'i2c-testboard' smoke test

Verifies that a DS2483 and an EEPROM can be accessed on the bus. Typically used with the periph-tester board.

Requires a gpio pin to be tied to the EEPROM's write control (active low write enable).

Example output running on an Odroid-C1:

Overview

Package i2csmoketest is leveraged by periph-smoketest to verify that an I²C EEPROM device and a DS2483 device can be accessed on an I²C bus.

This assumes the presence of the periph-tester board, which includes these two devices. See https://github.com/periph/periph-tester
