The I2C Scanner example is a very common Arduino sketch example to scan the I2C bus for available devices and get their addresses (if found). That can be useful if you don’t know the address of any I2C device or just not sure about it. Just run this example and get its addresses. ...
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. 打开 ArduinoIDE,然后转到Sketch>Include Library> Manage Libraries。 2. 在搜索框中输入“SSD1306”,然后从 Adafruit 安装 SSD1306 库。 3. 选择“install all”。如果没有跳出弹窗,则从 Adafruit 安装 SSD1306 库后,在搜索框中键入“GFX”并安装该库。 4. 安装库后,重新启动 Arduino IDE。(实测非必须)...
为此,我们需要使用“I2C 扫描仪”代码运行 Arduino。 I2C 扫描器代码 I2C Scanner 代码用于查找 I2C 设备的数量和 I2C 设备的地址。首先添加包含“Wire.h”库的头文件。然后在设置部分,通过“Wire.begin()”开始“Wire”库。然后通过“Serial.begin()”以 9600 的波特率启动串行监视器。接下来在循环部分,定义两...
Uploaded i2c_scanner sketch from examples and it found a device at address 0x76, Then I unplugged only SDA pin of theBMP280then the scanner naturally could not find any device, Right after that I plugged the SDA pin back but the scanner still could not find any device. ...

Once you have the sample sketch setup you can run it any time you need to scan the bus. Alternatively you can reference the library and scan the bus from within your project as needed. I2CScanner Source Code This entry was posted in Arduino, I2C by Omar Francisco. Bookmark the permalink...
If that describes you, then try running the following sketch. It will scan I2C possible addresses and report the address of the device that responds. address of the device that responds. I2C Scanner By Nick Gammon Copy, Paste, Upload and Run!
