I'm building an logging altimeter/barometer with pyro outputs
(to deploy parachutes) for a rocket project, it will basically read
the sensors and write to some sort of persistent memory which I can
download to my computer later on to analyze. I will probably skip
the pyro part for version1.
I ordered two MPX550P Pressure sensors from Freescale, and I got a
12bit A/D from a good friend of mine, does it make sense to use the
12 bit A/D instead of the internal 10bit one?
Any pointers how to get the serial part up so I can talk to a computers
serial port in a standalone setup?
It would also be nice if I could program the Arduino from that serial
Any pointers, comments or suggestions are very welcome
