TI中文支持网本人初用TM4系列微处理器，拿TM4C123GE6PZ芯片做32路PWM输出时，有5路工作异常（没有输出），分别是PD7、PF0、PG3、PJ0和PJ1。
现在我知道了PD0和PF7不能用是因为他们具备NMI中断功能，设置他们需要开锁。但是PG3、PJ0和PJ1呢，他们也需要开锁吗？也有很特殊的功能吗？实际上我把PG0、PG1、PG2、PG3都用了，只有PG3工作异常，它与另外三个引脚相比哪里特殊了？
非常感谢！

PG3 PJ0 PJ1不需要进行特殊的配置。
请问你是使用Timer输出的PWM么？能否将相关配置的代码贴出来。谢谢

楼主，
建议你把和这些管脚相关的配置代码上传一下，这样比较容易分析问题。
谢谢
