系列开坑，红牛开发板的厂家例程都是使用标准库3.5开发的。旺宝的lpc教程写的很详细，但是stm的就没啥资料，貌似厂家也收摊不玩了。我参考野火跟硬石的教程。看他的电路图。试图把他的例子都用stmcubeMX重写一遍，并参考零知开发板例子。给红牛开发板也使用arduino连接外设。。今天先移植gpio。移植原则，尽量跟原来的标准库类似，只把标准库的外设设置一类的用自动生成的hal函数代替。
旺宝-红牛-流水灯演示实验
电路解析：五个用户 LED 灯D1-D5,，接在PF6-PF7上。
新建一个stmCUBE工程。
选择103zet。配置外置晶振。
设置时钟树，跑在72M上
配置gpio 这里可以给引脚起名字 user label
工程选项，这里生成keil的工程，我这里版本是5.1。注意文件夹不要有中文。
。
这里选拷贝所有库，给每个外设独立生成一个。c。h文件
这就生成了一个keil工程，用keil打开 可以看到自动生成了gpio的设置代码
剩下的就是在
/* USER CODE BEGIN 1 */
/* USER CODE END 1 */ 里填写用户代码。只有在里边写的代码不会被cubeMX给重新生成代码时候自动重写。这里尽量照搬红牛厂家的原来程序。可以用hal标准函数代替的就用hal代替。
原来自定义的延时函数
void Delay(uint32_t Time)
{
uint32_t i;
i = 0;
while (Time--)
{
for (i = 0; i < 8000; i++);
}
}
用HAL_Delay()代替
翻转io LED_GPIO_PORT->ODR ^= LED1_GPIO_PIN；用 HAL_GPIO_TogglePin(LED1_GPIO_Port, LED1_Pin);代替
这里是修改过的文件 。修改了main.c gpio.c gpio.h
