Digital oscilloscope, the use of AD, DA and VGA three peripherals to achieve a simple oscilloscope, DA peripheral send sine wave to AD peripherals, AD peripherals resolved into digital signals, data sent to VGA peripherals for display. On the VGA, you can see the waveform, waveform, frequency and peak value of the waveform sent by the DA peripheral.
