另外SDCC、IAR的要选8bit烧录
我晚上回去试试。

sdcc一定要选8位吗？你咋知道的呢？ 好厉害哦。

{:4_198:}SDCC就是51的编译器嘛
收藏学习
谢谢分享！
大佬，官方的AI8051U.H里面 有c51的语法，像下面这个unsigned char volatile far 这个在sdcc里面对应的是啥，你知道不？
是不是__sfr __at(0x7efeb0) PWMA_ETRPS？好像不对。会报地址超出的问题。

你看我发的源码里搜下，对应这个：

刚刚重新看了一下。我知道了。多谢。
我往你的工程里加了一个红外的，直接把你的工程搞崩了。 {:ciya:}{:hanxiao:}
