suu pen / Mbed 2 deprecated ArduinoTFTLCDScreenSample_SPI18TFT

This sample program is for Arduino TFT Screen module.

Dependencies:   ST7735_TFT mbed

Fork of SPI18TFT by Jonne Valola

mbedとArduino TFT LCD Screenとの接続について

Arduino TFT LCD Screenswitch science webをmbed(LPC1768)で制御するsample programです。ベースにしたprogramはSPI18TFTです。

LCD moduleとmbedの接続はベースソフトと同じです。以下に接続図を示します。
