# 06_i2c-scanner
|
|
|
|
|
|
|
|
Simple I2C device scanner.
|
|
|
|
For this example I used this [SSD1306 OLED display](https://www.digikey.com/en/products/detail/winstar-display/WEA012864DWPP3N00003/20533255).
|
|
|
|
To build the example run the following commands.
|
|
|
|
```bash
|
|
source ~/path/to/esp-idf/export.sh
|
|
|
|
mkdir build
|
|
cd build
|
|
cmake ..
|
|
make -j $(nproc)
|
|
|
|
# Flash to ESP32
|
|
make flash
|
|
|
|
# Open Serial Monitor, press CTRL+] to exit.
|
|
make monitor
|
|
```
|
|
|
|
Expected output in serial monitor at 115200 baud
|
|
|
|
```bash
|
|
Scanning I2C devices...
