28377D 怎么设置双核分别驱动各自的pwm以及采集各自的采样值？

目前想要用cpu1用epwm3，同时adca到dacd的channel0采集信号（由epwm3SOCA触发，ADCINT1发送中断），作比较后根据情况触发cpu2的采样（adca到adcb的1通道，由epwm2SOCA触发，ADCINT2发送中断）和epwm2。

目前运行，每个pwm都是给定50%定值输出，给定的采样值也是让cpu2恒定触发采样和epwm2。cpu1的epwm3没有输出，但是由它触发的adca到adcd的零通道是有采集数据的。cpu2的epwm2没有输出，相应的adc1也没有采集。求助

Green Deng：

一个是，你的问题关键似乎在于ePWM3没有发波但ADCxIN0的通道采样被触发了。这里不知道是你的PWM设置有误（看不到这部分代码）还是你的PWM引脚测错了？
二是你的程序中似乎没有配置将ADC的owner ship分配给CPU2的CPUSEL11寄存器？

第一个问题，引脚没有测错，因为用了另一个程序同一个引脚输出epwm，是可以输出的。cpu1的pwm和adc的设置如下，请问那些地方有错误？

第二个问题我不是很清楚，cpu1也要用到adca，adcb，adcc，adcd。如果把adca和adcb的ownership分给cpu2。那不是cpu1用不了adca和adcb了吗？28377d的每一个adc通道只能由一个cpu来控制采样？
