3. Usage Instructions

3.1 Connections

① Connect both CN1 and CN2 headers on the application board to the corresponding CN1 and CN2

connectors on the CPU board. Make sure both headers are inserted to match the direction and number
of pin numbers and the pins are fully inserted into the sockets.

② Insert the mini B plug end of the USB cable included in the kit into the CN6 pin on the CPU board, and

insert the opposite side of the cable into the USB port on the PC.

③ PC operation: The USB serial port driver is automatically installed the first time it is connected to the

PC (when using Windows7). Note: Do not remove the USB cable during driver installation.

After the driver auto-install is complete, download the driver that corresponds to your operating system
from the FTDI website below, and install it manually.

RX130 Group RX Capacitive Touch Evaluation System Quick Start Guide

④ CPU board operation: When the USB cable is connected, the CPU board automatically recognizes the

connected application board and starts the corresponding demo program. The demo program can be
identified by the LEDs on the CPU board.

 LED1: Mutual-Capacitance Button / Proximity Sensor Board
 LED2: Self-Capacitance Buttons / Wheels / Slider Board

If the LEDs don’t illuminate in response to touch panel operations, make sure the switch and jumpers
on the CPU board are set as shown in Figure 3-2. After confirming the correct settings, press the reset
button (SW2) to restart operations and check the LEDs again.

3.2 Demo Program Operations

① Mutual-Capacitance Button / Proximity Sensor Board

Touch button input is enabled when the proximity sensor starts to respond.

 After the USB cable is connected, the application board will illuminate the LEDs in sequence.

Please do not touch the application board during this initial adjustment of the touch sensors.

 When initial adjustments are complete, all LEDs will turn off.
 Moving a hand close to the surface of the application board will illuminate all LEDs, indicating touch

button input is enabled.

 Each LED will turn on or turn off, accordingly, each time touch button input occurs.
 If no touch button input occurs for a period of 5 seconds, all LEDs will turn off and touch button

input will be disabled.

② Self-Capacitance Buttons / Wheels / Slider Board

The LEDs indicate electrode touch positions.

 After the USB cable is connected, various LEDs on the application board will turn on. This is part of

the touch sensor initial adjustment period−please do not touch the board at this time.

 When initial adjustments are complete, all LEDs will turn off.
 Moving a finger around the wheel (electrodes) will illuminate the associated LEDs.
 Sliding a finger up and down the slider (electrodes) will illuminate the associated LEDs.
 Pushing a button will illuminate the LED at the top of the button.
