I'm using a STM32F070CBT and putting it to stop mode with low power regulator on and waking it up with GPIO events.In our project, we're using every single pin from the MCU, most of those are timers and GPIOs, NFC tag reader, etcAfter waking it up, w...

Hello guys,I'm using a STM32F070CBT MCU and I need to put it in Stop Mode and wake him up second by second. Looking at the datasheet, I noticed I couldn't use I2C as a wake-up source, and the easiest way to do it would be using GPIO.We've tried to us...
