ESP-IDF Timer Interrupt Example We will build and create a project in VS Code with ESP-IDF extension whereby a timer interrupt will be used to toggle the onboard LED of ESP32. The LED will be set up as a digital output and will be toggled after a set number of intervals. Lets show ...

配置完成后,调用esp_err_t gpio_install_isr_service(int intr_alloc_flags)函数设置 GPIO ISR(中断服务程序,interrupt service routine) 处理服务。 调用esp_err_t gpio_isr_handler_add(gpio_num_t gpio_num, gpio_isr_t isr_handler, void *args);为相应的GPIO引脚添加ISR handler。
Push button w/ interrupt. These examples are described in detailbelow. This repository contains companion code to a talk I gave about Microcontrollers. Thetalk, and these examples, are based around the SparkFunESP-32 Thing, but any ESP32 dev board should work, with some changing of pins. ...
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 ...
打开file-example-mpu6050-mpu6050_DMP6,有现成的实例代码。由于我的esp32的板载LED灯的pin number是2,修改#define LED_PIN 13为2。中断pin 2修改为#define INTERRUPT_PIN 13 //修改后 #define INTERRUPT_PIN 13 // use pin 2 on Arduino Uno & most boards #define LED_PIN 2 // (Arduino is 13, ...
