Bare-metal STM32F030C8.Using input capture to receive encodes.Encodes are delimited by idle.I need to decode only the last 10 or so transitions of each encode.I want to perform the decode during the idle.So I’m using circular DMA and I want the timer...

Line 6 is a waste of code. Isn't line 7 copying data over buffer? In embedded development especially, all code should be for a reason and no code should be without a reason.Line 7 should use vsnprintf. Else what would happen if the format or its expa...

I mean the access size of the CPU's load/store instruction, e.g. 1, 2, or 4 bytes.

As I'd said earlier, neither the CPU nor any STM32U5 bus can perform an access at an address that isn't divisible by its access size. So memory-mapped mode should never care about row-boundary crossings because they can't occur.
