'onewire-testboard' smoke test
Verifies that a 1-wire bus with two devices can be searched and that a DS18b20 temperature sensor as well as a ds2431 eeprom can be accessed. Typically used with the periph-tester board.
Example output running on a C.H.I.P.:
chip4 ~> sudo ./periph-smoketest -v onewire-testboard -i2cbus 1

Overview ¶
Package onewiresmoketest is leveraged by periph-smoketest to verify that a 1-wire bus search returns two devices, that a ds18b20 temperature sensor can be read, and that a ds2431 eeprom can be written and read.
This assumes the presence of the periph-tester board, which includes these two devices. See https://github.com/tve/periph-tester
