Summary: I am sampling the internal voltage reference 5 times using DMA with the ADC set to continuous mode with LL_DMA_LIMITED. I know about the errata that says to ignore the first ADC value, but the other 4 values only become consistent if I use a...

If you give pyocd an object file, like an Intel `.hex` file or an ELF file, it can figure out at which addresses to write automatically. When using a binary file, you need to supply a base address manually. Take a look at the help output of `pyocd fl...

Sometimes an STLink is able to identify the chip it is connected to, and sometimes not. I think it only works for STLinks that are embedded into a dev board, like one of the Nucleo boards.For instance, I have an NUG431KB Nucleo board. When I plug it ...

In what way do you want to combine the use of the advanced timers and the HR timers? If you look at the “external events mapping�? section of the RM0440 Rev 7 document on page 843, you can see maybe other timers’ TRIGO can be used to synchronize the ...
