如何让 VSCODE cpptools 支持 C51 (How to make VSCODE cpptools support C51)

It doesn't look like valid syntax. Is "interrupt" supposed to be an attribute? You can edit c_cpp_properties.json and add "interrupt=" and "INT_VECTOR_T0=" to the "defines" array.
Can you tell me what sfr and sbit are? Those are not types I recognize.

interrupt= 加入 "defines" 可以的，但 "INT_VECTOR_T0=" 还是不行。
( interrupt is OK，but "INT_VECTOR_T0=" not support.)
sfr 和 sbit 已经在 "defines" 中，所以不显示错误。
(Because it was added before, so no error is displayed.）

Sorry, My English is poor, but I will study hard.

I should have noticed sooner. C51 has some language extensions that our vscode extension does not support. I found it here: http://www.keil.com/support/man/docs/c51/c51_le_funcdecls.htm
Does this compile for you in C51? It is not valid syntax in C.

Thank you.

I used Keil compiled C51 Code.

Unfortunately, we have no plans to support C51 extensions at this time.
