Florian Posted April 10, 2014 Report Share Posted April 10, 2014 Hello,I have a question in order to the evaluation Board STM32F4Disco (STM32F429).The question relates primarily to the built in STM32F429 CortexM4 controller.These CortexM4 has an LCD-TFT-Controller inside. Can I use this controller instead of an external display controller like the SSD1963?What I have to note / to do to use the internal controller of the CortexM4. Is there an example, which I can use?Thank's a lot.Florian Link to comment Share on other sites More sharing options...
Joel Bodenmann Posted April 10, 2014 Report Share Posted April 10, 2014 Hello Florian and welcome!It is possible to use the internal controller of the STM32F4x9. However, there is no official support yet so you would have to write the board files yourself. The board file is that part where the uGFX library can say "hey man, draw a green pixel at the coordinates 13/37!" - inside that file you'll have to talk to your LTDC peripheral. The LTDC is then responsible to drive the display panel.If you plan to use ChibiOS/RT, one of the guys there already wrote a HAL and got the display working. The board file is really nothing but a wrapper around that. Note that there's already a driver for the ILI9481 display from our side as well.I hope that helps.~ Tectu Link to comment Share on other sites More sharing options...
