Memory Dump - Eggtimer Rocketry Eggtimer User Manual

Memory Dump

The Memory Dump writes comma-separated-variable (CSV) data to the serial port containing
the data in every memory location. This function is primarily used by the Eggtimer Technical
Support staff to debug problems that you may encounter, but you can also use it to save all of the
flight data prior to a Master Reset if you choose.
To dump the memory, hold the Button down while the power is off or the Eggtimer is in reset
mode, and continue to hold it down as you turn on the Eggtimer or release the reset. You will
hear a long beep, acknowledging the Monitor mode, and you will see a "MON>" prompt on the
screen. If you hit the "0" (zero) key, the last flight's memory will be dumped to the serial port;
if you hit the "A" or "a" key, ALL flight memory will be dumped. Hold the Button down and
release it to start the dump.
The memory dump format is:
Page No., Page Address, Memory Address, High Byte, Low Byte, Integer Value
Page No. : Page Number (0-31)
Page Address: Address within page (0-2047)
Memory Address: Address within memory (0-65534, by two's)
High Byte: Byte value of first byte
Low Byte: Byte value of second byte
Integer value: Value of integer (two's complement if negative)
Servo Set/Reset
If you have set the deployment channel(s) to servo mode, you can test the servo position and
reset the servos to the opposite position from the Monitor mode. Note that BOTH servos will be
set or reset at the same time, and this is only valid for deployment channels that have been
previously set to servo mode (either 2 or 3) in the programming screen.
To SET the servos (simulate deployment), enter the monitor mode by holding the Button down
while turning on the Eggtimer. You will see a MON> prompt on the terminal screen. Hit the
"S" key, then you will need to hold the Button down to acknowledge the function. Whichever
servos had been set to servo mode will be put into SET position.
To RESET the servos (rotate opposite of deployment), enter the monitor mode by holding the
Button down while turning on the Eggtimer. You will see a MON> prompt on the terminal
screen. Hit the "R" key, then you will need to hold the Button down to acknowledge the
function. Whichever servos had been set to servo mode will be put into RESET position
