Questions about the firmware…

[wendells01]

Hello, @max-arnold how are you?

I'm creating a firmware fork with a custom interface inspired by Yaesu transceivers and I would be very happy if you could answer some questions for me:

1- how is the source of the numbers inserted into the firmware? I saw that the font used is the orbitron light, but I couldn't understand where it is in the firmware and how to change it

2- how are the icons/graphic elements of the interface drawn? How can I insert a custom icon to indicate the ON/OFF state of a function?

3- I have in mind to add a blue gradient at the bottom of the interface, similar to the interface of Yaesu transceivers, would it be possible?

I created a sketch of how I imagine the firmware will look, here it is:
