 KL25 TPM模块一定要通过触发才能开始计时吗

配置你需要中断的时间，开启中断。每次触发以后就是你需要的时间间隔。

FSL_FAE_ConstYu

当然你也可以选择一旦使能就立即开始触发，CSOT寄存器=0，如果选择一个外部（相对于TPM）输入的触发源通过TRGSEL寄存器设置选择PIT/TPM/CMP/RTC等的来设置触发。我猜你想说的是前者，相当于软件触发。

这些我都做了，我的意思是启动TPM是否要依靠触发的方式，因为我将TPM使能后，它好像没有工作，这是我的代码
OSC0_CR |= OSC_CR_ERCLKEN_MASK;         // Enable OSCERCLK of OSC Module 
  /* Enable TPM1 clock control */
  SIM_SCGC6 |= SIM_SCGC6_TPM1_MASK;
SIM_SOPT2 |= SIM_SOPT2_TPMSRC(2);          // OSCERCLK as TPM clock source
TPM1_MOD = 0x1f40;                    // T=1ms
TPM1_SC |= TPM_SC_CMOD(2) | TPM_SC_TOIE_MASK;    /* TPM counter increments on every TPM counter clock,Enable Timer Overflow interrupt */
enable_irq(FTM1_irq_no);

 

FSL_TICS_MAHUI

 TPM是不需要外部触发也可以工作的，你可以使用Processor Expert生成相应的代码，只要时钟有效并且在TPM_SC[CMOD] bits配置为0b01, 并且TPM_CONF [CSOT]bit 配置为0，计数器可以开始计数。
祝顺利。

请问你的这个Processor Expert工具在那里下的啊？是FreeScale自己的那个什么code....编译器里的吗？

现在好了，我把CMOD位不小心设为2了，谢谢各位的指导！

 Processor Expert工具是内嵌在CodeWarrior开发工具中的。
飞思卡尔还提供独立版的Processor Expert工具，产生的代码可以用在IAR和Keil开发软件中。

         TPM模块可以实现脉冲计数吗？用来计编码器的值？
