STM32F4 SPI3无法通信，发现和JTAG复用，如何切换JTAG到SWD

wjlenergetic · 发表于 2015-2-5 19:34:42

看DATAsheet，是这样说明的：
This sequence is:
1. Send more than 50 TCK cycles with TMS (SWDIO) =1
2. Send the 16-bit sequence on TMS (SWDIO) = 0111100111100111 (MSB transmitted
first)
3. Send more than 50 TCK cycles with TMS (SWDIO) =1

具体应该怎么操作？？求大神

GPIO_PinRemapConfig(GPIO_Remap_SWJ_JTAGDisable,ENABLE);
