通过两个按键任务分别控制不同的点灯案例
创建 4 个任务在点灯任务的基础上在创建两个按键任务 Task_led间隔 500ms 闪烁 LE1 Task_led2间隔 1000ms 闪烁 LED2 Task_key如果 Task_led存在则按下 KEY 后删除 Task_led否则创建 Task_led Task_key2如果 Task_led2正常运行则按下 KEY2 后挂起 Task_led2否则恢复 Task_led2
2、CubeMX配置
2.1 GPIO初始化 2.2 任务建立 3、KEIL 5代码编写
3.1 main.h初始化 #define LED_ON HAL_GPIO_WritePin(LED_GPIO_Port,LED_Pin,GPIO_PIN_SET)
#define LED_OFF HAL_GPIO_WritePin(LED_GPIO_Port,LED_Pin,GPIO_PIN_RESET)
#define LED2_ON HAL_GPIO_WritePin(LED2_GPIO_Port,LED2_Pin,GPIO_PIN_RESET)
#define LED2_OFF HAL_GPIO_WritePin(LED2_GPIO_Port,LED2_Pin,GPIO_PIN_SET)
#define key HAL_GPIO_ReadPin(key_GPIO_Port,key_Pin)
#define key2 HAL_GPIO_ReadPin(key2_GPIO_Port,key2_Pin) 3.2 功能实现 任务1:
