Hello All, I am attempting to display characters on the Handy Board screen, using pure assembly. I know the routine needs to be copied to internal RAM, put in single chip mode, then activate the display - as stated by the hardware reference manual. (...)

This must seem really elementary to everyone, but inside of my program, how do i reset the value of the ir_data? I've been trying everything in the handyboard technical references but it gives me either a syntax error or Cannot assign type <pointer (...) (27 years ago, 24-Mar-98, to lugnet.robotics.handyboard)

(...) Handy Boarders: I cannot resist putting in a couple of plugs here for two good related resources: 1) The 68HC11 Microcontroller by Joseph Greenfield. This comprehensive book has a very nice section on reading/writing to I/O ports using timer (...) (27 years ago, 23-Mar-98, to lugnet.robotics.handyboard)

After sutdying the schmatics for an hour, I got up to get something to drink. When I came back I noticed that digital 1 is connected directly to the IC 1 input line and digital 2 goes to IC2 via a pullup resistor. It seems that the answer was right (...)

(...) <snip> Sure. Use an oscilloscope. It seems to me that if you're looking to hook up the receiver to the HB, couldn't you instead just run the receiver output through a capacitor to smooth it out (and maybe a resistor to scale the voltage) and (...)

yeah, I know what you mean... I have a TI-83 graphing calculator (www.ti.com) and have been thinking the same thing. Check up in your reference manual to see if it has anything on its protocols.

Hi all. Is there a way for me to read the pulsewidth comming out of a RC receiver? What I'm trying to do is to have an onboard Futaba R/C receiver just in case my bot gets into trouble that it can't get out of on it's own. I want to use my HB (...)

I've just been looking into BEAM robotics recently and it is very, very interesting indeed. Mark Tilden's claims may be hard to believe and it seems counter-intuitive, but I think he has his head screwed on right and I definitely reckon that the (...)
