We are working on a project which requires us to put our STM32L433 MCU's into a low power mode with memory retention(STOP2 mode). When measuring the IDD current draw on our NUCLEO-L433RC-P  in STOP2 mode, we found that at 1.8V VDD the current consump...

We are trying to implement the SPI interface on a STM32G070 MCU using DMA and no interrupts. MOSI MISO and SCLK all work fine, but the NSS signal does not behave the way we want it to. What we need is a precise change from 1 to 0 signaling the start ...
