HI! My name is Mike and I just joined the list. I stumbled across it when searching for info on the HP 54645D MSO. I am seriously looking into one as my old Tektronics scope took a dive. I have been using pics for a little while now, but only in one design that was useful (a consulting job). I have plans for products using PICs that are in development now. Anyway, I'm not sure if this is the proper place for this (and if it isn't, please let me know) but does anyone have a 16J picmaster probe they would like to sell? (The one for most of the 16c5x,7x series) Is there a site better suited for finding people that might be getting rid of one? Has anyone (I'm sure there is) that has used a pic for datalogging? More particularly, used an EEPROM / FLASH /SRAM to store data? I need to store about 25-30 samples per second for at least 20 seconds. Any suggestions? It doesn't necessarily have to be non volatile especially if the write rates are too slow for NV, but it would be a nice touch. I want to store data for later retrieval by a PC. Thanks for the bandwidth! ----------------------------------------- Mike Montalvo G-FORCE Motorsports http://www.g-forcemotorsports.com 516-794-0858
