Communication with Arduino MEGA and Firmata, can't read from above pin 13

in Integration and Hardware • 1 year ago

Hi,

I'm working on an installation with 16 buttons and 16 leds. I set it up with an arduino Mega. Now I try to communicate with firmata. I tried first with Firmata Test, and this works well, I can read from all digital Inputs.

But if I try it in my own script, I can't read from my digital pins. I've found some posts about a problem of the Firmata to read the digital pins above 13.

I can send output to all my pins, but not read from them.

Has this been solved somehow? Has anyone a solution for this? Or an idea what to do?

Thank you for your help!

Hi,

I just got an answer from a developer:

The processing firmata client does not yet support the arduino mega board. It is currently hard coded for the standard (atmega328 - based) arduino boards which is why some features work with the mega and others don't. The processing firmata client needs to be rewritten to use the configuration query rather than hard code pin numbers.

This is quite a bummer. So I wanted to ask to the forum here, ist there another simple library I can use, to read and write to an arduino Mega1280?

Thank you!
