I downloaded an old speedy version (201808) on another mega 2560 and used the same GPIO STD on the GPIO.
The same result....

@Dazq thank you for taking the effort. My knowledge on this subject is to limited. If you want something tried, let me know.

@Punisher454 I've read your thread, it seems to be the same issue indeed.

I have not given up on it, I have just had to put this project on hold while I finish up a couple other car EFI retrofit projects I'm doing for other people, I will come back to this one in the next few months when I get a chance to work on my own stuff again.
For this I have a 12.3" LCD in my v8 S-10 for the main dash display which is connected to an R-Pi running Tunerstudio and GPIO-STD, and on another LCD (10.2") where the radio used to go, that one also uses anther R-Pi/Tunerstudio and connects to the Speeduino. I'd really like to share a few items of data between the two displays, and hopefully I will be able to when the little truck is closer to finished (hopefully by the end of the year).

I really feel like I'm just missing something simple on the GPIO or something my be broken in speeduino or tunerstudio.

Yeah, I know...

I have the idea that I'm very close but not yet there but still learning

My next move is to connect resistors to all analog inputs and connect them to ground to see what this does.

Did you guys ever get this to work?

[punisher454]

I did not. But I also haven't tried since then either. Its something I'd really like to use, but i just have too much other stuff to do first.
I am always watching to see if anyone else has better luck.
