Hi, I saw in this new version now there is the possibility to use up to 68 buttons (new pins) with Arduino Mega.Thank you fro this amazing update!

I have a very stupid question where I have not find the answer nowhere.

Arduino mega has 53 digital pins. In mobiflight I can see I can only start from pin number 2 (0 and 1 are not in the list). This mean digital pins usable are 51.
Then with this new version I assume I can use also the analogic pins (starting with A0). Arduino mega has 15 analogic pins. I assume I can use now all of them. So, 51 digital pins +15 analogic pins = 66 in total (I have not counted the pin 0 and 1). Am I right?

So, in this case, since in mobiflight the selction of pins are only numerics, I assume that the pin 54 match the physical PIN A0 of the Arduino mega. AM I right?

THank you so much!

Best Regards, Antonio.

Hi Antonio,
An Arduino Mega has 70 I/Os numbered from 0 to 69. 54 digital and 16 analog. Digital from 0 to 53 = 54 and analog from 54 to 69 = 16 (A0 to A15).
In MF there are 3 pins not usable: number 0,1 and 69. Number 0 and 1 are reserved vor comunications, number 69 was forgotten to implement. So you have 67 I/Os in total for use.

You are absolutely right! I'm started to count the A0 like a null pin

Thank you for clarified me this! absolutely helpful!

Thanks again!
