The first time you call getArrayFromCSV it reads lines until it gets to the end of the file. The second time around it's already at the end of the file, so there are no more lines to read.

You can fix this either by reopening the file before each call, or by refactoring your function to pull out all the data you need in one pass.

I drew some inspiration from svgtoeagle when I was putting this together ☺️

Adding an option to output draw calls directly would be easy enough. The only downside is that the draw calls wouldn't allow for convenient on-the-fly translation/rotation/scaling.

Having a page for this on espruino.com would be great ☺️. I'll see about adding it to the EspruinoWebTools repo when I find the time.

I made a tool to convert SVG files into a format that's easier to render on a Bangle.js. Just feed the SVG through the converter, paste it in your source file, slap in some rendering code, and away you go!

The converter itself is moderately limited, but it should work for simple graphics. It basically converts all the shapes in the SVG into lists of points that can be fed to drawPoly or fillPoly.

I won't be able to test this outside the emulator until my smart watch arrives, so I would love to hear reports as to how well it works :)

An other approach would be to save the time when the timer was started, and calculate elapsed time from (current time - start time) when the widget is loaded. That would allow the timer to keep track of the elapsed time even when the widget is not loaded.

Yeah, that would be better. But how can I detect that widget is being dismissed?

Would the the E.on('kill',...) event work? (see https://github.com/espruino/BangleApps/blob/master/README.md#misc-notes)

Bangle.js doesn't support 4 bit RGBA - it assumes that all 4 bit images use the Mac palette. You can see what color formats are supported here: https://www.espruino.com/Reference#l_Graphics_drawImage

I'm afraid this isn't a full app yet. My smartwatch hasn't arrived, so all I can do right now is experiment with the emulator. When it arrives I will for sure keep working on this and try to get it included in the app loader.

Canada here. Mine shipped on March 27th, and there have been no tracking events whatsoever. The Royal Mail tracker still says "Sender preparing item".

This would override the GB function if it's already defined, correct? What if multiple apps want to receive events?

That would be super handy - I actually created SVG versions of most of the weather symbols while I was contemplating how to render them, so an SVG to Espruino draw call converter would have been perfect. I imagine you'd have to pick a subset of the SVG spec to support, though.

Another possibility would be to create a simple web-based vector editor with the limitations of the Graphics API in mind.

I've been having fun making a sort of mock up in the emulator with randomly generated weather :)

Sounds like it. See here: https://codeberg.org/Freeyourgadget/Gadgetbridge/wiki/Weather

Nice! That sounds a lot more straightforward than I was expecting.

When my watch arrives I was thinking I might see about creating a simple app or widget to tell me the current weather. Has anyone else started on anything like that?

Also, if I were to create such an app, what would be the most straightforward way to get current weather information onto the watch? I see that GadgetBridge supports weather for some other models of smart watches, would it be possible to take advantage of that?
