从零开始点亮CW32L052的LED灯

​1. 创建工程文件夹，并赋予可读可写权限：

lugl@lugl-virtual-machine:~$ mkdir cw32l052_pro

lugl@lugl-virtual-machine:~$ chmod 777 -R cw32l052_pro/

2. 初始化git仓库，以便同步到远程创库：进入刚进入的文件夹，执行git init 并用git config --global user.name "name", git config --global user.email "[e-mail]"

lugl@lugl-virtual-machine:~/cw32l052_pro$ git init
已初始化空的 Git 仓库于 /home/lugl/cw32l052_pro/.git/
lugl@lugl-virtual-machine:~/cw32l052_pro$ git config --global user.mane "name"
lugl@lugl-virtual-machine:~/cw32l052_pro$ git config --global user.email "[e-mail]"

3. 在gitee上新一个创库，并下载一下仓库：

lugl@lugl-virtual-machine:~/cw32l052_pro$ git clone https://gitee.com/lugl/cw32l052.git
正克隆到 'cw32l052'...

4. 把cw32l052的gcc工程模块复制进cw32l052_pro/cw32l052文件下
5. git add . 以及git commit 同时把push到远程仓库

lugl@lugl-virtual-machine:~/cw32l052_pro/cw32l052$ git push

6. 用vscode 打开工程文件夹

​
7. make 一下：

lugl@lugl-virtual-machine:~/cw32l052_pro/cw32l052/cw32l052_gcc$ make
[DUMP]  build_exec/template.elf - > build_exec/template.s
[SIZE]  build_exec/template.elf
   text    data     bss     dec     hex filename
   1500      20    1572    3092     c14 build_exec/template.elf
-e Build Finish

8. 修改主程序如下：

static inline void LED_Init()
{
    GPIO_InitTypeDef GPIO_InitStruct;
    RCC_AHBPeriphClk_Enable(RCC_AHB_PERIPH_GPIOC, ENABLE);

    GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;
    GPIO_InitStruct.IT = GPIO_IT_NONE;
    GPIO_InitStruct.Pins = GPIO_PIN_10;
    GPIO_Init(CW_GPIOC, &GPIO_InitStruct);
}

int main(void)
{
    LED_Init();
    InitTick(24000000);
    // 开启两线调试接口
    RCC_SWDIO_Config(RCC_SYSCTRL_SWDIOEN);

    while (1)
    {
        GPIO_TogglePin(CW_GPIOC, GPIO_PIN_10);
        SysTickDelay(500);


    }

    return 0;
}

9. 接上cw_link，并执行 make flash:

lugl@lugl-virtual-machine:~/cw32l052_pro/cw32l052/cw32l052_gcc$ make flash
-e Start pyOCD
0000739 I Loading /home/lugl/cw32l052_pro/cw32l052/cw32l052_gcc/build_exec/template.elf [load_cmd]
[==================================================] 100%
0001348 I Erased 0 bytes (0 sectors), programmed 0 bytes (0 pages), skipped 1536 bytes (3 pages) at 2.47 kB/s [loader]

这样我们就可以看到开发板的LED在闪烁了。
