ugfx LTDC and chibios

Hi

Is there any example use ltdc with https://github.com/ChibiOS/ChibiOS-Contrib.

I test ugfx with STM32F429i-Discovery board on chibios 3 but not work.

inmarket is currently working with the STM32F7 Discovery board using ChibiOS 3. He mentioned some issues but I am not sure whether he managed to get it working yet so we better wait until he drops by.

The stm32f4-discovery was working with chibios 3. That however was a while ago. A few things have changed since then...

1. We have changed the driver used by the f429 ftom a specialist driver to a generic ltdc driver.

2. Chibios v3 api has changed (it is not yet a stable api product unlike v2)

3. The current version of the stm32 library has changed.

4. We have changed the make system for chibios3 but the f429 example probably still uses the old settings.

Consequently it is not surprising that it does not currently work slthough i am sure the problems are small as it has worked in the past. The f7 board however has more serious issues and we have not yet got it working with chibios3 although it does work using raw32 and keil cmsis. That problem I think it is something to do with io init sequencing. That however is not the problem with the f4 board.

We would love it if someone was to take the initiative and find any problems. Unfortunately as maintainers we have a lot on our plates currently as we are working on new often requested features (plus our normal day jobs) so leaving it to us vould take a while. We will help wherever we can.
