STM32 Timer-Triggered ADC Sampling with DMA for FFT Analysis

Signal Analysis Parameters To analyze a signal using FFT, several key parameters must be defined: Target signal frequency: f Target signal period: T = 1/f Sampling frequency: fs Sampling period: Ts = 1/fs Total sample points: NPT Total sampling time: t = NPT × Ts Frequency resolution: f0 = fs/NPT Ca...

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...
