Resolved! ADC measurement error on STM32G030KxTx

I am developing a project to take some measurements with ADC channels, however the values are wrong. When I connect any ADC channel direct to GND, it gives me a value about 60~80 (The ADCs are 12-bit precision) and this error propagates for any readi...

STM32G4 series fastest way to add 32 16bit signed integers

I have the following function to sum 32 16bit signed integers as optimally as I think is possible:int16_t sum32elements2(int16_t vals[]) { uint32_t s1 = __SADD16(*(uint32_t*)&vals[0], *(uint32_t*)&vals[2]); uint32_t s2 = __SADD16(*(uint32_t*)&val...

What is the startup time of PVD?

I want to use the PVD function of my STM32U5(but I think this applies to nearly all STM32s) to detect when my supply voltage goes over(!) a specific threshold. But it might already be there when I enable PVD. Since this means looking for a zero on PV...
