Controlling more than 3 servos with labview and arduino uno

Projects Programming

Hi everyone

I am trying to control my robotic arm drive by 5 servos (3 MG995 + 2 SG90). I use Linx package with Labview to control the arm with an arduino UNO.

What ever I do I am only able to control 3 servos at the time. The wiring is correct because if I change the channel in my Labview, I am able to control all the other servos. I am sure it's a software issue. Is some one have an idea how can I control my 5 servo using the Linx software with my arduino UNO card?

The problem can be solved by replacing the arduino UNO by arduino Mega 2560.

Do you think it might help if you posted your program ?

An Uno can control 12 servos so the problem must be with your program.

Here is my program,

but i don't think that is a program failure.

The first three (left) servo work ,, the other did not :o

I have not looked at your picture because you should not post a picture of a program. Post your program as a .ino file, or, if it less than 9k long just include it in your Reply. See How to use the Forum

Don't worry Robin. It is not a picture of the program. In fact I don't know what it is a picture of.

I cannot upload an .vi file so I took a screenshot of my program :o :o :o :o

Why would you want to upload a .vi file?

Arduino programs are in .ino files.

What software uses .vi files ?

I am using Labview with LINX package to control my 5 servos

What about your Arduino program ? This, after all, an Arduino forum ...

I know but when you use the LINX package for labview you don't need an arduino code.

Not quite true as without the appropriate software the Arduino would do nothing.

A LINX support forum would seem to be a better place to ask for help.

another one ask the same question in the github forum which is a forum for linx package and no one answer :confused:

How about Hobbyist Toolkit - NI Community

It must have taken me at least 10 seconds to find that
