Ugfx & ChibiOS - STM32F746G-Discovery

[tupak]

Hi!

I have a STM32F746G-Discovery board and I need to run Ugfx & ChibiOS together.

I tested the ugfx demo and works fine!

But How I can integrate with Chibios? What version of Chibios works well with ugfx?

Thanks!

Regards.

Both ChibiOS 2.6 and ChibiOS 3.x are known to work very well with uGFX. ChibiOS is what most uGFX users use as uGFX originated as a ChibiOS/RT extension/add-on.

However, there's a known issue with the STM32F7 board files of uGFX and ChibiOS. It appears that the STM32F7 headers used by our board file and the one used by ChibiOS/RT are incompatible. Sadly we haven't had time to track down the issue ourselves so far. Last time we checked it seemed that ChibiOS/RT uses older headers than uGFX. But it's possible that it's the other way around or maybe the issue resolved itself by now - we haven't checked up on the state of the STM32F7 support on the ChibiOS/RT site of things for quite some time now.

Note: The issues are really just related to the peripherals (LTDC, FMC and so on). The CPU part and all that magic works just fine.

We would really appreciate it if you would have a look at the problem and potentially fix it. You can find further information here: viewtopic.php?f=23&t=334
