谢谢!
我的理解是
互感器 200变成5
单片机 5变成200 并显示
对吗?

iar中make和compile 的原意如下
make:Brings the current build configuration up to date by compiling, assembling, and linking only the files that have changed since the last build.
Compiles :Compiles or assembles the currently selected file, files, or group.
One or more files can be selected in the Workspace window—all files in the same project, but not necessarily in the same group. You can also select the editor window containing the file you want to compile. The Compile command is only enabled if every file in the selection is individually suitable for the command. You can also select a group, in which case the command is applied to each file in the group (including inside nested groups) that can be compiled, even if the group contains files that cannot be compiled, such as header files.
麻烦能否解释一下?

我编单片机程序
1、方式1 :1位起始位,8位数据位,1位停止位=10位。 也就是1帧要2byte?
2、方式2 :1位起始位,8位数据位,1偶校验位,1位停止位=11位? 这1位偶校验有用?
我可以编程用crc来 校验8位数据,从而代替偶校验?
如此说来,方式1 可以代替方式2,方式2没什么大用 吧。
3、能否介绍一下用pca的 io口模拟串口,为什么用到pca中断和外部中断?
谢谢!!!
