New possibilities for the ultra-low power segment!

STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...


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...
