用STM32实现读U盘的功能,基于KEIL4开发环境，可对16G的U盘进行读写。-use stm32 to read USB flash disk.

与PC的USB连接后，可以通过PC读写板上W25Q80BV的文件 （1M U盘功能） 驱动点阵屏 ST7565R 显示。-With the PC USB connection, you can read through the PC board W25Q80BV file (1M U disk function) drivers lattice screen ST7565R display.

ALIENTEK MINI STM32上调试通过的CH376程序，可以读出U盘厂商和容量，读写文件（寄存器版通过SPI接口实现）-CH376 program debugging through, you can read U disk manufacturers and capacity to read and write files on ALIENTEK MINI STM32 (register version via SPI interface)
