STM32CUBE增加4个按键| 按键名 | 引脚 | | KEY_1 | PC4 | | KEY_2 | PB10 | | KEY_3 | PC13 | | WAKEUP | PA0 |
配置b_config.h 本次实验测试b_button功能，使能Thirdparty里面的FlexibleButton 添加Flexiblebutton代码 添加BabyOS\bos\core\thirdparty\FlexibleButton\目录所有文件，添加头文件路径 设置按键ID及按下时的逻辑电平
- //b_button.h内添加
- typedef enum
- {
- USER_BUTTON_1,
- USER_BUTTON_2,
- USER_BUTTON_3,
- USER_BUTTON_WAKEUP,
- USER_BUTTON_MAX
- }bBUTTON_ID_t;
-
- //b_button.c内添加按下后的逻辑电平
- static flex_button_t bButtonList[USER_BUTTON_MAX] = {
- [USER_BUTTON_1] = {
- .pressed_logic_level = 0,
- },
- [USER_BUTTON_2] = {
- .pressed_logic_level = 0,
- },
- [USER_BUTTON_3] = {
- .pressed_logic_level = 0,
- },
- [USER_BUTTON_WAKEUP] = {
- .pressed_logic_level = 0,
- },
- };
添加读取按键值和回调
- //main.c添加
- /* USER CODE BEGIN 0 */
- uint8_t bButtonRead(void *p)
- {
- uint8_t tmp = 1;
- flex_button_t *btn = (flex_button_t *)p;
- switch(btn->id)
- {
- case USER_BUTTON_1:
- tmp = HAL_GPIO_ReadPin(KEY_1_GPIO_Port, KEY_1_Pin);
- break;
- case USER_BUTTON_2:
- tmp = HAL_GPIO_ReadPin(KEY_2_GPIO_Port, KEY_2_Pin);
- break;
- case USER_BUTTON_3:
- tmp = HAL_GPIO_ReadPin(KEY_3_GPIO_Port, KEY_3_Pin);
- break;
- case USER_BUTTON_WAKEUP:
- tmp = HAL_GPIO_ReadPin(WAKEUP_GPIO_Port, WAKEUP_Pin);
- break;
- }
- return tmp;
- }
-
-
- void bButtonCallback(void *p)
- {
- flex_button_t *btn = (flex_button_t *)p;
- switch(btn->id)
- {
- case USER_BUTTON_1:
- b_log("key_1 event: [%d]\r\n", btn->event);
- break;
- case USER_BUTTON_2:
- b_log("key_2 event: [%d]\r\n", btn->event);
- break;
- case USER_BUTTON_3:
- b_log("key_3 event: [%d]\r\n", btn->event);
- break;
- case USER_BUTTON_WAKEUP:
- b_log("wakeup event: [%d]\r\n", btn->event);
- break;
- }
-
- }
- /* USER CODE END 0 */
调用bButtonInit
- /* USER CODE BEGIN WHILE */
- bInit();
- bButtonInit();
- while (1)
- {
- bExec();
- /* USER CODE END WHILE */
-
- /* USER CODE BEGIN 3 */
-
- }
- /* USER CODE END 3 */
开始测试1.按键各按一次 2.key_1长按
测试结果：
子模块采用BabyOS master分支 https://gitee.com/notrynohigh/BabyOS
