FPGA串口通讯例程，经我修改绝对可用； 默认48M,9600-8-1/2，如果时钟不同只需修改时钟分频数即可。-The FPGA serial interface communication by the modified routine, absolute can be used The default 48 M, 9600-8-1/2, if the clock different modify it only clock points frequency can.

这个程序是C8051F30x设备通过 spi 通讯然后从串口发送的例程 具有 spi 跟串口的初始化操作-This program sets up the GPIO pins on the C8051F30x device for the correct functionality, then uses the SPI_Transfer function to send and receiveinformation through the SPI pins. As information
