2.1
2.1.1
Overview and Operation of the DCP Evaluation Platform
Hardware Overview
ISLUSB2DCPMBEV1Z Interface Board (Motherboard)
The motherboard provides the interface between a PC and DCP evaluation board (daughter card), as shown in
Figure 1. A USB cable, with type A and B connectors on each end, is required to plug the board into a PC
(schematic of ISLUSB2DCPMBEV1Z board in Appendix A). The ISLUSB2DCPMBEV1Z board is powered from
the USB port. It contains a microcontroller (U1) with USB interface (J1) for communicating with the PC, and I/O pin
connector (J2) to supply power and communicate with the DCP daughter card.
The mother board also provides power to the daughter card either from the USB port or from an external power
supply through the adjustable voltage regulator (U4). An external power supply can be connected to JP2 (+6V)
and JP3 (GND) hookup pins. A JP5 jumper allows the selection between USB or external power. An on-board
inverter (U6) generates negative voltage from U4 output. Both positive (VCC) and negative (V-) outputs are
controlled through the Graphical User Interface (GUI) of the DCP evaluation software.
The U2 MUX minimizes the number of J2 pins by mapping selected interface to the daughter card connectors J2
and JP6. The J2 and JP6 mapping is fully compatible with previous generation of DCP evaluation boards, such as
the XLABVIEW01 board. The voltage at VIN0, VIN1, VIN2, and VIN3 pins of JP8 can be measured through the
onboard ADC. Usually these inputs are wiper outputs from the daughter card. Note: The ADC can measure only
positive signals from 0V to 5.5V; negative inputs are blocked out by Schottky diodes D3~D6.
2.1.2
DCP Evaluation Board (Daughter Card)
Each DCP daughter card is different, but typically contains one DCP device, one or two connectors to attach to the
mother board, and a DCP terminal header allowing different terminal configurations, such as connection to VCC,
GND, V-, or to each other.
The ISL22317 daughter card (shown in Figure 2) has a JP1 male connector to match with the JP2 female
connector of the mother board to provide VCC, V-, GND, and I2C interface signals to the DCP. The JP2 male
connector provides wiper outputs back to the mother board through the matching JP8 to be measured and

displayed on the GUI, or measured from the terminal header JP4. The DCP terminals RH, RW, and RL can be left
open, or connected to VCC, V-, each other or external circuitry by using jumpers. The VCC power is supplied
through the JP3 jumper from the motherboard. The JP3 header also allows measuring power consumption of the
DCP by connecting an ammeter between the JP3.1 and JP3.2 pins instead of a jumper, or use an external power
supply connected to JP3.2.

The product demonstration GUI automatically appears when the interface is selected as shown in Figure 4. It
starts up with the Manual Setup window, where you can choose items such as a number of taps, number of DCPs
in package (such as single, dual, or quad), slave address, address pin settings A0~A4, enable or disable VCC,
and V- outputs.

Figure 4. I2C Interface Product Evaluation Window, Manual Setup
There are convenient initial setups available for Renesas supported I2C DCPs from the Device Select pull-down
menu, located on the menu bar, -> Parameter file as shown in Figure 5.
Figure 5. I2C Device Select Pull-Down
All executable functions are separated by individual frames that provide more visibility and convenient. All white
text boxes have either a pull-down menu, selectable, or type-in capability. Type-in capability means that you can
type in a new value, hit the Enter button on the keyboard, or Write/Read software button, and this data is
executed by the software. Gray boxes are read only.
The interface clock frequency for the I2C interface is selectable from a pull-down menu as well.
3.2
VCC Control
To start communication with the DCP, the on-board voltage regulator has to be turned on. The regulator control
(such as VCC Control) is located in the upper left corner of the GUI. There are several VCC options available in
the pull-down menu from fixed to user-adjustable. By default, VCC is set to 5V. The negative V- voltage tracks the
VCC or can be turned off.

Digitally Controlled Potentiometer (DCP) Evaluation Kit Manual
The VCC level is automatically sampled by an on-board Analog-to-Digital Converter (ADC) every time the VCC is
turned on or off, or can be manually sampled by pushing the Sample VCC button.
The ADC requires calibration to receive the correct VCC readings. The calibration procedure is shown in the
following steps:
1. Set the VCC level to 5.0V. Use an external voltmeter to measure the actual VCC output and record its reading
as Measure1. Write down the ADC reading as Read1.
2. Set the VCC level to 3.0V. Write down the voltmeter reading as Measure2 and the ADC reading as Read2.
3. Calculate the ADC Gain using Equation 1.
(EQ. 1)
Measure1 – Measure2
Gain = 2 ----------------------------------------------------------------Read1 – Read2
4. Enter the new Gain value and repeat the measurement starting at Step 1.
5. The ADC Offset = Measure1 - Read1. The calibrated Gain and Offset values can be written down directly on
the ISLUSB2DCPMBEV1Z motherboard and should be used for correct readings.
3.3
Set Wiper Position in I2C interfaces
The wiper position can be set by moving the slider or by typing in a hex or decimal value in the corresponding text
box, see Figure 4. Software automatically reads back the wiper register if the Auto Read box is checked out.
Each DCP channel has its own wiper control and read capability. Set the wiper position in the Up/Down and
Push-Button Interfaces
3.4
Set Wiper Position in Up/Down and Push-Button Interfaces
To move the wiper in an up or down direction, enter the number of counts in corresponding text box as shown in
Figure 6 and push the Up or Down button.
Enter the number of taps
wiper is going to Up or Down

Script Execution
The DCP evaluation software allows multiple commands to be executed, which were written in sequence in a
script file. A script file is a text file written in Notepad or other simple text editing programs. There are some
examples of script files provided for your convenience, that can be opened by following Script Execution > File >
Open Script File from the menu bar. Script files can be executed only in I2C and SPI interface product windows.
Script execution is not supported for Up/Down and Push-button DCPs.
4.1
I2C Script File
The structure of the command line for the I2C interface is a Slave Address followed by a Register Address, Write
Data, Read Data, and Comments. The data in the command line is separated by a comma without spacing. All
spaces are ignored.
The Slave Address should be written once at the beginning of the command sequence, starting with an acute
symbol and letter A. For example, ‘AA0 for Address A0 or ‘A50 for Address 50. This slave address is used for all
lines below in the sequence until the next address line, if a script file is written to communicate with several DCPs
on the bus. Comments must start with the number sign (#) followed by any ASCII symbols.
The Write Data or Read Data can be omitted for Read only or Write only operation. For example:
▪ 00,55, #write 55 to address 0 without reading back
▪ 00,55,55 #write 55 to address 0, then read back from address 0. The read data is compared with 55
▪ 00, ,55 #read from address 0 and compare result with 55
The wait command starts with the acute symbol followed by a letter w and a number that represents waiting time
before execution of the next command in milliseconds. For example, ‘w1000 #delay for 1000ms. The script
execution window is shown in Figure 7.
Figure 7. ISL22316 Script Execution Example
AN1555 Rev.2.00
Jan 10, 2022
Page 7
Digitally Controlled Potentiometer (DCP) Evaluation Kit Manual
Successfully executed commands are highlighted by a green color, while non successful command or unexpected
returned values are highlighted by a red color. A script file can be executed at once, or put in a loop by pressing
the Run All Steps or Loop Count buttons in the upper right corner of the Script Execution Window. The actual
read data can be stored in an updated script file by specifying a path and pressing the Write to Disk button.
