I have written a new trigger program which records the time of each pump to flash. The time it records is local mote time, so remember to note the time the trigger was turned on. The program makes the blue LED turn on whenever the pump is pushed down. If the mote fails to write to flash, the red LED will flash.
It is on the Ubuntu computer upstairs in ~/Desktop/newtrigger . It contains subdirectories for reading and clearing the flash. Refer to the readme in ReadFlash for information on how to read the flash.
The three modified triggers are currently programmed with this program.
