Hope anyone could do this, because I can’t get it to work and I think this is also a very good feature. I want to use this to display text to LCD.

Thank you.

Hi jmlapido
I have started a library very similar to this with the ability to save and retrieve individual settings and log data from a file. Is this something you would be interested in?

Hi bradzilla84,

Yes, this would be very similar… Hope you could share me that library…

Thank you

Hi mate…

Any update?

[bradzilla84]

Sorry not yet, I have a fair few projects on the go at the moment and this one will be a bit one.
