Custom font size on GLCD (Almost solved)

[bercioiu]

Hi all!
There is a way to print very large font (only numbers, see picture) , on a GLCD 128x64 oled i2c ssd1306?

Thank you!

What changes need to be made to modify an existing font? I tried to print in lines and points but it's almost impossible, there are over 8000 pixels ...
Thank you!

It might be easier to create the digits out of rectangles?

[bercioiu]

Understand from your answer that there is no way to change the existing font?
Do you imagine how many x,y (rectangle) I have to put for all 4 digits?

[LeighM]

From your image it looks like you want 7 segment digits?
In which case you could create a macro that draws a digit with 7 rectangles?
So the macro would have as parameters, the digit to display and the offset/position on screen.

I tried but there is a problem, how do I delete the previous segments to print the new number?

Several solutions:
1) Clear the screen and redraw everything,
2) Draw the segment using the background colour.

Thank you for your reply!

1) In the upper link is a video with clear screen.
2) Can not draw rectangles with the outline of the background color

You should be able to use macros 'SetBackgroundColour' and 'SetForegroundColour' to change the drawing colours before calling the DrawRectangle macro.

I think I'll quit. I'll finish the project with Arduino. With Arduino I can do any fonts that I want...

That way you won't get the sense of achievement when it's all working

It sounds like your very close. Post your program so far and we will be able to help.

Variable fonts is something we are considering but getting them right is tricky. We could however offer more scaling options without too much effort.

I'm getting closer
The refresh of the segments is a little weak, but given that they are "drawn" I will live with them ...
