Let's hope he will not pick a PIC. :) Ciao Jack

I used to think that, but experience over several projects where the choice was made elsewhere convinced me they can be very usefull. There are probably hundreds of variants, later spinoffs are very fast and there are some very good tools around. They are cheap and fast enough to use as logic replacement, rather than gate arrays, where no two manufacturers products and tools look the same or are compatable. If you want to see a really stripped down micro, have a look at the Fairchild ace series. It's just about choosing the right micro to fit the task at hand... Chris

It's just that many people /don't/ choose the best device for the job - they pick an 8051 or PIC because that's the microcontroller they've heard of, or because they used one ten years ago. Sometimes an 8051 or a PIC /is/ the right device to pick, but when someone posts with no more than vague ideas about some tools, the chances are they are at an early stage in the process. Now is the right time for the OP to think about what they really need, and what device family is best suited to the job - before investing time, effort and money in tools, hardware or development. |
