXT-1 pin. #SS1/#SS2 chip select for U5 (AT45DB011) serial flash. Default position is selected to be #SS2 in compatibles with Microchip software but user can change it in its own application. Default state closed (shorted) INPUT/OUTPUT: Two User buttons with names BUT1 and BUT2 – connected to PIC18F97J60 pin 8 RB3/INT3/ECCP2(1)/P2A(1) and pin 6 RB1/INT1; One analog trimmer AN_TR – connected to PIC18F97J60 pin 33 RA2/AN2/VREF-; Thermistor TH1– connected to PIC18F97J60 pin 32 RA2/AN2/VREF+; Three LEDs – LD0 (yellow) – connected to PIC18F97J60 pin 49 RJ0/ALE , LD1 (red) – connected to PIC18F97J60 pin 50 RJ1/#OE, LD2 (red) – connected to PIC18F97J60 pin 66 RJ2/#WRL; Four opto isolated digital inputs IN1-IN4; Four red LEDs – LED1, LED2, LED3, LED4 for every digital input; Two green LEDs – LED5, LED6 – for the relays; Power supply red LED with name PWR_LED – indicates that 3.3V power supply is available Twelve analog inputs X1-X6; LCD Display - SC1602A - 16 characters x 2 lines.
