ST7783 driver

Postby Miogui » Thu Jun 13, 2013 6:33 pm

Hi all

I've just started a new project on a STM32F4 board + TFT ST7783


Image

I`m looking for a driver for my TFT based on the ST7783.

Is there someone who have already worked on this feature ?
Or maybe this driver got the same caracteristic than an other ?

Many thanks

Plop..


I know it's fast,

but I found an C driver on the web and started to write a new GFX driver for this screen..

The Screen is now powered, and I've got the benchmark working...
But I've got some issue with the Ram alignement (I think).

The picture are on the top half of the screen and each line are shift... ???

Maybe this come from the RS pin, connected to the PE3 pin (A19). I'm not sure about this :
#define GDISP_REG ((volatile uint16_t *) 0x60000000)[0] /* RS = 0 */
#define GDISP_RAM ((volatile uint16_t *) 0x60100000)[0] /* RS = 1 */

Wow, that's really good performance:)

Can you share your code with us? Maybe it could be joined into drivers codebase of ChibiOS/GFX:)

A new driver? Cool!
I'm sorry that I couldn't answer your questions before but there was some after-final exams festival going on >.< But as I can see, you made quite nice without any help. Good work!
