使用I2C扫描工具（如i2c_scanner）确认设备的I2C地址。5.I2C总线冲突 确保I2C总线上没有其他设备冲突。
Arduino/ESP8266与其他设备通信，例如OLED显示器、气压传感器等，可以使用I2C通信协议。也可以使用两外两个...
1、将一个I2C器件连接至arduino的SDA、SCL引脚(UNO R3 连接A4、A5) 2、将如下代码烧入arduino,打开串口界面即可得到I2C设备的地址。 #include <Wire.h> void setup() { Wire.begin(); Serial.begin(9600); Serial.println("nI2C Scanner"); } void loop() { byte error, address; int nDevices; Serial...
I am trying to get a MPU6050 working with ESP32. The following code works, with a minor adjustment (see comment in the code) with an Arduino UNO. I ran the I2CScanner and detected the MPU6050 with the Adress 0x68, which is the default one. The connections should be right:...
根据德州仪器的数据手册，将三个地址选择位（A0、A1和A2）放置在7位I2C地址寄存器的末尾。由于有3个...

Below you will find the simple I2C scanner code taken from the examples pull-down menu under 'Wire'. I just added a few lines of code to setup the pins and add the TwoWire functions. With v2.0.1 and later and attempting to use TwoWire(1), the response is Error 5 (timeout). This...
