Sounds like the kind of thing I'd do if I were launching rockets. I was in oz for a year and a bit and did a lot of travelling. Would have been nice to visit.. but I didnt think woomera welcomed visitors ( thought it was in one of those military areas) Just a couple of thoughts. My first was that eeproms are slow to write to so if you were going to use them, you would need a PIC with a large enough memory to buffer the information as it was coming in. My second was that with the amount of data I imagine you would like to collect- ie.. as much as possible.. there isn't a pic with enough memory.. or in fact processor speed to do what you really need for the job. :( shame, but I think its the truth.. perhaps once the picDSP chips come on the shelves I have no experience using the scenix chips.. I have no idea what the real differences are between them and pics, or the range they have to offer.. but I do know; they run at much higher speeds ( dont know about ram though) .. so it might be worth looking into them as an alternative. (I need them to log large quantities of info from ADC's in the large quantities.. you mean 1000 samples a second or a million. how much do you need? > ~2seconds the rocket goes up... thousands of feet at around 60g (~580m/s/s!) hahaha. 60g.. better do dome good soldering on that circuit board ! > If I could, I would like to be able to have practical help if someone lives > locally (Sydney) bummer. I left a few months ago :( Good Luck. -- Jon Baker -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY! [EE]:,[OT]: ->Other [BUY]:,[AD]: ->Ads
