基于AT32F413RCT6移植uC-OS3(有问题欢迎指正)

前情提要 #IAR #ARM-Corte-M #ARMv7-M
从思路入手 ->配置 ->接口 ->源文件
RealTime ->时基->systick
以下操作部分参考自Internet

所需文件

• ***完整IAR工程文件
• ***uC-OS3-3.08.02 Github下载
• ***uC-LIB-develop Github下载
• ***uC-CPU-develop Github下载

在工程目录新建UC-OS3文件

简单修改文件名 放进刚下载的3个文件

bsp_cpu.c 在\uC-CPU\BSP\Template
bsp_os_dt.c 在\uC-OS3\Template
cpu_a.asm 在\uC-CPU\ARM-Cortex-M\ARMv7-M\IAR
cpu_c.c 在\uC-CPU\ARM-Cortex-M\ARMv7-M
cpu_core.c 在\uC-OS3\uC-CPU
lib_ascii.c lib_math.c lib_mem.c lib_str.c 都在\uC-OS3\uC-LIB

os_app_hooks.c 在\uC-OS3\Cfg\Template
其他.c文件都在 \uC-OS3\Source
在Options快捷键选择工程按下alt+F7->C/C++ Compiler->Preprocesser中添加路径

$PROJ_DIR$\uC-OS3\uC-CPU\Cfg\Template
$PROJ_DIR$\uC-OS3\uC-CPU\ARM-Cortex-M\ARMv7-M\IAR
$PROJ_DIR$\uC-OS3\uC-CPU
$PROJ_DIR$\uC-OS3\uC-LIB\Cfg\Template
$PROJ_DIR$\uC-OS3\uC-LIB
$PROJ_DIR$\uC-OS3\uC-OS3\Cfg\Template
$PROJ_DIR$\uC-OS3\uC-OS3\Ports\ARM-Cortex-M\ARMv7-M\IAR
$PROJ_DIR$\uC-OS3\uC-OS3\Source

修改配置文件
cpu-cfg.h 使能32位时间戳

使能前导码0等待

使用中断分组4

os_cfg_app.h

修改启动文件 startup_at32f413.s
