I am using the at89s52 microcontroller. Why is it that when my P3.2 port (used as external interrupt 0) is connected to an external circuit, the P3.2 port is high when the external circuit is at a hig...
wrote the simple makefile as above
The execution result was unexpected!
Why can't the command run in the shell, but run normally in the makefile?
Why does it return a '/'?
I would also like to ask all...
