# Sources for compiling a lib devoted to use Serial port 3-pins of CG10/20/50

just run `make` in the root directory of the project.
it will produce the library `libserial.a`

installation into the right compiler folder is not automatic.

So you need to copy `libserial.a` in the lib folder of sh-elf-gcc compiler
and the file `include/serial.h` into the include directory

`make clean` cleans all the `.o` and the library from the sources folders.
