experiment equipment: stm32F103 C8T6 Purpose: ADC real-time sampling shows waveforms through an anonymous host computer (virtual oscilloscope) ADC1 and serial 1 dual DMA use to speed up the transfer rate Hardware resources: 1, ADC1 channel 1 (peripheral A1) 2, serial port 1 (baud rate: 500000) Experimental phenomena: The anonymous host computer displays the waveform in real time. The sampling frequency of the ADC is about 1Mhz (the highest value of the single ADC mode has been reached, but the maximum transmission rate of the host computer is about 500000 baud. And only one byte per transfer of 14 bytes is valid (caused by the anonymous transfer protocol). It takes about 2.8ms to transfer once.
