STM32 HAL ADC: configuration, sampling strategies, and data movement with polling, interrupts, and DMA
1. Fundamentals ADC converts an analog voltage into a digital code. Resolution defines the number of quantization steps: 8-bit: 0–255 12-bit: 0–4095 (2^12 − 1) A single ADC controller typicallly multiplexes multiple input channels. When reading more than one channel, enable scanning or explicitly se...
