I have used the development kits for the Rabbit, the TCP/IP, and the RCM-2200, the last one being the best so far. They are mutant Z80s. THe RCM-2200 has support for TCP/IP over 10BaseT ethernet as well as rs-485 and rs-232. Good as some kind of internet or LAN interface to a network of micros communicating by rs-485. A PIC 16F877 has better basic I/O functionality (more pins, more functions: a lot of the rabbit pins are used for serial comms and the ethernet controller chip) but the RCM-2200 has a _lot_ more RAM (128K) and FLASH (256K) and has more serial ports. Dynamic C comes with the dev. kit and so far works OK but I haven't really put it through the wringer, just used telnet protocol to switch relays with it. Individual modules are small and relatively cheap (about the same as a Basic Stamp but way more powerful). You don't need an expensive box like a picstart, just the special serial cable (has a max232 in it). /\/\/\/*=Martin ----- Original Message ----- From: "Mitch Miller" To: Sent: Wednesday, February 06, 2002 10:44 AM Subject: [OT]:Rabbit Processor > Has anyone used the Rabbit processor (http://www.rabbitsemiconductor.com)? > I used Z-World's Dynamic C about 10 years ago with a Zx80 development > board, but the company I was designing for went bankrupt before system > ever went into service. > > Would like anyone's thoughts regarding this micro. vs. a high end PIC. > > -- Mitch > > -- > http://www.piclist.com hint: PICList Posts must start with ONE topic: > [PIC]:,[SX]:,[AVR]: ->uP ONLY!
