MSP430G2553的代码，可给430G2X系列参考，有ADC10多通道多次采样，TIMER定时中断，TIMER的PWM输出，UART的初始化、ASCII码输出、接收中断。 特别是ADC10的多通道多次采样，很多同学刚开始学430不会用，一定记得要用数组接收数据，代码中用的ADC[0~4]接收的数据。 用ADC多通道多次采样，特别需要注意的是，如果你要采集通道 4 5 6 7（也就是P1.4~7），你还是得设置ADC10DTC1=8；，如果设置成4就会错误。 但是可以 ADC10AE0|=BIT4+BIT5+BIT6+BIT7；（不使能P1.0~3的ADC功能） 同时ADC10CTL1起始位置还是设置INCH_7；-MSP430G2553 code, can refer to 430G2X series, there are several multi-channel ADC10 sampling, TIMER timer interrupt, TIMER PWM output, initialize the UART, ASCII code output, receive interrupt. Especially multi-channel ADC10 multiple sampling, many students just beginning to learn 430 will not use, must remember to use an array to receive data, ADC code using the received data [0-4]. Multi-channel ADC with multiple sampling, particular note is that if you want to capture channel 4567 (that is, P1.4 ~ 7), you still have to set ADC10DTC1 = 8 , if an error is set to 4. But can ADC10AE0 | = BIT4+BIT5+BIT6+BIT7　(ADC function is not enabled P1.0 ~ 3 in) while ADC10CTL1 starting position is set INCH_7
