 | | Smooth PWM with IC 3.2
|
|
I know this is an old thread but I am just now getting to the point where I can finally start programming. I am using IC 3.2 and the expansion board. I downloaded the smooth PWM routines from Newton Labs but I get errors when I load them into the (...) (26 years ago, 29-Apr-98, to lugnet.robotics.handyboard)

| | More Polaroid problems!
|
|
Well, everything seemed ok, but now (we are in a crunch again, the final presentation is Friday!) there is another problem. We seem to be getting some erroneous distances and I think I know why. The echo signal is pretty noisy, so my question is, (...) (26 years ago, 29-Apr-98, to lugnet.robotics.handyboard)

(...) There is a little strip of four pins for external battery power and are available with the standard battery pack installed. Two of these are battery positive, two are at ground. Shorting them out is a good way to let the smoke genie loose. (26 years ago, 28-Apr-98, to lugnet.robotics.handyboard)

I am trying to get two handyboards to exchange data via the IR. I have tried code from the Dave Negro and Pete McCann code, but I still cannot get reliable data transmission at any range. Summary of situation: REC80-IR.icb: Reliable reception of (...) (26 years ago, 28-Apr-98, to lugnet.robotics.handyboard)

Note that sonar in air is susceptible to the same environmental issues as sonar anywhere. In particular it is susceptible to changes in temperature and changes in air pressure. Both of which create a boundary layer that reflects some of the energy. (...) (26 years ago, 28-Apr-98, to lugnet.robotics.handyboard)

| | Trouble with Tom Brusehaver's Vector 2X routines
|
|
Hi! Is there anybody else having trouble running his V2X with Tom Brusehaver's routines? With my own very crude IC-routines I get it working, but I'd like to use Tom's, because they are much more comfortable. Any help appreciated! Alf (26 years ago, 27-Apr-98, to lugnet.robotics.handyboard)

(...) Thanks for this excellent article on driving stepper motors from the Handboard. One little yet very important question: when you say "the common wires need to be connected to the motor positive supply" what exact handyboard pinout are you (...)
