HAL equivalent for ADC_DMARequestAfterLastTransferCmd() in std_periph
I am working with the STM32 Nucleo-F401RE board trying to perform ADC reads from a CCD line sensor, which have to be performed at a rate close to the possible maximum for the MCU. I have a example firmware doing exactly what I want on the discovery board I use 1.
Unfortunately, this firmware seems to be written using the std periph library, while any I would prefer using HAL. My issue is that I cannot find a proper replacement for ADC_DMARequestAfterLastTransferCmd(), which seems to play an integral role in setting up the DMA. I can’t find proper documentation on what exactly it does, so, the following problem keeps bugging me:
Questions:
What precisely is this function doing? The name (and some rudimentary documentation) indicate it would be a setting to schedule DMA requests. But I could not translate this to low-level actions.
What would be the replacement function in HAL? If not, how could I create a manual implementation?
