28069 ADC触发中断问题

Kancheng Huang
Prodigy 90 points


在Lab5b的基础上更改了部分代码，期望实现双路驱动。用的是28069Launchpad+2 * 8301 RevB。

现在发现更改设置ADC中断后，就完全无法触发中断了。不知道是哪里有问题。

void HAL_setupAdcs(HAL_Handle handle){
....
  // configure the interrupt sources
  ADC_disableInt(obj->adcHandle,ADC_IntNumber_1);
  ADC_setIntMode(obj->adcHandle,ADC_IntNumber_1,ADC_IntMode_ClearFlag);
  ADC_setIntSrc(obj->adcHandle,ADC_IntNumber_1,ADC_IntSrc_EOC7);

这里将 EOC7改为 E0C14，因为实际上是希望两路同时在跑。所以就把触发放到第二路最后一个SOC14完成。

结果在就无法触发中断了，因为观测变量可以看到，Ctrl State卡在 Offline，那个计数counter一直停留在0. 其余代码不变，改回7就可以正常驱动J1那一路。

整体代码更改了很多，但是基本上就是把原版区分J1 J5的地方，重新更改为两部分都DEFINE，ADC的setting里面，J5的SOC为7~14。总感觉是漏过了某处的设置导致的。

    附上我的SetupADC的Function，基本上没有做太多更改，主要是现在把J1 J5用到的A

    你配置了不同的ADC触发源，检查一下PWM初始化部分有没有设置EPWM4 SOCA。

    楼上说的对估计是PWM4 ADCSOCA的信号没有发出来。

    后来修改了触发源，的确正常驱动了。谢谢。

    在 hal.c文件里面。
