Program Modifications
The
EepromDataStorageWithReset.bs2. It has been modified so that you can start, stop and
restart datalogging with your board's Reset button. You can disconnect the board from
your computer to perform the datalogging, and reconnect it to display the measurements
in the Debug Terminal. This is a crucial feature for taking field measurements and then
displaying them later.
DatalogAcceleration.bs2 has a modified Initialization section that makes the piezospeaker
beep every second for ten seconds before it starts datalogging.
