当使用最新版本Arduino IDE 2.3.4 开发esp32项目时使用ledcSetup()和ledcAttach()函数时会编译出错,控制台窗口提示‘ledcSetup‘ was not declared in this scope针对此问题解决方法。 一、报错解释 ledcSetup()和ledcAttachpin()已经在3.0 arduino.h移除了 二、解决办法使用ledcAttach:设置 LEDC 引脚的给定频率和分辨率。LEDC 通道将自动选择。 使用ledcWrite:设置 LEDC 引脚的占空比...

As you can see, there’s a warning sign besideESP32-S2. That’s not of concern as long as there is a device underPorts (COM & LPT). In this case, we have the ESP32-S2 connected to COM Port 6. Make a note of this. Step 2. Install and Setup Arduino IDE for programming ESP32...
I'm sorry if this has been asked before, the ESP8266 is a new world to me and is a bit overwhelming. My end goal is to have the ESP8266 communicate with an Arduino Nano Every and an MIT app inventor on my phone so that my phone can send commands, via wifi, to the Nano Every....

arduino-esp32 1.0.4 Arduino ide 1.8.10 Just wondering if this is an acceptable way of finding the common channel to be used by espnow. Having used espnow with an earlier arduino-esp32 release, it was sufficient to do:[ Code: Select all WiFi.mode(WIFI_STA); WiFi.disconnect(); uint...
ESP32 could be VERY hungry when initializing the Wifi. I'm using a 3.3V Arduino Mini (8MHz) with ripped-off voltage regulator and power led, which I supply by two Alkaline batteries connected to the 3.3V VCC pin directly. In deep-sleep, this should last for 57 years. This is 20...
