 | | sonar test and others
|
| Hi, My sonar is working!, I checked the wires and noticed that when soldered J12, I forget to cut the tail of the wire, maybe this was making contact with other part of the HB, I have also noticed the limitation to measure more than 2.6 m. , has (...)

| | | | | memory problems!!
|
| Hi, I'm writting a C program for the HB that will allow it to be controlled by a LabVIEW software interface. The problem i'm having is that when my C code goes above 8Kb in size IC won'teven compiule it, it just crashes and the dos window closes. (...)

| | | | | From Mac to Linux
|
| Hi, Guys: I meet a strang problem. We developed robot under Mac using IC version 3.1, everything works. Now we move to linux, we let fd(2), but it goes backward, we let bk(3), it goes forward. fd(3) and fd(3) is good. Sonar works. But our four (...)

| * Giang Tran <gt4025@chi.devry.edu> [000420 21:49]: (...) Silly me, I wasn't thinking that there would still be a mid point to the resistance. I was stuck on the fact that the new resistors would trick it into thinking that it never reached it's set (...) (24 years ago, 21-Apr-00, to lugnet.robotics.handyboard)

| | | | | New Servo Routines?
|
| Because I have an expansion board, I cannot use my hacked up servo motors together with unaltered motors. In order to stop the hacked servos, I have to call init_expbd_servos(0) which dis-allows use of the other ones. Does anyone have any asm code (...)

| | | | | sound generating questions
|
| hi, we have to generate a square wave for a pizeo buzzer, we would use the one on the handyboard, but this one has to be encased in a shell, which would only be unable to fit the handyboard. we tried just switching a digital out, on and off, and the (...)

|
| Dear All Does anybody have a routine to measure the width of PWM pulses from an R/C receiver (ie the pulses which control the servos). TIA David Young (24 years ago, 18-Apr-00, to lugnet.robotics.handyboard)

Thank you to everyone who sent me a link to a picture of a completed sonar assembly, they've been very helpful even though I still can't get it to work :( As such, I still have questions, but for now this is the only one: - Does it (...)
