Series: Getting Started with GT-CP

Getting Started with GT-CP | Case Study : Image Gallery And Slider Program


Case Study : Image Gallery And Slider Program

As part of the Getting Started with GT-CP series, we will actually run the program using an Arduino connected to GT-CP. For details, please refer to Direct control in Step 8. This time, we will display the numeric keypad and show how the operation is actually performed by touching it.

Depending on your PC environment, you may not be able to connect USB to Arduino and GT-CP at the same time for writing.

Sample programs for Image Gallery And Slider

 

This is an actual sample program that runs on an Arduino connected to the GT-CP via UART.

This program is used to select photos and adjust brightness with a slider.

Preparation of Host Board

Please obtain an Arduino Pro Mini or equivalent in advance. It must have a CPU capable of outputting a stable 38,400 bps via UART and a signal voltage specification of 0 to 3.3V.

Compile the Arduino Sketch file and upload it to Arduino. See the sample program at the bottom of the page.

Preparation of GT-CP Module

Check the specification sheet and set the interface specification to UART (Baud Rate 38,400 bps). For GTWV070C300PA, set JP5 and JP6 to Short respectively, and the remaining JP1-JP4 and JP7-JP10 to OPEN.

Connect to the PC with the USB cable and turn on the power to the Module.

Connection of GT-CP Module and Host (Arduino)

Refer to the wiring diagram below to connect the GT-CP Module to the Host (Arduino).

Turn on the power and the Sample Program will be executed.
