|
| If I add a separate motor power to the L293's, can I keep the ground lines common? If not, what pins are motor ground? (I know pins 4,5,12, and 13 are ground) Thanks. -John (...) (30 years ago, 23-Mar-96, to lugnet.robotics.handyboard)
| | | | | Re: Resets
|
| The MB design keeps ground in common, but the ground to the cpu, has an inductor in line with it, the HB also has a inductor on the ground side, I think. You might want to put an inductor on both sides of the motor, with a cap inbetween both of (...) (30 years ago, 24-Mar-96, to lugnet.robotics.handyboard)
| | | | | DC Motor Position control
|
| I am wondering if anyone tried to write an IC program for DC motor position control using PID/P or whatever with a handyboard. I am also looking for a good precision DC motor (with encoder and gearbox integrated), I very appreciate your help for any (...) (30 years ago, 24-Mar-96, to lugnet.robotics.handyboard)
| | | | | Re: OC2 and OC3 outputs?
|
| Take a look at the schematics, which are linked from the top page of the Handy Board web site. The info you are looking for is in the CPU / memory schematic. For the DC Motor outputs, the board uses a separate output latch---not the timer outputs. (...) (30 years ago, 24-Mar-96, to lugnet.robotics.handyboard)
| | | | | TOC 2 & 3
|
| AAAARRRGGGHHHHHH!! After the pain of relearning assembler and getting interrupt routines to work, it seems my assumption of the availability of TOC 2 & 3 is incorrect. I need 2 (wanted 4) pulse trains to go out. According to the diagrams Fred (...) (30 years ago, 24-Mar-96, to lugnet.robotics.handyboard)
| | | | | pulse trains
|
| Mike, Out of curiosity, what are you using the pulse trains for? (If you're running multiple servos, I think I know a single-chip hardware mod to drive up to 8 servos from a single timer output.) -- Randy (30 years ago, 24-Mar-96, to lugnet.robotics.handyboard)
| | | | | Re: Driving large motors with the Handyboard
|
| (...) Thanks for the tip. I got a hold of the book and read some of it. :) I was wondering if sending pulses to the motor would cause "choppy" rotation....or does it occur so fast that inertia effects make it "smooth". Also, with an h-bridge, is it (...) (30 years ago, 25-Mar-96, to lugnet.robotics.handyboard)
