  5. STM32F429I-discovery working example?

    in Support

    Posted

    My primary problem is that I don't understand the links between the uGFX and ChibiOS - should ugfx use any chibios drivers for this board or does ugfx have it's own drivers and ChibiOS should only run the self-containing ugfx code - so in fact ugfx uses only chibios's make system, no header files, no object files?

    The before-mentioned ugfx demo for FreeRTOS also uses some ST library (STM32F429I-Discovery_FW_V1.0.1/Libraries/STM32F4xx_StdPeriph_Driver and STM32F429I-Discovery_FW_V1.0.1/Utilities/STM32F429I-Discovery) which brings even more confusion for me :(

    I don't grasp what I should set in the Makefile - there are at least four options:

    1. include $(CHIBIOS)/boards/ST_STM32F429I_DISCOVERY/board.mk

    2. include $(GFXLIB)/boards/base/Mikromedia-STM32-M4-ILI9341/ChibiOS_Board/board.mk

    3. include $(GFXLIB)/drivers/gdisp/ILI9341/driver.mk

    4. GFXBOARD = Mikromedia-STM32-M4-ILI9341

    ...and also ST libraries and ChibiOS's USE_FWLIB option...

    I've tried all of them and several combinations of them without luck... Hence I would really need complete working example to have something to start with...

    The code in https://github.com/mprymek/bubbles-stm32f429 compiles with http://pastebin.com/HP16WZnR

    The missing header file is found in boards/base/Mikromedia-STM32-M4-ILI9341/board_ILI9341.h but when I try to add it with

    include $(GFXLIB)/boards/base/Mikromedia-STM32-M4-ILI9341/ChibiOS_Board/board.mk

    I get http://pastebin.com/2KmXTV1e -- from this I suppose this board file is for other hardware and is not usable for .

    There was some discussion about STM32F429 board file (viewtopic.php?f=22&t=51) but I don't see any usable output of it...

    So do I understand it well that to use ugfx with STM32F429 and ChibiOS, I would have to write a new board file? (It would be probably too hard for me as I am not experienced with either ChibiOS or ugfx...)

    My other tries (maybe totally worng way) with compiler outputs can be seen at https://github.com/mprymek/bubbles-stm3 ... ommits/tmp

    Hello,

    I'm new to the world of 32bit mcus and trying to get familiar with RTOSes. I like ChibiOS very much but can't get STM32F429I-discovery work with ugfx and ChibiOS. Please do any of you have a complete working example of anything little bit more complex like e.g. ugfx notepad, with proper ChibiOS makefiles etc.?

    I have managed to compile https://github.com/winfred-lu/stm32f429-freertos800 but I would prefer to experiment with ChibiOS rather than FreeRTOS and unfortunatelly did not find any complete, working ChibiOS example code.

    I was also trying to adapt code of "bubbles" example from http://ugfx.org/demos but unfortunatelly without any luck. I tried to look at the code, changed some constants etc. but only got compile errors which are cryptic to me...

    I have asked this question on ChibiOS forum already ( http://forum.chibios.org/phpbb/viewtopi ... 79&p=18205 ) and was told to ask here :)

    I would be very grateful for any complete source code for STM32F429I-discovery I could start with.

    Thank you very much for any suggestions, hints, etc.

    P.S. I prefer to work with just vim & make. Examples for commercial IDEs which can't be compliled with simple make are troublesome for me...
