Basic I2C address scanner for Espressif ESP-IDF

Usage

  1. Configure the definitions at the beginning of the esp_i2c_scanner.c.
  2. Build.
  3. Flash.
  4. At boot only the code scans for devices, prints the results and exits. Reboot to perform a new scan.

Notes

  • Supports only standard (7 bit) I2C address range. It may be easily extended to the 10-bit addressing, if needed.
  • Tested on ESP32.
