Hi, Is there any way to disable the LCD display? Rather the heartbeat. I'm not using the LCD, and I don't want anything printing the the LCD, heartbeat included.

(...) Mike, Not enough info to determine your problem. Are you using the Output Compare functions, or are you trying to emulate that functionality some way? The OC lines are hardware-set, so they go off whenever the free-running counter matches some (...) (28 years ago, 27-Feb-97, to lugnet.robotics.handyboard)

Hi- I'm attempting to write an assembly routine to control a pulse width, but I can't seem to get the timing down. For example, I can output a 3.33ms pulse width, but if I run the routine again, it sometimes jumps to 3.5ms, and then jumps back down (...) (28 years ago, 27-Feb-97, to lugnet.robotics.handyboard)

(...) Good question! We had a lot of noise problems and learning curve stumbles along the way. Our first bad news was that we had a range of a few inches. We finally beat that one fooling with frequencies, caps, etc. and then found out our range was (...) (28 years ago, 27-Feb-97, to lugnet.robotics.handyboard)

How do you use the expansion header on analog inputs 0 to 3? I could not find specifics on its use in the documentations. Thanks, Nathan Marcantel nathanm@mail.utexas.edu 512-272-8024 6517 Carisbrooke Lane Austin, TX 78754 (28 years ago, 27-Feb-97, to lugnet.robotics.handyboard)

| | SPI Interrupts (Vector2X)
|

I am at it again! I am trying to get the Vector2X working on the SPI bus of the handy board. I have read the docs, and they seem to make sense, however, I cannot get the code to work. I have the Vector2X running as a master, my assumption is that (...) (28 years ago, 26-Feb-97, to lugnet.robotics.handyboard)

yes, they do. In case you didn't know, schematic diagrams for the Handy Board are available from the web site. They show this wiring, including the fact that the user knob is wired to PE7. -Fred -- This message was composed using Articulate Systems' (...)

| | handy board analog inputs

Hello, I am trying to run an assembly language program on the handy board without IC. Do the analog inputs on the handy board, marked 0-6 on the board correspond exactly to PE0-PE6 on the chip? Does the 0 input of J1 go directly to the PE0 pin? I (...) (28 years ago, 26-Feb-97, to lugnet.robotics.handyboard)

| | Adding Functions to IC
|
|
Is there a way to add functions to IC? Maybe they're already somewhere that I am not aware of. I need to add ir_xmit_on and ir_xmit_off to my functions list. I know that I can poke them but I just wondered if they were already on a functions list (...) (28 years ago, 26-Feb-97, to lugnet.robotics.handyboard)
