Description: 3. A/D circuit simulation program design and the external voltage through the AD sampling, and then come back using the SPI interface of the sampling data show, and the conversion results sent to the host computer via the UART for display. First set the array needs to be displayed, use PINSEL0, PINSEL1 register set the serial port 0, use the control port IO0DIR set 74HC595, initialize the serial port 0, use U0LCR, U0DLM, U0DLL, U0LCR register set the baud rate, initializing the SPI interface, set SPI clock frequency, interface mode. Second, the ADC module settings, through the shift register ADCR select channel 0 setting, set the conversion clock, use software to convert, use the clock conversion, down conversion mode for non-operating mode, non-test mode, direct start ADC conversion, the use of pin falling edge trigger ADC conversion, read the ADC result and clears the DONE flag, switch channels and make the first conversion, waiting for the end of conversion, and then start the co
