/* ITEAD 2.4" TFT with Touch
|
|
|
|
|
*
|
|
|
|
|
* The Arduino 2.4" TFT Touch Shield is designed for all the Arduino
|
|
|
|
|
* compatible boards. It works in 3.3V voltage level. It can be directly
|
|
|
|
|
* plugged on the Arduino and other compatible boards. It will offer
|
|
|
|
|
* display, touch and storage functions for the Arduino board
|
|
|
|
|
*
|
|
|
|
|
* Features:
|
|
|
|
|
*
|
|
|
|
|
* 1. Compatible with 3.3/5V operation voltage level
|
|
|
|
|
* 2. Compatible with UTFT library
|
|
|
|
|
* 3. With SD Card Socket
|
|
|
|
|
*
|
|
|
|
|
* The Arduino 2.4" TFT Touch shield uses the S6D1121 controller , it
|
|
|
|
|
* supports 8-bit data interface. The touch IC is TSC2046.

|
|
|
|
|
* and the SD card.
|
|
|
|
|
* 2. UART0 cannot be used. USARTs on the COMM connector should be available.

|
|
|
* 3. Parallel data is not contiguous in the PIO register
|
2013-07-02 19:36:48 +02:00
