单片机实现的USB转JTAG调试器

本项目旨在实现一个USB转JTAG调试器,使用的是C++.但是由于嵌入式条件限制,仅仅使用了C with Class功能。


1.类IJtagPort是用GPIO模拟JTAG时序用到的最低级的类,JTAG这一部分只需要移植这个类。 2.Stm32F103JtagPortImpl是在单片机STM32F103上的IJtagPort实现。 3.IJtagPort会被Jtag调用,Jtag将会实现JTAG时序,并提供一些API接口。 4.UsbJtagBridge是连接USB和JTAG的类,也就是说Jtag是可以单独使用的,可以直接调用Jtag的API,通常者用来测试JTAG时序。UsbJtagBridgeCmd.h是USB和JTAG交互的命令,当USB接收到数据后,通过调用UsbJtagBridge的接口API,然后会激活UsbJtagBridgeTask任务,该任务会查询当前所支持的IJtagService接口的子类,进而调用接口子类的ServerProcessRequest方法,达到执行JTAG的功能。
