pololu / dual-vnh5019-motor-shield Goto Github PK

I'm using this motor controller to power a basic tank robot, and I'm now trying to add a servo to it to give it some more functionality. When I added the Servo to my code the Motor Controller refused to work correctly, not outputting any current or changing the colors of the indicator LEDs. I traced the issue to the servo.attack(pin); command. I attached the servo to pins that were listed as unused on the pololu site and this issue still occurred. Is there a fix for this? Thanks.

Recently ran into an issue where Using a servo on a Mega 2560 with two dual-vnh5019-motor-shields to drive 4 motors causes one motor to fail.

All 4 motors work fine until servo.write is in the loop then one of the motors will not turn on.

Seems something in the dual-vnh5019-motor-shield library and the servo.h library conflict

Hello,

I've purchased a VNH5019 motor driver shield and 2 pololu motors (37Dx68L). When trying to read currents at a higher frequency (e.g. replacing the lines (i%200 == 100) for (i%2 == 1)), I get this (where horizontal axis is the index of each measure, and vertical axis is current in mA).

Since the desired speed is an increasing and then decreasing ramp, I would have expected smoother results. I guess I could just use a low-pass filter to reduce noise, but I would like to know if this is a problem in the library that could be solved easily. Thanks in advance!

Every time I try to run the demo I'm getting the same "M1 Fault", and its getting quite annoying. I'm using an Elegoo Uno R3 (same thing as Arduino Uno R3) at the moment and using a jumper to power the shield and the Arduino through USB. I'm not sure exactly what is causing this. If it is my soldering there may be a problem, but I don't think that's what it is. Any help would be greatly appreciated!

New to programing, tried running on Arduino Uno, removed it repeatedly with no access. Followed instructions and still get this message:

I have 4 12VDC motors connected to two dual VNH5019 motor drivers. but one M1A and M1B isnt powering the motor. If its not plugged in then the Led indicators lightly glow and nothing glows at all if I plug it into the motor. I tried the motors with other connection and it works fine. Could it be a connection issue?

Hello Kevin,

I purchased two Pololu Motors plus driver shield months ago and have had nothing but problems with this code you offer here. It does not work. The Arduino IDE cannot compile it the way it is compiled. I have looked for help to correct this issue for months to no avail.

There is something either corrupt in a single file or the naming conventions with the - () that were put in file names, but even if renamed, Arduino IDE cannot recognize nor upload this or any other Pololu VNH 5019 Motor driver/shield coding. The IDE will either give 'fatal error'..."no such file in directory"
or this one:

"
I have tried everything from uninstalling/re-installing, naming convention correction you name it and the library cannot locate nor process these files.
Could you please look into this at your earliest convenience, test and post a proper code that actually works? I have been finished my project build for several weeks and have been totally held up by this infuriating issue.

Greatly appreciated.

void setM2Brake(int brake) is not in .h file. I am missing something to be able to use the Set??Brake command?
