'Best Answer' is misleading - should be 'Solution'

On the old forum, we had ‘Mark As Solution’This is good: people come to the forum looking for solutions - so it is important to mark when a solution is found. The current forum calls this ‘Best Answer’ instead.This is bad: the best answer does not n

STM32H7B0 DFSDM has eight filters but only four DMA lines?

I’m starting a project with the STM32H7B0 which will heavily utilize the DFSDM (DFSDM1, specifically). I see that there are eight filters in this instantiation, unlike other STM32s I’ve used which only had four. But when I look at the DMAMUX inputs

X-CUBE-CRYPTOLIB V5.x.x – Thread safety and reentrancy confirmation

Hello ST team,In a previous discussion, @Jocelyn RICARD confirmed that X-CUBE-CRYPTOLIB V4.x was not reentrant, partly due to its use of the CRC hardware peripheral.I understand that V5.0.0 no longer depends on the CRC peripheral, but I could not fi
