Summary:

========

This directory contains the source code for M16C porting to rt-thread



two tasks is running:

led_task - blink the LED

finsh    - a user shell, comes with rt-thread



Where to get help:

==================

In case you have questions about, problems with or contributions for

Renesas M16C prot to rt-thread, you can send a mail to dzzxzz@gmail.com. 



or you can post a message to the rt-thread forum

there are two forums:

Build Project:

==============

there are two ways to build the renesase M16C project:

1,  install IAR Embedded Workbench for renesas m16c(recommend EWM16C-EV-3501.exe)

    Open Workspace rtt2m16c.eww by IAR directly

    rebuild all

    the target file(rtt2m16c.mot) will be produced in /rt-thread/bsp/m16c62p/Debug/Exe

    you can download the rtt2m16c.mot to m16c board with E8A

                   

2,  install python, scons and IAR for m16c(recommend python2.7, scons1.3.1 and EWM16C-EV-3501.exe)

    open a windows cmd, and change directory to m16c project, like /rt-thread/bsp/m16c62p/

    #set PATH=C:\Python27\Scripts;%PATH%

    #scons -c

    #scons -j 2



3,  crate IAR project with template project

    #set PATH=C:\Python27\Scripts;%PATH%

    #scons --target=iar -s

    add the context_iar.asm to M16C62P, and remove the context_iar.S
