Forum: System Workbench for STM32

Posted by ece on 2018-10-08 03:11

Hello!

Been coding for STM32 for a couple of month now but I’m still a new beginner at the best.

I have one question that I know all you gurus can answer. I’m about to implement a CRC check of the flash, due to requirements, and the first thing I read about the CRC is that the RCC clock peripheral needs to be active:
“1. Enable the DMA peripheral clock via the RCC peripheral.”

Now it is like this that I use the I2C and therefore are prohibitted from activating the RCC in CubeMX.
Does that mean that I’m smoked?

Thanks in advance!
