Hello, i an trying to add additional Hardware to the i2c bus. While it works fine without the NAVIO2 (Pi only) i can not get an answer from my sonar via the NAVIO i2c port.
i2cdetect works and finds the correct address
i2cget results in an error
i also tried using the i2cdev functions but i also receive a “Failed to write reg: Input/output error”
i try to connect a SRF02 which returns a revision number upon read from the register 0x00
anybody got an idea why i get the error?
