In this tutorial, you’ll learn how to use ESP32 interrupt pins in Arduino Core. We’ll also discuss how to use interrupts and write your interrupt service routine (ISR) for ESP32 external interrupt GPIO pins. Then, we’ll move to the Arduino Core libraries that implement drivers for the...

gpio_int_type_t intr_type; /*!< GPIO interrupt type 中断类型 上升沿/下降沿等 */ } gpio_config_t; 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 2. 将gpio_config_t 赋值后,使用 gpio_config(&io_conf);完成配置,执行完此函数后这个引脚就算配置完成了。
一、GPIO 中断使用简析 1、中断触发方式 ESP32 Arduino 有以下四种触发方式: LOW 低电平触发 CHANGE 电平变化 RISING 上升沿触发 FALLING 下降沿触发 HIGH 高电平触发 2、配置中断 在定义中断函数后,需要在 setup 函数配置中断函数 // interrupt=中断通道编号,function=中断函数,mode=中断触发模式 ...
