[hpsdr] HPSDR Front Panel

Mon Jul 19 19:10:34 PDT 2010

If I were planning to mass produce a controller I'd go with that kind
of PIC based design because I'd want to reduce my recrring costs.  But
if I were building just one controller I'd invest and extra $200 in a
higher powered processor so I could greatly reduce my engineering
time.

With the higher priced CPU you can run Linux or Unix and then have use
"standard" development tools and these is no shortage of MIDI software
that you could use.  Also the end product could have features like a
self hosts web site for configuration (almost all small routers have
this.)   I'd move up from the Pic to something at least like the Arm
that is found is many routers and many moble devices.
