[M0] TM10 CKO输出波形例程

看了官方的主要函数是:
#define Simple_CKO_MainCounter    120
#define Simple_CKO_Prescaler    100
#define Simple_CKO_Source          1

}
再看手册的对应输出口

再贴上整个程序  编译后烧录示波器没有测试没有波形输出。

GPIO口有使能输出吗？

你使能输出的功能复用是复用的什么功能，你直接点击回复我吧，不然我收不到提醒很容易看不到你回复，另外我自己测试了一下，是没问题的，我的猜测就是你使能GPIO的功能复用不对，GPIO的功能应该是TM10_ClockOut

还是不行

PINX_InitStruct.PINX_Alternate_Function = 5; //这儿你要改成4，alternate function是从0开始算的，5是TIM16_TRGO，4才是TIM10 CKO。

已经弄好了，原来如此。感谢。。
