Does anyone know why these eight speeds were chosen in lib_hb.c for the motors and what would happen if the code were re-written to allow any speed between 0 and 255? int _speed_table[]= { 0b00000000, /* speed 0 */ 0b00010001, 0b01001001, (...)

OK, I haven't looked at encoders.asm but if the following doesn't help just send more questions. (...) Sounds about right. (...) TCTL2 sets rising, falling, or both edge modes; TMSK1 arms interupts; IC event sets the TFLG1 register. (...) correct (...) (27 years ago, 14-Apr-97, to lugnet.robotics.handyboard)

Hi, Thanks for the response on finding a microcontroller. I have 1 little problem left: if I'm going to use a Motorola 68F333 or the somewhat cheaper 68HC916Y1 I need a conververter from 160-lead QFP (.65 pitch) to an "normal" pinout where I can (...)

Mark Robillard has written 2 good books on robotics. No one has mentioned these books here before, so I though I would list them.

| | Fried analog port

I was taking some measurements of sensors by reading the value on the LCD display. Suddenly poof a burst of smoke came from the analog port (0). Now the only reading I have on that port is 1, but the other ports are fine. Could I have somehow fried (...) (27 years ago, 13-Apr-97, to lugnet.robotics.handyboard)

| | HB Simple Encoder Routines

Hey everyone, My partner and I are trying to use the sencdr?.icb and fencdr?.icb routines to keep position measurements of a robotic arm. The encoders are break beam and provide a signal of 4kHz max. We used 4 J-K flip flops to reduce this frequency (...) (27 years ago, 13-Apr-97, to lugnet.robotics.handyboard)

I once saw something like this, but it was very complicated to build. There were TWO separate arrangements of your wheel descriptions, and they were hinged from a set of "hips". I believe this is because, as wheel 1 is pivotting over the front edge (...) (27 years ago, 13-Apr-97, to lugnet.robotics.handyboard)

(...) That's exactly the stuff. I saw a demo of this in class, so I can't give you specifics, but it's the sort of experiment that takes about 6 minutes to try on your own. Note, however, that there are a few different kinds of the foam: i mean the (...) (27 years ago, 12-Apr-97, to lugnet.robotics.handyboard)
