Program microcontroller in Python using ctypes to utilize HAL libraries

I am familiar with the STM32CubeIDE; I've done several of the examples and understand how it works on a basic level. What I need to do is create a user-interface (hence needing Python) that will allow a user to interact with the microcontroller. Ctyp...

Correct way to end DMA

Our STM32F7 no-OS system calls HAL_MMC_ReadBlocks_DMA() to read multiple blocks of data from eMMC storage.The STM HAL sets the MMC state machine SDMMC_DTIMER register at the start of the DMA.The DMA completes and our code receives the interrupt and h...
