Resolved! DMA and GPIO on STM32C031G6

I would like to sample the entire GPIOA Port using the DMA and TIM16. TIM16 triggers the DMA which in turn is supposed to copy the content of the IDR register of GPIO onto an array. This works fine if I use the CNT register of TIM16 as CPAR. When I s...

STM32H7R3I8K6 vs STM32H750IBK6 current draw?

I'm trying to get a ballpark estimate of what sort of current draw consumption I can expect if we migrate to the H7R3, which uses a SMPS for the core, as opposed to the built-in LDO for the core on the H750.Is there a place I can compare the current ...
