I used a 10A, 27.6V switching power supply to connect several detectors through cables. The detectors used switching power supply chips to convert to 5V to power the microcontroller and other things (...
I am learning ARM2119. Can you give me an example of how to read and write FLASH? Is there any reference book? Thank you! My email address is hunanchangde_wei@sohu.com...
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...
