想用Tms470M的HET可以做脉宽信号检测，不知道该芯片能否实现。具体如何配置。
Hi lei,
TMS470的HET模块可以用于脉宽信号检测，你可以用PCNT指令来实现。
HET及其指令的具体用法请参考用户手册（TRM），链接：http://www.ti.com/litv/pdf/spnu495c

你好。能否给个例子。
Lm00 CNT { next= Lm01, reg = T, max= MAXC, irq = OFF,data=0}
Lm01 PCNT { brk=OFF,next=Lm00,irq=ON,type=RISE2RISE,pin=0}; // HET[0], period
上面两行就可以实现对输入脉冲周期的检测。
