I recently got my hands on a DeltaTRAK temperature logger. This type of device is normally used to ensure the temperature of sensitive materials stays within a certain range during transport. As I understand it, they are designed to be used once and then reset by the company.
I used it to track the temperature of my luggage during a flight and now I'd like to play around with resetting it. I dont know much about microcontrollers but I'd like to use this as an opportunity to learn.
I cracked it open, one screw.
The most interesting part seems to be the six points along the top labelled: MCR, PVD, GND, PGD, PGC, and PGM. My research points to MCR referring to a reset of some kind. PVD
may be some programming voltage. GND needs no introduction. PGD, PGC, and PGM seem to be part of some PIC microcontroller programming system.
Heres a closer shot of the mc
Its a PIC18F14K50 8-bit microcontroller.
The other chip on the board is a FM24C64A. Not sure what it is.
I have tried shorting MCR to GND, it didnt seem to do anything. Do I need to buy some programmer to play with this?
