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)

| | use of op amp circuits with the Handy Board
|
|
Does anyone know how to get a negative 5 volts from the Handy board for an op amp amplifier circuit or set equations to figure out the gain of an standard op amp as the 741 or LM339 using Vee as ground and Vcc as +5 VDC? The equations only seem to (...) (28 years ago, 26-Feb-97, to lugnet.robotics.handyboard)

| | Turning IR xmitter on and off
|
|
Hi all, I've had a few questions on this. The ir_xmit_on and ir_xmit_off routines that I use are in hb_ir.c. You could easilly write them yourself - ir_xmit_on just does poke(0x1000, 0x40) and ir_xmit_off does poke(0x1000, 0). Note that in hb_ir.c (...)
