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...
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, ...
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 attachInterrupt(interrupt, function, mode)...

Arduino-ESP32 LEDC API - ledcSetup() 该函数用于启动 LEDC ,指定通道、频率、分辨率。 uint32_tledcSetup(uint8_tchannel,uint32_tfreq,uint8_tresolution_bits); channel 选择 LEDC 通道。 freq 选择 pwm 的频率。 resolution_bits 选择 LEDC 通道的分辨率。
For example, a home automation system where the ESP32 needs to connect to the home WiFi network to access the internet, but also needs to create its own network for other smart devices (stations) to connect to it. Set The ESP32 in AP-STA (WiFi Station + Access Point) Mode ...
Bluetooth® LE, debugging via native USB in the Arduino IDE as well as low power.The Nano ESP32 is compatible with the Arduino IoT Cloud, and has support for MicroPython. It is an ideal board for getting started with IoT development.Target areas:Maker, Debugging, IoT, MicroPython ...

ESP32 支持 Deep-sleep 低功耗模式,通过配置 RTC 外设和 ULP 协处理器的工作模式,可以满足多种应用场景下的低功耗需求。 在Deep-sleep 模式时,所有由 APB_CLK 驱动的外设、CPU 和 RAM 将掉电,RTC_CLK 继续工作; RTC 控制器、RTC 外设、ULP 协处理器、RTC 快速内存和 RTC 慢速内存可以不掉电,具体取决于应...
