SPI接口实险，LED数据管显示。
1、程序通过SPI接口输出数据到HC595芯片驱动LED数据管简单显示。
2、内部1 M晶振，程序采用单任务方式，软件延时。
3、进行此实验请插上JP1的所有8个短路块，JP6(SPI_EN)短路块。-SPI interface is dangerous, LED data display. 1, the program output data through the SPI interface to the HC595 chip data-driven pipe a simple LED display. 2, within 1 M crystal, single-task approach procedures, software delay. 3, to carry out this experiment JP1 plug in all the eight short pieces, JP6 (SPI_EN) short-circuit block.
