Important parameter

In the file include/yang_config.h in

If the resolution is too high , take Yang_isEmbbed Set to 0

  compile

Compile the script ：cmake_mips32.sh

  Can be libimp.a Wait for a change libmip.so, Reduce program volume .

demo The use of glib library , If you use ulib library , You can replace the above class library .

Hard coded code

 All chips need to be hard coded yangipc/YangIpcEncoder.h
