Ok, Tectu ask me, but i can't send PM, so I have to answer this way - here is my current status: My plan is to create project using Em::Blocks IDE for STM32 Camera rev. 3.1 board with uGFX. Currently i've created project, added ugfx and created gos/baremetal.c and gos/baremetal.h - actually based on Chibios template. I've created gfxconf.h and set new definition GFX_USE_OS_BAREMETAL. Now i'm resolving compilation errors because of the new system definition (i'm totally new with mutexes, semaphores, etc... so please be patient) Pablo2048
