I2C Scanner is a simple sketch that scans the I2C-Bus for devices. You can upload the code to your Arduino to find out the I2C address of the modules. Upload the below sketch and open the Serial Monitor to view results: #include <Wire.h>void setup(){ Wire.begin(); Serial.begin(9600...
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; Se...

接下来使用函数“LiquidCrystal_I2C lcd() 设置地址、列数和行数。地址为 0x27(使用 I2C Scanner Code 发现)。列数为 16,行数为 2。之后,我们可以使用“lcd”调用显示器。您也可以将多个 I2C LCD 与 Arduino Uno 一起使用。但为每个显示器设置不同的地址和变量。 LiquidCrystal_I2C lcd(0x27, 16, 2); ...

It has been made sure that MPU9250 is a proper functioning I2C slave device with address 0x68 when AD0 is connected to the GND level by means of running an i2c scanner code on an Arduino UNO (it detects a device on 0x68). According to your suggestion, I added 12.5KOhm pull-up resi...
