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
