A colleague of mine gave me a device that is able to send data via i2c. He has already been able to recieve this data on the Arduino via the following library/Function https://www.arduino.cc/en/Reference/WireRequestFrom
However if i try to read out the bus on the raspberry pi (raspbian), I'm only able to recieve the first 5 values when using "i2cdump" or "i2cget". Afterwards there is a delay about 1 second when executing "i2cget" and I recieve a "Error: Read failed".
Does anybody has experience with i2c Read Errors or have a clue about what the cause could be?
About the Setup: Raspbian Jessy, I2C switched on via the raspi-config menu. No further Changes.
