For the next rev of the openscale board I would like to see four input signals provided (and used) with the code.

1. A line which says TARE - signal the board to zero out.

2. Calibrate - a signal which says that there is a 500g or known weight on the scale.

3 Start/Stop This could be one line that when true results in readings being made and sent to the logging device. Lower the value and the readings stop. Or it could be two separate lines (start and stop).

The reason's for the tare & calibrate inputs --- can be seen from the other queries about the openscale - it can be painful to reset the tare when an experiment is being setup.

The reason for the start/stop signal is so if an experiment is being created - the scale can be triggered to operate with other events.

It is possible of course to not use openscale and simply use an HX711, an Arduino ProMini and a FTDI board...essentially the openscale device (minus the TMP102) But I'd rather see openscale made to be a more flexible and usable device.
