led2 闪烁视频

电子产品世界《得捷手势翻页笔活动》 STM32H503RB开发板 官方例程闪烁led2_哔哩哔哩_bilibili

串口3官方例程修改，打印图片

首先对  MX_GPIO_Init();进行io口的配置

再在while(1)循环里面添加    HAL_GPIO_TogglePin(LED2_GPIO_PORT, LED2_PIN);

进行led2的翻转

int main(void)

       - 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
