Description: 用STC的MCU的SPI方式控制74HC595驱动8位数码管。
用户可以修改宏来选择时钟频率, 可以修改寄存器定义是STC12C5A60S2系列 还是 STC12C5628AD STC12C5410AD STC12C4052AD系列.
用户可以在显示函数里修改成共阴或共阳.推荐尽量使用共阴数码管.
显示效果为: 8个数码管循环显示0,1,2...,A,B..F,消隐.-STC MCU SPI control 74HC595 to drive eight digital tube. User can modify the macro to select the clock frequency, you can modify the register definitions STC12C5A60S2 series or STC12C5628AD STC12C5410AD STC12C4052AD series. Display function, the user can modify the common cathode or common anode. Recommended to make use of a common cathode digital tube display: 8 The digital control loop to display 0, 1, 2 ..., A, B.

Description: 3．A/D程序设计与电路仿真
通过AD对外部电压进行AD采样，然后利用SPI接口对采样回来的数据进行显示，并将转换结果通过UART发给上位机进行显示。
首先设置需要显示的数组，使用PINSEL0、PINSEL1寄存器设置串口0的连接端口，使用IO0DIR设置74HC595的控制口，初始化串口0，使用U0LCR、U0DLM、U0DLL、U0LCR寄存器设置波特率，初始化SPI接口，设置SPI的时钟分频、接口模式。
其次对ADC模块进行设置，通过移位设置寄存器ADCR选择通道0，设置转换时钟，利用软件进行转换操作，使用时钟转换，工作模式为非掉电转换模式、非测试模式、直接启动ADC转换，使用引脚下降沿触发ADC转换，读取ADC结果，并清除DONE标志位，切换通道并进行第一次转换，等待转换结束，然后再次启动转换，读取ADC的结果，从串口中输出结果，分别输出个位、十位、百位、千位数据。
-3. A/D circuit simulation program design and the external voltage through the AD 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

Description: 5. SPI程序设计与电路仿真
SPI是全双工的同步串行接口，一根SPI总线可以连接多个主机和多个从机，但是在同一时刻只允许有一个主机操作总线。在数据传输过程中，主机总是向从机发送一个字节的数据，而从机也是总是向主机发送1个字节数据（主机通过MISO接收数据）。
定义74HC595片选端口,通过PINSEL0、PINSEL1寄存器设置SPI引脚接口，通过设置IO0DIR驱动74HC595的接口，初始化SPI接口，发送显示数据，片选清零寄存器，等待SPIF置位，等待数据发送完毕。使用while循环，发送数据显示数据，运用延时程序使显示更加稳定易用。
-5. SPI program design and circuit simulation SPI is a full duplex synchronous serial interface, an SPI bus can connect multiple hosts and multiple slaves, but at the same time allowing only one host operating bus. During data transfer, the master to the slave always sends a byte of data, but also the slave always sends a byte to the host data (host via MISO receives data). Definition 74HC595 chip select port via PINSEL0, PINSEL1 register setting SPI pin interface, driven by setting IO0DIR 74HC595 interface to initialize the SPI interface to send display data, chip select register is cleared, waiting for SPIF bit waiting for data transmission is completed. Use a while loop to send data display data, using delay routine makes the display more stable and easy to use.
