Problem using Ramps 1.4 with LabView

Hey everyone I have already asked this question on the official NI forum and haven't gotten a reply yet, so I'm posting here to see if someone can help me with this.

I want to control Ramps 1.4 and move the X servo motor through LabView using the Hobbyist toolbox but I'm getting the 5005 error stating that Digital input channel 54 is not available as Arduino mega only supports up to channel 53 (see attachment for the error message). Is there any way to solve this problem?

... I was using the ArduinoDue (with RADDS boards) -- AFAIK, it could be used with a RAMPS board too, if the boards is modified to 3.3V power support for the Due ... but better check, if true ...

I'm sorry I'm not too knowledgeable about Arduino. Can you please explain how that board would solve my problem?

... the ArduinoDue has the same pin-layout as the Mega, but needs 3.3V insteaf of 5V.

Here a comparison between them - [www.educba.com]

look at official pin names [docs.arduino.cc]

the highest digital pin is 53

Digital pins 54-69 where not in the original specification

D54 - D69 are A0 to A15 in older implementations.



It would seem this is a well known issue [forums.ni.com]

use them as analog pins. setting values to 0 or 255...

... so even better!
