A waveform generator using DAC on STM32F4Discovery is build. Connecting the generator output to an ADC input, the waveform may be visualized via USART on the PC by a LabView virtual instrument using VISA. Both direct conversions and DMA conversions are presented. The USB to TTL adapter used is CH340, which worked well even at 921600 bps.
