ADC reference for STM32WL31 VBAT measurement
Good day,I want to measure the VBAT voltage of a STM32WL31 using its ADC. I setup the ADC channel as follows using the ST HAL driver:ADC_ChannelConfTypeDef ConfigChannel = {0}; ConfigChannel.Channel = ADC_CHANNEL_VBAT; ConfigChannel.Rank = ADC_RANK_1...
STM32Cube FW_WL V1.5.0
I upgrade my project recently to the above firmware (STM32Cube FW_WL V1.5.0) which ended up not working.Lots of errors, I think mostly because of the introduction of the relay node.After a couple of days trying to get this working I started a fresh ...
