Build complete but

[S_Bang]

Hi. Build complete, but - no numbers in the number display below the dial
Possible cause? Any tips? Phone is charged and lights up as per the manual when switched on.
Buttons, they are very rickety and prone to sticking/vanishing inside the shell, even though the phone shell is snug all round. Should they have some sort of padding or something to make them sit flush? Or are they supposed to be glued in place?

Also, a blue flash each time the dial reaches completion/fingerstop, this is correct?
Back display/e-paper looks to work ok, all letters intact/the legend with Rotary Unsmart Phone.

I think you have a phone with Justine's old firmware preloaded. It might help to first flash our new rewrite of the firmware. The instructions are here: https://docs.google.com/document/d/e/2P ... orLRnM/pub

Hi
I get the following error message:

Global variables use 9 bytes (0%) of dynamic memory, leaving 8183 bytes for local variables. Maximum is 8192 bytes.

Any tips on where I go wrong?

Hey, so sorry for the delay on this. I haven't seen this issue before. Could you show us the contents of ".../Documents/Arduino/hardware/MegaCore-master/avr/avrdude.conf"? You can upload it to e.g. https://paste.rs/web so I can take a look.

I wasn't allowed to paste the Arduino code into the link above. Too big it says.
I can of course send the file, but where? : )

Just wondering before my next attempt, is the firmware on the linked github site the latest update?

- Also, any tips on the flimsy buttons, I am thinking to go with a very thin rubber pad underneath each?

All the best, Sturla

I don't know but the development notes seems to need an update? Or else I am just daft, that may well be.
- Install MegaCore by MCUDude:
Follow his very easy instructions here: https://github.com/MCUdude/MegaCore#boa ... stallation
This does not work, Arduino cannot find it. The only Mega I can find is Mega 2560 - I suppose this is not it?
Arduino 2.3.4 ists ATmega1280 under Processor, but under boards it lists Arduino Mega or Mega 2560.
- MegaCore-master - even when I download, unzip and put it in the Hardware folder, it does not show in Arduino boards
The libraries:
- SD
- Adafruit BusIO
- Enableinterupt (must be downloaded as a zip)
are installed ok
- GxEPD2 - Arduino says it is installed but it could not find its dependencies?

And, - I cannot find any options to verify the settings:
-Configure the board settings for the RUSP:
