從零開始點(diǎn)亮CW32L052的LED燈

?1. 創(chuàng)建工程文件夾，并賦予可讀可寫權(quán)限：

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

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

2. 初始化git倉庫，以便同步到遠(yuǎn)程創(chuàng)庫：進(jìn)入剛進(jìn)入的文件夾，執(zhí)行g(shù)it init 并用git config --global user.name "name", git config --global user.email "email@qq.com"

lugl@lugl-virtual-machine:~/cw32l052_pro$ git init
已初始化空的 Git 倉庫于 /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 "name@qq.com"

3. 在gitee上新一個創(chuàng)庫，并下載一下倉庫：

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

remote: Counting objects: 100% (9/9), done.

展開對象中: 100% (9/9), 6.91 KiB | 6.91 MiB/s, 完成.

4. 把cw32l052的gcc工程模塊復(fù)制進(jìn)cw32l052_pro/cw32l052文件下
5. git add . 以及git commit 同時把push到遠(yuǎn)程倉庫

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

6. 用vscode 打開工程文件夾

?
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);
    // 開啟兩線調(diào)試接口
    RCC_SWDIO_Config(RCC_SYSCTRL_SWDIOEN);

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


    }

    return 0;
}

9. 接上cw_link，并執(zhí)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]

這樣我們就可以看到開發(fā)板的LED在閃爍了。
