1. GPIO工程代码分析不管东西南北，万事皆可电灯，所以从GPIO开始做起，不过，代码实在是太太简单明了。#include "main.h"
#include "user_init.h"
int main(void)
{
MF_Clock_Init();
MF_SystemClock_Config();
FL_Init();
MF_Config_Init();
UserInit();
while(1)
{
LED0_TOG();
FL_DelayMs(5000);
}
}初始化包括，时钟，板卡，配置和用户自定义，然后就是循环， LED0_TOG();
FL_DelayMs(5000);问题就是没有API代码导则，这个肿么整。那么其实还是来自厂家的定义文档， #define LED0_TOG()FL_GPIO_ToggleOutputPin(LED0_GPIO, LED0_PIN)文件的还是都是来自如下#include "fm33lg0xx_fl.h"http://bbs.eeworld.com.cn/data/attachment/forum/202111/26/100147kx77nvma0srmvd4v.png.thumb.jpg
2. 项目的编译点击编译，可以直接开始编译，顺利通过。http://bbs.eeworld.com.cn/data/attachment/forum/202111/26/100304ev96291bnv19x4hx.png.thumb.jpg
3. 代码下载这个板子如果空白的芯片没有焊上，应该就是一个各个引脚引出的裸板，需要自备调试器去下载。经测试，以下各款老爷调试器都可用，一个是jlink7.0，一个是jlink8.0，看来是芯片没有验证和加锁的流程，其中jlink OB款是限制在厂家用的公版，用起来也不错。http://bbs.eeworld.com.cn/data/attachment/forum/202111/26/101431b6pp211aetitkahh.jpg.thumb.jpg
采用SW下载，只需要2根SWO和SCK，分别是数据和时钟下，如下连接。下载的时候，还需要一个reset键置位，下载过程中提示有这个问题，但是没有点reset也顺利下载了。

按照上面的说明，如果下载器如果没有专门的下载键，按一下reset就可以了。原来的delay延时是1秒，1000ms，改成200ms快闪模式还比较顺利，就是有点太闪亮了。http://bbs.eeworld.com.cn/data/attachment/forum/202111/26/102603e5lx9ep8dpp4ui4j.gif
