先简单记录下安装：
1. 安装 sourcery工具链或 keil都行
安装python 和 scons：
配置这些工具路径以及RT-Thread源码路径RTT_ROOT，添加到环境变量
2. 开始编译 bsp\stm32f10x工程，在编译以前需要稍微修改如下几个文件
rtconfig.py 此文件必须修改
rtconfig.h 此文件用于裁剪rt-thread（根据需要修改）
比如使用 keil工具来编译：
修改rtconfig.py,
CROSS_TOOL=‘keil‘
EXEC_PATH=‘D:\Keil_v5‘
cmd命令行 cd到bsp\stm32f10x：
D:\rt-thread\bsp\stm32f10x>scons
即可在 bsp\stm32f10x路径下生成 axf文件和bin文件
scons -c 清除编译出来的文件，如.o
scons -j4 多线程编译，2个线程/每个CPU核
主要在 rt-thread-v2.0.0\bsp\stm32f10x\ 下的文件进行修改和添加：
drivers\SConscript 添加驱动文件，
# add the general drivers.
src = Split("""
board.c
stm32f10x_it.c
led.c
LCD5110.c
sys.c
ds18b20.c
usart.c
""")
这些基本的驱动文件里的延时需要调试下。
其他文件不用怎么改，接下来在 applications\application.c 中创建自己的线程函数了，实现相关功能。

这些线程时间片和每个线程中的延时根据需要调整，不然出现屏幕显示异常。^_^
