STM32F103 implement ADC and DAC tracking
4.0
STM32F103RCT6 collection 2-channel analog signal, ADC1_IN2 and ADC1_IN3, is set to scan mode continuous ADC, uses DMA channel in the results array, an ADC is completed, then start the DAC conversion, realizes real-time tracking for two-channel ADC input signal and output measured to track 2 ADC/DAC 5KHz sine waves, no distortion , Of course you can adjust the speed to increase the tracking speed of the ADC conversion and increase the output frequency.
