Reset of Teensy configuration

Configuration commands to update or initialize a Robobot with version 8 PCB.

Stop the Teensy user

If the Raspberry is running, then stop the teensy_interface

pkill teensy_interfac

The last 'e' is missing; the process names are limited to 15 characters.

Fresh software

Upload the newly compiled software (from Raspberry or directly from a PC), e.g.

./upload
Teensy Loader, Command Line, Version 2.3
Read "build/teensy_firmware_8.ino.hex": 202752 bytes, 2.5% usage
Waiting for Teensy device...
 (hint: press the reset button)

Remember to hold the power button.

Disable the CRC check to make the console printout look better (interactive flag). This also prevents the Teensy from stopping communicating due to a lack of activity (60 seconds).
