TOM的GTM_FIXED_CLOCK_0~GTM_FIXED_CLOCK_4 怎么选 Level 2 User22516 Level 2 需要在EB配置里配置MCAL的MCU中的GTM下的TOM产生1ms的定时,TOM_0和TOM_1中的通道可以任意选吗,以及GTM_FIXED_CLOCK_0~GTM_FIXED_CLOCK_4怎么选? Like 回复 订阅 十月 28, 2021 12:02 AM 877...

通过前面计算我们得出FXU的输入时钟为50MHz,如果我们选择FIXED_CLOCK1,分频2的4次方为16分频,那么频率为3.125MHz,根据公式: 那我们的TICK最小为3.125*10^6,65535是肯定不够的。通过计算选择FIXED_CLOCK2也是不够的,因此我们选择FIXED_CLOCK3,分频为2的12次方,通过计算得出FIXED_CLOCK3时钟频率为50MHz/2^12=12207...
2.然后我们回到MCU->GtmGlobalConfiguration_0->General,这里有两个参数,就是上文中决定全局分频GLOBALDIV的GCLK_NUM和GCLK_DEN,这里一般都配置成1,也就是全局1比1分频。3.然后下面有一个FixedClock配置,前面提到因为FXU是不可配置分频的,但是可以配置时钟源和开关,就是下面这两个配置参数。
