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...

GCC optimization -01 creates clocks problems (using Free

Hello world!I'm working on a real-time synthesizer project since a few years :using STM32F427VGST drivers V1.0.0 not HAL (I think HAL wasn't existing in the past) Everything is working well with optimization -O0.When I enable optimization (eg -O1) co...

Can you send a message over UART in a callback function?

I am implementing the conversion complete callback function for the ADC and am trying to send a message over UART when this completes. However, it does not seem to want to work. I have independently verified that both the callback function is being c...
