The little mouse
-
First the little mouse wanted an epub reader Then she needed a zip library to unzip the xml Then she needed an XML parser library to decode it. Then she needed an HTML library to display the content. Then she needed a CSS library to lay out the HTML Then she needed a truetype font library to render the CSS styles *sigh* If these were designed for little CPUs why did they make the technology stack so deep? :confused: :doh:

Or, the little mouse would just check out the fantastic (and 100% free) calibre reader[^]. :-D And also FOSS (GitHub - kovidgoyal/calibre: The official source code repository for the calibre ebook manager[^]) you can join the project too. It really is great software. i've been using it for years now.

not sure it will run on a WROVER chip though

Oh...I had not seen that requirement. :)
I didn't list it in the OP. My bad. The thing is too, that looks like an e-book manager more than a reader. I want this thing to run on a ESP32 @ 240MHz with 4MB of PSRAM, 4MB of flash, and 512k of actual RAM, with a 600x448 7 color e-paper display. It's a tall order, to be sure. Especially processing CSS layouts and HTML. TTF support is no joke either though. This is a project and a half. However, as I'm building it I intend to develop a user interface library that is HTML based for producing more professional screens on these little IoT widgets.

That sounds cool. Maybe some of the code that renders the e-books in calibre could be leveraged to give you an idea how to do that work?? But, maybe not-- since I think the calibre code is in python. Isn't it interesting that this is about re-use -- one of the holy grails of programming that has been around forever -- and we're still talking about it in 2021? A few years ago another dev had a HTML to PDF thing in their code. I said, "hey, can I get that code so I can just create PDFs from my HTML..." I love being naive. So, then i looked at the code and everything was tied to everything else and there was no way to use the original code without copy / paste. and even then there were dependencies. so, yeah, reuse...wish it were already done once but we just keep on reinventing wheels. :rolleyes:

I have an open source project that is an e-book reader that targets the ESP32 and does most of this so I'm using it as a reference. I'd use it entirely except: 1. I can't get it to build 2. I want to use its component features like HTML/CSS and truetype rendering in my GFX lib without necessarily using EPUB 3. It has no knowledge of color e-ink displays and only supports one device anyway, which i don't own. But at least it has given me a ton of ideas, and let me know of projects out there I didn't think would build on the ESP32 (but they do, because it uses them!) like freetype.
