I think I understand Dave. I'm currently using a 6 v battery pack to power the Pololu ( this was just for determining my ports) but in my final connections I need a source at 5 v either with a voltage regulator stepped down from 12v or battery source.

Yep, that's right. I don't know if the 6vdc supply was causing problems with the Pololu that needs 5vdc but somehow you have managed to get it to work. Good work!

Oh the drama. When I re-activated my EZ and connected, none of my H-Bridges worked. eek

All port settings are the same, I get a clean connection to the board, read power going in via my test meter but yet no responses.

Now I understand you're only allowed 1 H-bridge per project so I created multiple projects, each with their own H-bridge, however I used the same EZ. Perhaps the problem is I can only use a single bridge per EZ itself. Not a big issue because I have several.

Anyone care to chime in?

Thanks,

Daniel

@mulberry.

Just to correct you, you can in fact use 2 H-Bridge's on a single project. It's only one Movement Panel your allowed to have. This would mean that a Movement Panel would control one H-Bridge, while you would have to script the other one. Or you could script both and use a custom movement panel. Using two h-Bridges is not done to often as it uses up more ports, and to set up two H-Bridges in ARC is a little bit more complex than adding the H-Bridge movement panel, but it can be done with a little extra work.

Yes, Steve's correct. You can have as many H-Bridges or motor controllers as you want on any one project. You just need to write scripts to control them all. You don't even have to have a Movement Panel installed.

Don't know why your h-bridges are not responding. When strange things like this happen to me I shut down the robot and EZB, reboot the computer and restart ARC, the robot and EZB. Also check to see the H-Bridges are getting power and the connections are tight.

Writing script may be the next evolution but I think for now I'll use my many EZ's.

BTW Dave. You have 3 running you said. I'm assuming you connect to all 3 at the same time and just have multiple project windows. Have you encountered any issues?

Thanks,

Daniel

@Mulberry.

No problem. When you get around to it, scripting the H-Bridge motor controllers won't be too difficault. I mentioned that you can only use one Movement Panel per project to control one motor controller, but with scripts you can use a custom Movement Panel to control two H-Bridge motor controllers (which of course would depend on how you wish to use them in a project).

A few months back now, I asked about using multiple motor controllers in one project and got some great advice. Have a look here as you may find it useful.

Hi Daniel, I have many motor controllers operating in my B9 and only one project controlling the entire robot and all the controllers. I now have two EZB's controlling every sensor, light and control board through that one project. There's no reason why you need to be running several projects to control your B9 unless you want more then one movement panel. BTW, I have no movement panels at all installed in my project.
