[STM32U3] 【STM32U385RG 测评】——1.开箱点灯

很高兴收到了意法半导体和21IC论坛给予的NUCLEO-STM32U385RG开发板，今天就到公司了，拿到板子，来个开箱评测。1.拆开快递，就是这个盒子

近距离观察

根据手册上的二维码，进入ST官网

先下载原理图

找到LED引脚PA5

首先要点亮LED，就打开工程，这里我选择GPIO_IOToggle

核心代码如下：
int main(void)
{

/* USER CODE BEGIN 1 */
/* STM32WBAxx HAL library initialization:
- Systick timer is configured by default as source of time base, but user
can eventually implement his proper time base source (a general purpose
timer for example or other time source), keeping in mind that Time base
duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and
handled in milliseconds basis.
- Set NVIC Group Priority to 4
- Low Level Initialization
*/
/* USER CODE END 1 */

/* MCU Configuration--------------------------------------------------------*/

/* Reset of all peripherals, Initializes the Flash interface and the Systick. */
HAL_Init();

/* USER CODE BEGIN Init */

/* USER CODE END Init */

/* Configure the system clock */
SystemClock_Config();

/* USER CODE BEGIN SysInit */

/* USER CODE END SysInit */

/* Initialize all configured peripherals */
MX_ICACHE_Init();
/* USER CODE BEGIN 2 */

/* -1- Enable GPIO Clock (to be able to program the configuration registers) */
LED2_GPIO_CLK_ENABLE();

/* -2- Configure IO in output push-pull mode to drive external LEDs */
GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;
GPIO_InitStruct.Pull = GPIO_NOPULL;
GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH;

GPIO_InitStruct.Pin = LED2_PIN;
HAL_GPIO_Init(LED2_GPIO_PORT, &GPIO_InitStruct);

/* USER CODE END 2 */

/* Infinite loop */
/* USER CODE BEGIN WHILE */
while (1)
{
/* USER CODE END WHILE */

/* USER CODE BEGIN 3 */
HAL_GPIO_TogglePin(LED2_GPIO_PORT, LED2_PIN);
/* Insert delay 100 ms */
HAL_Delay(100);

}
/* USER CODE END 3 */
}

LED每隔100ms闪烁一下
