New mobiflight version

[jovial copper]

hello, I updated my mobiflight, where is the interface to create new buttons on my arduino board please ?

[pliant oasis]

It is in settings

thanks

A Nano has 18 pins... where did you intend to wire additional buttons?

[stuck plank]

please write 🙂

I will use a multiplexer

I put this screenshot here just to show the window I m looking

[stuck plank]

so if you want to add the multiplexer you need to remove some of the existing devices to free the pins for the multiplexer

[jovial copper]

Yes, I should have succeeded, I'll order the PCB soon. The diagram might be a bit chaotic cause im beginner

Is it okay if I use analog pins as if they were digital? (here, pins A0 and A1)

[brave pivot]

Yes, except A6 and A7 on a Nano. Those are only good for analog input. Nothing else.

[stuck plank]

yea those are free

[jovial copper]

Yes it was the error I did on my precedent pcb

[stuck plank]

so hmm, is sw11 only one side?

[brave pivot]

A single 16-bit multiplexer will need four address lines plus one data pin.

[stuck plank]

you can put the "x" marks on the unused pins so kicad will not complain in the "design rule check"

[jovial copper]

what do you mean ?

[stuck plank]

it is only connected on one pin

[jovial copper]

Yes it'sON-ON switch

[stuck plank]

yea so only one function needed

the others are three position?

[jovial copper]

Some are 3 positions, others are 2

[stuck plank]

ah true

wasnt looking hard enough

also see the green note on the multiplexer page on docs

"In electrically noisy environments, a pull-up resistor can be connected between the microcontroller’s supply voltage and SIG to increase signal reliability. Use a 10kΩ resistor to +5V with 5V data signals, and a 1–5kΩ resistor to +3.3V with 3.3V data signals."

[brave pivot]

ON-ON switches generally only need one pin connected.

[jovial copper]

yes GND and 1 pin

[jovial copper]

thanks I will do it

[brave pivot]

because Mobiflight can detect the Release status

[stuck plank]

so you might as well do the 10k ohm pullup to 5V

btw, one tip that I am using that makes the wiring easier

I use the global labels

then I do this

just need to use the same names

it is waaaay easier to move pins around if needed

[jovial copper]

Thanks for the tip !
