In this tutorial, we will learn to use the MPU-6050 MEMS module with ESP32 and ESP8266 to measure accelerometer, gyroscope, and temperature values using MicroPython firmware. Firstly, we will see an introduction of MPU6050 such as pinout diagram, pin configuration. Secondly, we will see how t...
out -> SetPinout(27,33,32); //设置接到MAX98357A的引脚, GPIO27(串行时钟SCK)-->SCLK, GPIO33(字选择WS)-->LRC, GPIO32(串行数据SD)-->DIN aac->begin(in, out); } void loop(){ if (aac->isRunning()) { aac->loop(); } else { aac -> stop(); Serial.printf("Sound Generator\n...
一、ESP32 GPIO简介 1.ESP-WROOM-32 30 PIN 开发板 PINOUT 如果您跟我一样使用的是ESP32 30针开发板,您可以使用下面的GPIO图作为参考。ESP32 30针开发板GPIO引脚图 注:有几种开发板,如36针开发板和ESP32-Pico-Kit以及其他几种。我不在这里全部列出,但你可以使用这里的引脚定义作为参考。 2.ESP32的基本引...
UNO style boards with a Wemos R32(ESP32) label are also available at low cost with the same pinout. Unfortunately the typical UNO/mcufriend TFT display board maps LCD_RD, LCD_CS and LCD_RST signals to the ESP32 analogue pins 35, 34 and 36 which are input only. To solve this I linke...
https://randomnerdtutorials.com/esp32-pinout-reference-gpios/ 接入继电器之后,却不能控制其闭合或者断开(水位传感器也是,单独供电时,传感器信号没能正常传入ESP32) 原因分析: ESP32的GPIO引脚最高输出为3.3V电压,无法驱动继电器工作。继电器本质上依赖电压高低差而实现电磁的吸合以及断开 高电平--电压5v---断开 ...

How to install ESP32 library in Arduino IDE So now let’s perform a simple example to connect a push button with any GPIO pin and turn on an LED connected to another digital pin. As shown in the above pinout, we will be usingGPIO15to connect the push button andGPIO22to connect a pu...
I've used several versions of PCM5102 DAC boards purchased from eBay. They've all had the same pinout, no matter the form factor. There are several input configuration pins beyond the I2S interface itself that need to be wired: 3.3V from ESP8266 -> VCC, 33V, XMT ...
