STM32单片机的调试接口硬件电路

作者：时间：2016-11-10 来源：网络

如果要减小插座的数量，就用SWD模式的仿真，在这个模式下，如果用JLINK只要四根线就可以了，这四根线分别是：3.3V、GND、SWDIO、SWCLK

其中

STM32的JTMS/SWDIO接JTAG口的TMS；
STM32的JTCK/SWCLK接JTAG口的TCK。

SWD PIN 1------3.3V

PIN 4------GND

PIN7-------PA13(SWDIO)

PIN 9-------PA14(SWCLK)

如果要用ULINK2，则再加多一条“NRST”，即5条。
这个接口你可自行定义，在使用时用

杜邦线跳接或做块转换接口板联接仿真器与目标板即可。
