So, what to expect from the 'C0?

As said, the 'C0 is mostly a cut-down 'G0. Let's now put aside the "is it a true STM8 replacement" and the price-related discussion, let's just have a look at what we can and what we can't find in these chips. I had a look at the DS and RM and here a...

HAL_SPI_Receive_DMA() won't start a transfer in a CubeMX project that I cloned. No activity on SPI bus. HAL call returns success. .IOC and generated files all compare successfully. (only changed some GPIO, SPI is configured same) What could I be missing ?

I simply wanted to make an identical program but with a different GPIO pinout. The SPI busses are all on the same pins and configured the same. What could I have touched that would cause the SPI transfer to not start ? I had to switch to HAL_SPI_Re...
