C8051F060 外设ADC2程序.测量一个外部电压,并通过串口和终端打印功能将测量结果传到计算机windows终端.-This program measures the voltage on an external ADC input and prints the

result to a terminal window via the UART.

The system is clocked using the internal 24.5MHz oscillator.　

Results are printed to the UART from a loop with the rate set by a delay

based on Timer 2.　This loop periodically reads the ADC value from a global

variable, Result.

The ADC makes repeated measurements at a rate determined by SAMPLE_RATE

using Timer 3. The end of each ADC conversion initiates an interrupt which

calls an averaging function.
