Servotor32 connecting but not communicating

Hexy Questions, Problems and Suggestions
#1

I’m using Servotor32_2v0 and PoMoCo 1.0 and the Servotor32 driver v1.1 on a Windows 7 64bit machine.
When the USB cable is plugged in it shows up in Device Manager as Com3. When I open up PoMoCo
it shows as connected to Com3. When I click on a button on the left side of PoMoCo, ##### on Com2 shows up for every servo command.
If I change the Com port to Com2 it still does not cause the servos to move when giving commands.
Any thoughts as to why PoMoCo says that it’s connected to Com3 and then sends the commands out on Com2? Neither one is occupied
according to Windows.

Thanks,
Bruce

Hi Bruce,

Are the servos moving otherwise? Like say, are they centering on pins 0,1,2 or 3? This would verify the board is getting power and functioning properly.

Were you able to communicate with it via the Arduino software? Were you able to get any serial commands working?
arcbotics.com/products/servotor32/commands/

This would verify that the controller is functional and responding to serial input.

They are centering now and when I originally built the legs.
ArcBotics PoMoCo shows this:
Attempting to connect to Servotor
Connect Successful! Connected on port: COM3
initilizing servos
servos initalizied
sent ‘#0L’ to COM2
sent ‘#1L’ to COM2
ect…

Any suggestions on what needs to be done to get this to communicate correctly?

Hello…
Do I have a defective board or what? From the looks it my Hexy will not run until this gets resolved.

I had the same problem and, after some frustrating troubleshooting and research, I finally resolved it by re-designating the COM port Windows automatically assigned from COM10 to COM2, so it would be getting the commands from PoMoCo via the correct port. I found instructions on how to change the COM port at plugable.com/2011/07/04/how-to-c … -windows-7, but it basically boils down to launching device manager (with administrator privileges), selecting Ports, choosing the Leonardo, going into Port Settings, choosing Advanced settings, and changing the port to COM2 from the drop-down menu. After that, I’ve been able to use PoMoCo without a hitch. Hopefully you’ve already found a solution, but if not, I hope this helps you and/or anyone in the future who might have the same problem.
