请问我已经正确设置了我的AdCON/安塞尔寄存器吗？

嗨，黑帮，有人能看看我的简短代码，并告诉我是否我已经设置了我的AdCON/安塞尔寄存器正确。我已经有一段时间了，似乎不太清楚我出了什么问题。我期待在两个LED的输出事件发生时，但我没有得到输出。我想知道逻辑是错误的还是我的设置是错误的。感谢任何输入！

    Hi gang,

Can someone look over my brief code and give me an idea of whether I have setup my ADCON/ANSEL registers properly. I have been at it for a bit and can't quite seem to figure out where I am going wrong. I am expecting output on two LED's when events occur, but I am getting no output. I am wondering if the logic is incorrect or if my setup is wrong. Thanks in advance for any input!
