I will soon be getting Rev 1 of my design up and running with a XC167 uP. I'm looking for opinions from people with experience getting uP boards up and running in regards to Logic analyzers and scopes. I need to buy a new scope anyway and am looking at the Agilent MSO 4ch + 16logic scope. It has I^2C and SPI triggering which I like, but would I be better off buying a real Logic analyzer? Is it even necessary? My interest is just to help speed up getting this up and running. I'm assuming I will run into problems talking to deferent devices along the way. I know its hard to believe, but I actually have made mistakes before.........LOL....... Just looking for people opinions. Thanks, Mike Also, Anyone know of any good computer based logic analyzers with good and user friendly software?
