把esp32和mpu60插入面包板,用跳线连接二者,使用i2c通信协议,一共需要四根线,分别是电源正vcc,地gnd,数据sdl和时钟scl。打开arduino ide,在库中搜索mpu6050,然后安装它。第一个库,我的已经安装好了,如下图。打开file-example-mpu6050-mpu6050_raw,有现成的实例代码。由于...
3. 验证esp32c3配置arduino IDE CORE ESP32核心板是基于乐鑫ESP32-C3进行设计的一款核心板,尺寸仅有21mm*51mm,板边采用邮票孔设计,方便开发者在不同场景下的使用。核心板支持UART、GPIO、SPI、I2C、ADC、PWM等接口,可根据实际需要选择。 其中LED控制 合宙CORE ESP32核心板板载2颗LED,开发者可参考表4-1进行对应...
ESP32-0.96寸OLED作为BLE Client与ESP32-BME280 BLE Server通信 总结 简介 两个ESP32开发板,一个ESP32挂载一个BME280传感器读取温湿度值并通过BLE低功耗蓝牙GATT协议发送数据,另一个ESP32通过BLE低功耗蓝牙与ESP32-BME280建立连接并在0.96寸OLED显示出BME280的温湿度值, ESP32-BME280作为BLE Server BME280传感器...

ESP32 I2C Scanner – Arduino Code Example The code example down below does the following: We start with defining initializing the I2C peripheral. And we’ll also initialize a serial UART communication to print back the results to the PC serial terminal (Arduino Monitor). Then, we’ll start ...
The Arduino Nano ESP32 (with and without headers) is a Nano form factor board based on the ESP32-S3 (embedded in the NORA-W106-10B from u-blox®). This is the first Arduino board to be based fully on an ESP32,and features Wi-Fi®, Bluetooth® LE, debugging via native USB...

but it was necessary because my hardware is a module with an ESP32 wrover integrated into a sim800L, then the main communication pins are already in use. I tested pins 0 and 14 in a simple serial communication with an arduino to see if they will be able to work, it had no problem....
Using HardwareSerial For better reliability, replace SoftwareSerial with ESP32’s UART2: #define RXD2 16 // GPIO16 = RX2 #define TXD2 17 // GPIO17 = TX2 void setup() { Serial.begin(115200); Serial2.begin(9600, SERIAL_8N1, RXD2, TXD2); // Use UART2 ...
