g.setFontPBF not working?

[YuukanOO]

Is there something special to make PBF fonts work on Bangle.js 2 (firmware 2v25)?

I tried uploading the renaissance ones (from here https://github.com/Chriz76/renaissance/tree/master/fonts) using the espruino library with:

npx espruino -d Bangle.js --storage renaissance_18.pbf:renaissance_18.pbf

and using them with:

g.setFontPBF(require("Storage").read("renaissance_18.pbf"))

but nothing shows on my Bangle. No error and no text displayed 🤔

Did I miss something?

This should work - in fact on latest builds we're using PBF fonts by default. Do you think you can try using the IDE?

First verify the the font is actually there according to the Storage menu in the IDE, then see whether require("Storage").read("renaissance_18.pbf").length shows the correct length in the REPL?

But if you install a cutting edge firmware build then several PBF fonts will already be built in... https://github.com/espruino/Espruino/tree/master/libs/graphics/font

There's a temporary issue (Python/Pip/Nordic have changed something and have broken the automatic build for Nordic devices) but you can get the last working curring edge firmware from https://www.espruino.com/binaries/travis/9d1d889905d3c05d997cb9df67d7c71712df4e01/

Removed the file on my Bangle, re-uploaded it with:

espruino -d Bangle.js --storage renaissance_18.pbf:renaissance_18.pbf

Hmmm, strange... Looks like there are 20 bytes missing?

ls -l renaissance_18.pbf 
-rw-r--r--@ 1 julien  staff  8667 May  5 22:19 renaissance_18.pbf

Tested with this code:

g.clear();

g.setColor("#fff");
//g.setFont("6x8");
g.setFontPBF(require('Storage').read('renaissance_18.pbf'));
g.drawString("Hello", 0, 50);

What about uploading with the IDE? Does that include the right number of bytes?

[YuukanOO]

Ok it works using the IDE! Same size and the text is displayed. Maybe I did something wrong using the espruino module?

[gfwilliams]

Ok, great. I've just updated the command-line tools to versiion 0.1.60 - maybe that'll help?

I just looked and the tools were loading the file as if it was a UTF8 file, but it was just binary. I think that's likely why the file size changed and the file ended up corrupt? Likely Bangle.js just silently bailed when it found the font wasn't right

I'll try and let you know ;) A huge thanks to you! Bangle is great ❤️

Can confirm it works with [email protected]!

Great - thanks for letting me know! (thanks for the donation too - that's awesome!)
