TFTP协议实现的源代码,拥有所有TFTP所需要的功能-This class provides all infrastructure for a performant file transfer protocol. It works in conjuction with the rootd daemon and can use parallel sockets to improve performance over fat pipes.

main.c已详尽注释连接的引脚 和 调试助手参数。STM32分别以串口,硬件SPI,模拟并口驱动CH395,4个socket连接, 原路返回上位机发送的数据。串口模式支持更改工作波特率，硬件SPI速率最高36MHz, 模拟并口较快，这三种模式支持在stm32任意型号下。(Main.c has commented on pins and debugging assistant parameters in detail. STM32 drives CH395 and 4 sockets by se
