I'm trying to minimize the current consumption of an STM32G031K but I can't reach the ones calculated by the STM32CubeMX in any way. I tried with Low Power Sleep Mode, Stop Mode 0 and Stop mode 1. In Stop Mode 1, according to STM32CubeMX I should hav...

Please confirm that the scope probe alligator clip was connected to gnd very close to the point you had placed the probe tip. Large probe ground loops may lead in false detection of noise and over/undershoot behaviours (ringing), The probe should be ...

While this microphone has decent PSR (Power supply rejection), you may have a lot of power supply noise, which should be filtered out. You should check the power supply with an oscilloscope, possibly with FFT parsing if it is present.It could pick up...

I solved. The problem was due to the configuration of the pins.Configuring them all as analog inputs (except those used to generate the wake-up interrupt, which have been configured as input+EXTI), the consumption dropped below 3uA.Attention should b...

Turn-on time should be not greater than 10ms, but you can check it by introducing a HAL_Delay(50) in main, just after HAL_Init() and hardware initialization.As the signal is initially saturated at bottom, then at top and then at bottom again, look wi...
