如何跑动STM32F411RE 【百科全说】

首先因为本地只能上内网，所以把IAR相关的软件和Licence破解之类的工具通过greenetrans传到本地，本地安装了半天。。。调试要代码吧要库吧，于是把代码打包，准备通过绿传传到本地，突然发现，被检测到是代码就给我rejected了。把代码压缩分卷成了好几份，Espace传给同事小伙伴，然后下线，在本地登陆Espace，让小伙伴再传过来。。搞定！

先看main函数如下： 1 /** 2 * @brief Main program 3 * @param None 4 * @retval None 5 */ 6 int main(void) 7 { 8 /* STM32F4xx HAL library initialization: 9 - Configure the Flash prefetch, instruction and Data caches 10 - Configure the Systick to generate an interrupt each 1 msec 11 - Set NVIC Group Priority to 4 12 - Global MSP (MCU Support Package) initialization 13 */ 14 HAL_Init(); 15 16 /* Configure the system clock to 100 MHz */ 17 SystemClock_Config(); 18 19 /*##-1- Enable GPIOA Clock (to be able to program the configuration registers) */ 20 __HAL_RCC_GPIOA_CLK_ENABLE(); 21 22 /*##-2- Configure PA05 IO in output push-pull mode to drive external LED ###*/ 23 GPIO_InitStruct.Pin = GPIO_PIN_5; 24 GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP; //推挽输出 25 GPIO_InitStruct.Pull = GPIO_NOPULL ; //默认悬空 26 GPIO_InitStruct.Speed = GPIO_SPEED_FAST; //管脚响应速度配置 27 HAL_GPIO_Init(GPIOA, &GPIO_InitStruct); 28 29 /*##-3- Toggle PA05 IO in an infinite loop #################################*/ 30 unsigned int i=0; 31 while (1) 32 { 33 ((++i)%2==0)?(HAL_GPIO_WritePin(GPIOA,GPIO_PIN_5,GPIO_PIN_SET)):(HAL_GPIO_WritePin(GPIOA,GPIO_PIN_5,GPIO_PIN_RESET)); 34 //HAL_GPIO_TogglePin(GPIOA, GPIO_PIN_5); 35 //HAL_GPIO_WritePin(GPIOA,GPIO_PIN_5,1); 36 /* Insert a 100ms delay */ 37 HAL_Delay(100); 38 } 39 }
