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:
http://www.rt-thread.org/phpbbforum
http://www.ourdev.cn/bbs
Where to get source code:
=========================
The rt-thread source code is maintained in google code
http://code.google.com/p/rt-thread/
use the following command to anonymously check out the latest source code:
svn checkout http://rt-thread.googlecode.com/svn/trunk/ rt-thread-read-only

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
