Refer the User Manual fo STM32L031 (see the ADCCLK and its prescaler ). Basic, general purpose and advanced STM32 timers. After the ADC conversion result is stored into the 16-bit ADC_DR data register (remember that the conversion result is 12-bit), then the …. Kindly give me suggestions to get rid from. Based on the overview of the temperature acquisition system, the hardware circuit design, ADC and DMA ….
