number of characters per line

Hello again,

since "Terminal" does not seem to work on the emulator, I'm currently experimenting with text output using the graphics object itself.

This is why I wondered how many characters one could show per line using the default font (see this Gist, which you may also immediately load into the emulator and run).

The answer is: you can show 60 characters per line!

This means just 4 pixels per character (including spacing!)

I do not know how it will look on a real device, but it seems still readable on my desktop (ok, I have to admit, it uses a retina display...)

Yep, it's reasonably readable :) Thanks for the gist + emulator links - they're really helpful :)

Ah well,

what is really, really helpful is that you implemented that feature into your emulator!!!!

Thanks a lot for all your effort!

(now I'm eagerly waiting for my first Bangle.js device)

@Andreas_Rozek: Isn't it 40 characters (not 60)?
Meaning 6 pixels per character including 1 pixel spacing.

Well,

it WAS 60 when I first tried it (that's why I was able to print a complete ASCII table on the display) but, it seems as if the default font would have changed recently.

@gfwilliams: did you change default settings when updating the emulator? How can I explicitly set the font I used yesterday?

[EDIT] I meanwhile found out, that calling

  g.setFontBitmap();

will change everything back for my test (Gists have been updated accordingly). Normally, switching to the larger font might be a good idea - as long as developers know that they could display more text, if necessary.

...made a cheap terminal a while ago (on a different, but comparable display)... text goes around... http://forum.espruino.com/comments/12605583/

Wow, great - thank you very much!

Ahh - yes, it's because I modified the Emulator to use more of Bangle.js's code - which sets the font from 4x6 to 6x8 by default.

I'm trying to move more towards g.setFont("4x6") as g.setFontBitmap() isn't as obvious :)

Thank you!

I've updated my Gists accordingly.
