 | | More Motor Speeds
|
| I want to increase the resolution of the motor driver routines provided by Interactive C, so that there are more than 7 speeds. Using the method of generating PWM signals in the Mobile Robots Book, this seems easy. However looking at the primitive (...) (28 years ago, 23-Feb-97, to lugnet.robotics.handyboard)

| it's harder than you might expect, b/c the PWM routine is 'hard-wired" into the pcode file. basically, you have to make the changes in pcode.asm, and reassemble the pcode_hb.s19 file. -fred In your message you said: (...) (28 years ago, 23-Feb-97, to lugnet.robotics.handyboard)

| (...) ???? 7 speeds??? We use the IC that comes with the Gleason Associates Handyboard where motor(0,100) runs motor 0 full speed ahead motor(1,-33) runs motor 1 backwards at 1/3 speed where speeds vary from 1 to 100 in either direction. Can't you (...) (28 years ago, 23-Feb-97, to lugnet.robotics.handyboard)

| (...) You will have to rewrite the code in the interrupt functions. It isn't "hard" but it does require that you understand what IC is using the various timers for. The best documentation for that is the PCode itself. I don't believe you can use the (...) (28 years ago, 23-Feb-97, to lugnet.robotics.handyboard)

| (...) Either I'm confused or we're talking two different animals. Our pcode_hb.s19 that came with the Gleason Handyboard, allows variable motor speeds from motor(0,-100) to motor(0,100) with great and fine control. In our first test we converted (...)
