USE_HAL_***_REGISTER_CALLBACKS and HAL_SPI_xxxCpltCallback not called
After each project update, CubeMX 5x/6x changes the values of all USE_HAL_***_REGISTER_CALLBACKS definitions in stm32h7xx_hal_conf.h header file. This makes it extremely difficult to use the callback functions.PS:Hi, today I lost the whole day to fin...

Enabling freeRTOS should not require setting system time base when using LL
By default, when using HAL, it is required to set another time base source instead of SysTick as it is used for freeRTOS, but when using LL for all the peripherals, it shouldn't be necessary as LL does not use SysTick interrupt as HAL does.I think th...
USB host doesn't support hubs but some dual function keyboards work - how?
We are still waiting for USB Host Hub support (will it ever arrive?) but in the mean time I'm trying to understand how some keyboards with built in touchpads work but others don't. Obviously, if they have a built-in hub and the keboard always connect...
