does anyone know about the mechanics of getting a power glove to interface w/ a 68HC11 EVB (the $68 evalution board). Our toy'r'us is selling the gloves for $50, and my EVB is collecting dust at the moment, so it could be a good match. Any help - i know nothing about the powergloves mechanics but here's a list of the 6811's capabilities: serial ports 8 A/D's (8 bit) COP watchdog timer Multiplication and Division in the instruction set. eight bit architecture. that's all i can remeber off the top of my head...... (oh, it also has a built in EEPROM and 16 bit timer system) thanks alot. Andrew Wheeler

The 68HC11 is probably a good chip to interface to the Power Glove. I am using the obscolescent 86705S3. It has less powere than the 68HC11, but it has several timers, which I am hoping will provide the 50 KHz for the transmitters as well as simplify the timing of the pulse reception. If I were to start all over again, I probably would go for the 68HC11.

I have recieved this via mail by somebody who is having trouble posting, and I told him I would pass it along. I have already sent him my Power Glove info. ---------- I apologised for asking for these info which probably have been posted recently, but I just found out that as a student I can get the 68HC11 EVB kit for $68! Before that, I wasn't paying much attention (though I browse thru most of them) to the discussions because I thought the 68HC11 was some expensive and hard-to-find thing, so on and so fore. Could any (and every) one please email all the materials you have on the interfacing and how to get the Powerglove to do all the neat stuff. Hopefully, with 68HC11 it can do the high-resolution stuff too! Thanks in advance. E.

By the way, the 68HC811 is the nicest model and costs $20 quantity 1 from Hamilton-Avnet. the 811 has 2K of EEPROM and 800 bytes of ram. It has a bootstrap mode that loads a program on the serial line and executes it. This means no development system other than a PC is needed! Trying right now to find the cheapest way to add ram to the thing. sdw -- Stephen D.

I hope to get a glove hooked up to the EVB sometime soon. when I do, i will post all my glue logic, schematic, etc. Andrew Wheeler
