如果有自己的工程,直接从
LiteOS源码获取
开始关于STM32CubeMX的安装,看我另一篇博客STM32CubeMX安装
GPIO这里配置PF9,因为我的开发板上这个引脚接的是LED灯
这里根据原理图,设置默认高电平,推挽输出,命名为LED0
二者的区别
在keil中打开,编译运行,无错误、无警告,表示创建成功
在刚才创建的工程目录下创建LiteOS
文件夹,将刚才下载的文件里面的四个文件夹拉到里面
需要添加的文件都在arch\arm\arm-m路径下
LiteOS/arch
分组arch\arm\arm-m\src 目录下的全部文件
los_hw.c
los_hw_tick.c
los_hwi.c
arch\arm\arm-m\cortex-m4\keil 目录下的:(注:根据芯片内核选cortex-m文件夹)
los_dispatch_keil.S
在添加文件时,需要将文件类型选择为所以类型
LiteOS/kernel
分组kernel\base\core 文件夹下全部.c文件
los_priqueue.c
los_swtmr.c
los_sys.c
los_task.c
los_tick.c
los_timeslice.c
kernel\base\ipc 文件夹下全部.c文件
los_event.c
los_mux.c
los_queue.c
los_sem.c
kernel\base\mem\bestfit_little 文件夹下全部.c文件
los_heap.c
los_memory.c
los_membox.c
los_memcheck.c
kernel\base\mem\common 文件夹下全部.c文件
los_memstat.c
los_slab.c
los_slabmem.c
kernel\base\misc 文件夹下全部.c文件
los_misc.c
kernel\base\om 文件夹下全部.c文件
los_err.c
kernel\extended\tickless 文件夹下全部.c文件
los_tickless.c
kernel 文件夹下的
los_init.c
LiteOS/config
分组target_config.h
文件LiteOS/cmsis
分组tcmsis_liteos.c
文件../LiteOS/arch/arm/arm-m/include
../LiteOS/kernel/include
../LiteOS/kernel/base/include
../LiteOS/kernel/extended/include
../LiteOS/OS_CONFIG
../LiteOS/cmsis
../LiteOS/cmsis/1.0
../LiteOS/cmsis/2.0
../LiteOS/cmsis/include
下面所以操作均在target_config.h中进行
BOARD_SRAM_START_ADDR
定义内存的起始地址,内存是 RAM(运行)内存,STM32 的 RAM起始地址是 0x20000000。如果不知道 RAM 的起始地址,可以在工程中查看BOARD_SRAM_SIZE_KB
定义芯片 RAM 的大小,根据对应的芯片进行修改,比如STM32F103ZET6 的 RAM 是 64KB,那么 BOARD_SRAM_SIZE_KB 可以定义为不超过64K,当然一般不能定义到那么大的,因为工程本身也是使用了一些内存的,系统可管理的内存大小就要小一点,根据需要进行调整即可。这个文件需要根据不同的板子来找,一般都是stm32f?xx it.c【?是芯片型号】
屏蔽掉PendSV_Handler
和SysTick_Handler
在设置里面勾选Use MicroLIB
