Can someone get me up to speed with Kobo development?

[xfbs]

Dear Community,

Could someone get me up to speed with developing apps for Kobo (specifically Kobo Glo)? I bought one for cheaps, planning to just glue it to my wall and use it as a fancy calendar or something like that.

Tiny setback is that I bricked the touchscreen while setting it up, but that's cool because I wasn't planning on using it anyways.

I've poked around a little bit and found that it uses Qt, specifically Qt 5.2. Is there a tutorial on how to get set up with Qt for arm (embedded)? Just like a hello world kind of situation that I can tinker with?

Also, how much of the default system can I delete? I mean I have a backup of anything, but is there a tutorial on how to just throw everything away (I don't need any of the default GUI stuff, I want it to boot right into my app).

For the wifi: I found some references to wpa_supplicant, am I right in assuming that it's using that to connect to wifi? If so, I think I can probably just hardcode my wifi into the config, and in case it changes I can manually edit it, right?

Cheers, xfbs!

You might want to check out Github projects for Kobo devices. Projects like KOReader include help in setting up proper toolchains for the devices.

Luck;

Of course, that repo (at https://github.com/kobolabs/Kobo-Reader) was super helpful. So you think it's a good idea to look at other projects to see if they have any guides on getting set up properly? There's koreader, okreader, kobo-hack, plato and also this thread from what I could find thus far.

KOreader is a bit extensive. Depending on what you want you really only need to take a look at some of the drawing stuff:

(probably not exhaustive; just some quick links)
https://github.com/koreader/koreader...i/einkfb_h.lua
https://github.com/koreader/koreader...fer_einkfb.lua
https://github.com/koreader/koreader.../einkfb_decl.c
https://github.com/koreader/koreader...clude/einkfb.h

Relevant stuff for Plato: https://github.com/baskerville/plato...rc/framebuffer

okreader doesn't include any GUI stuff afaik

But what do you mean by fancy calendar? You can easily display image and HTML files with what's included in KSM and a little scripting.

Also, how much of the default system can I delete? I mean I have a backup of anything, but is there a tutorial on how to just throw everything away (I don't need any of the default GUI stuff, I want it to boot right into my app).

Just set starting your app as the default in KSM and leave the rest alone. Well, unless you just really, really, really want to get rid of Nickel for some reason but I generally wouldn't. In that case you could replace it all with okreader.

Edit: but if you like Lua, you could also take KSM + KOReader as a base, whether to display generated images or to create your own widgets. http://koreader.rocks/doc/modules/ui.widget.widget.html

In that case you could create a plugin, see some examples here: https://github.com/koreader/koreader...033cfb/plugins

You could do something similar with Plato if you like Rust, I suppose. :P
