Through the preparation process so that D/A converter DAC0832 sawtooth generated, and then use A/D converter ADC0809 conversion of the waveform acquisition. ADC0809 which the clock signal provided by timer 8253 interruption of the application by A/D converter after a signal to the 8259A, 8259A and then sent to the interruption of the application processor 8086 signals the completion of the acquisition of the sawtooth
