全球首發，使用hal庫Proteus 仿真stm32f103實現跑馬燈

由于3.5的庫，Proteus 支持不太好，開始轉向hal庫。

#include "led.h"
void LED_Init(void)
{
GPIO_InitTypeDef GPIO_Initure;
__HAL_RCC_GPIOA_CLK_ENABLE(); //開啟GPIOA時鐘
__HAL_RCC_GPIOD_CLK_ENABLE(); //開啟GPIOD時鐘
GPIO_Initure.Pin=GPIO_PIN_8; //PB5
GPIO_Initure.Mode=GPIO_MODE_OUTPUT_PP; //推挽輸出
GPIO_Initure.Pull=GPIO_PULLUP; //上拉
GPIO_Initure.Speed=GPIO_SPEED_HIGH; //高速
HAL_GPIO_Init(GPIOA,&GPIO_Initure);
GPIO_Initure.Pin=GPIO_PIN_2; //PE5
HAL_GPIO_Init(GPIOD,&GPIO_Initure);
HAL_GPIO_WritePin(GPIOA,GPIO_PIN_8,GPIO_PIN_SET); //PA8置1，默認初始化后燈滅
HAL_GPIO_WritePin(GPIOD,GPIO_PIN_2,GPIO_PIN_SET); //PD2置1，默認初始化后燈滅
}
