stm32cubemx配置sem32f030k6实现按键输入的单击双击和长按功能及程序

首先，您需要在STM32CubeMX中配置GPIO口作为输入模式，以便检测按键状态。然后，您需要编写代码来检测按键状态并实现单击、双击和长按功能。 以下是一个简单的示例程序，其中PA0和PA1被配置为输入模式，PA0用于单击和双击功能，PA1用于长按功能。 ```c #include "stm32f0xx.h" #define DEBOUNCE_TIME 50 // debounce time in milliseconds #define LONG_PRESS_TIME 1000 // long press time in milliseconds #define DOUBLE_PRESS_TIME 300 // double press time in milliseconds volatile uint32_t button_state = 0; volatile uint32_t button_ticks = 0; volatile uint32_t button_press_ticks = 0; volatile uint32_t button_release_ticks = 0; void EXTI0_1_IRQHandler(void) { if (EXTI->PR & EXTI_PR_PR0) { EXTI->PR |= EXTI_PR_PR0; // clear interrupt flag if (GPIOA->IDR & GPIO_IDR_0) { // button released button_ticks = HAL_GetTick() - button_press_ticks; if (button_ticks >= LONG_PRESS_TIME) { // long press detected button_state = 2; } else if (button_ticks >= DOUBLE_PRESS_TIME) { // double press detected button_state = 1; } else { // single press detected button_state = 3; } button_release_ticks = HAL_GetTick(); } else { // button pressed button_press_ticks = HAL_GetTick(); } } } int main(void) { // configure PA0 and PA1 as inputs with pull-up resistors GPIO_InitTypeDef GPIO_InitStruct; GPIO_InitStruct.Pin = GPIO_PIN_0 | GPIO_PIN_1; GPIO_InitStruct.Mode = GPIO_MODE_INPUT; GPIO_InitStruct.Pull = GPIO_PULLUP; GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH; HAL_GPIO_Init(GPIOA, &GPIO_InitStruct); // enable EXTI0 and EXTI1 interrupts EXTI->IMR |= EXTI_IMR_MR0 | EXTI_IMR_MR1; EXTI->RTSR |= EXTI_RTSR_TR0 | EXTI_RTSR_TR1; NVIC_EnableIRQ(EXTI0_1_IRQn); while (1) { // check for long press if (button_state == 2) { // long press action here button_state = 0; // reset button state } // check for double press if (button_state == 1 && (HAL_GetTick() - button_release_ticks) >= DOUBLE_PRESS_TIME) { // single press action here button_state = 0; // reset button state } // check for single press if (button_state == 3 && (HAL_GetTick() - button_release_ticks) >= DEBOUNCE_TIME) { // double press action here button_state = 0; // reset button state } } } ``` 在此示例程序中，按键被认为是单击、双击或长按的状态。中断处理程序检测按键状态并将其保存在`button_state`变量中。主循环检测`button_state`变量以执行相应的操作。请注意，此示例程序仅演示了如何检测按键状态，您可能需要根据自己的要求进行修改。
