Does the uGfx demo (when using ChibiOS) relies on the discoveryF746 board.h file provided by ChibiOS ? If so, i have seen that there is some differences for this board between the definitions provided by ST CubeMX and the ones in ChibiOS board.h Saying that, i have tried to fix chibios board.h, with no success (now the screen goes black after init, but still nothing displayed on it) Alexandre

For whatever reason, PAL_STM32_PUDR_FLOATING is now in 3.x PAL_STM32_PUPDR_FLOATING. With this small change, demo compile and works. Alexandre

Ok, my stupid fault : i didn't enable I2C3 in mcuconf.h and I2C in halconf.h remains an error : mouse_lld_STMPE811_board.h use PAL_STM32_PUDR_FLOATING macro which was valid in chibios 2.6 but which is not defined anymore in chibios 3.X (and there is no replacement from chibios header, so i guess it as to be declared in GFX source) Alexandre

Hello. I had managed to compile and use STM32F429i-Discovery with GFXDEMO = applications/combo last year with chibios 2.6 (as a start for giving a for student project). This year, we have made the transition to chibios 3.x, so i did compile with success STM32F429i-Discovery with GFXDEMO = modules/gdisp/basics, but when i try with GFXDEMO = applications/combo, compilation fail. I use chibios svn version stable 16.1.5, and gfx 2.6 up2date from master git. The error come when compiling drivers/ginput/touch/STMPE811/gmouse_lld_STMPE811.c : So it seems that when it compiles gmouse_lld_STMPE811.c, for an unknown reason, it has forgotten all the symbols from chibios header. Any clue about that ? Thanks Alexandre

Thanks for this information. Well, i planned to use a disco_F746 for a project for students, which is beginning .. now, but I think that the goal that I ask (an ADSB transponder simulator to simulate and detect garbling) can be achieved with a disco_F429, so, since disco_F429 ufgx/chibios port works, i will, in the first time ask my students to use a disco F429. It will even be easier for the student because their real time / rtos course is based upon chibios 2.6. In my spare time, i will try to see if i can detect where disco_F746 port fail .. Alexandre

Hello, this is my first post, i 'll begin with a big thanks for this open source graphic library in the spirit of our beloved ChibiOS. As a total newbie, i try the discoF746 ChibiOS demo. After adding some include path in makefile, it compiles. When flashed to the devboard, the screen just get white and nothing more. I have added a blinker task to main.c , so i can see that the processor is not stuck since the led blinks. I use Chibios3 from master branch. I need and advice to know where to search to make this demo works, and then begin my own project. EDIT1 : the raw32 version demo is working. Does the ChibiOS version only works with known version of chibios ? if so, what is/are the version known to work ? EDIT1.1 : does not compile with 3.0.4, compile but just show whitescreen with 16.1.0 and 16.1.1 Thanks, Alexandre
