# I2C bus scanner
## What it does
This example scans the i2c bus in a loop and prints out a table with the addresses of the found i2c devices.
## Wiring
Connect `SCL` and `SDA` pins to the following pins with appropriate pull-up
resistors.
| Name | Description | Defaults |
|------|-------------|----------|
| `CONFIG_EXAMPLE_I2C_MASTER_SCL` | GPIO number for `SCL` | "5" for `esp8266`, "6" for `esp32c3`, "19" for `esp32`, `esp32s2`, and `esp32s3` |
| `CONFIG_EXAMPLE_I2C_MASTER_SDA` | GPIO number for `SDA` | "4" for `esp8266`, "5" for `esp32c3`, "18" for `esp32`, `esp32s2`, and `esp32s3` |
## Example output
Three devices found on a bus: 0x38, 0x60 and 0x77
