Robert Fischer / Mbed 2 deprecated TFTLCD_Fork_Test

Test of new controller lib SSD1963 and HX8352-A

Dependencies:   TFTLCD mbed

Test for the new libs. I implemented a driver lib for SSD1963 (TFT 272x480) and HX8352-A (TFT 240x400). Both displays have a 40 pin connector with same pin.

Image of the 240x400 board with HX8352-A /media/uploads/RobertFischer/hc8352_240x400.jpg

I used a ST Nucleo F401RE for testing. The 16bit databus is connected to port C (DB0->PC_0, DB1->PC_1...) Control pins: CS -> PB_1 Reset -> PB_0 RS -> PB_7 WR -> PB_6 RD -> PB_2 (not needed, there is no procedure for reading data from display controller) BL -> PB_13 (PWM back lit control. Not tested yet.)

Both displays need a 16 bit bus for command and data and 4 or 5 pins for control.

I discovered some strange problems with my Nucleo board. It seems there is a power issue using this quit big displays. I had some wired output on display. After stetting jumper to E5V and powering the board from a 5V supply, it looks very good.

TODO:

  • Testing the touch sensor
  • Wiring and testing SDcard connector
  • Testing with a Freescale FRDM board
