I am in the startup making a datalogger. I'll use a ADS8320, 16 bits serial a/d and a pic (16c84). I wonder if it is possible to use a RAM from a pc or at least a larger ram that can keep the data until it is downloaded to a pc. thanks for any help Ernst -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
