monochrome, and any dimming is done by dithering. I'm so glad
I'm liveblogging this so everyone can see how stupid I am.
</p>
+ <p>
+ That's ok though! We're here to learn, and this actually makes
+ things relatively nice and easy. I'm sure there are monochrome
+ image -> uint arrays somewhere out there one the web already,
+ thisn is a very common format on embedded platforms, so I just
+ need to find one and run the icons for various perks etc through
+ them, and we can get one displaying.
+ </p>
+ <p>In fact, maybe that's what we do next. BRB...</p>

+ Excellent, here's one, first hit on google.
+ <a href="https://javl.github.io/image2cpp/">image2cpp</a>
+ Let's run the Cherchez La Femme image through it and upload it
+ to the machine aaaand...

+ />
+ </a>
+ <p>
+ So, that's not good. In fairness, I am loading a 167x167 bitmap
+ into memory here, I suppose it makes sense that that wouldn't
+ exactly work. But it is going to make this more difficult.
+ </p>
+ <p>
+ Next question then. What is a reasonable maximum array size we
+ can use here? Time to experiment. We'll start with half the
+ resolution, 83x83.

+ </a>
+ <p>
+ OK, it's displaying, but that's clearly not right. Here's what
+ it's supposed to look like:

+ <a href="../img/projects/pipboy/CherchezLaFemme.png">
+ <img
+ class="blog-img"
+ src="../img/projects/pipboy/CherchezLaFemme.png"
+ alt="The Cherchez La Femme perk icon from New Vegas"
+ />
+ </a>
+ <p>
+ That's ok though, there's options on the converter for just this
+ predicament. This was the default (Horizontal - 1bpp), and
+ Vertical - 1bpp landed similar results, so let's move on from
+ that converter and use the one hosted on
+ <a href="https://www.espruino.com/Image+Converter"
+ >Espruino's website</a
+ >
+ instead. Man I'm really proving myself soooo smart today.
+ </p>
+ <p>
+ Using the right tool for the job gives us this! And it's even
+ full resolution! Huzzah!

+ </a>
+ <p>
+ OK, that's real, genuine progress. We can encode images and
+ display them, which we need for the perks screen. They are
+ pretty big though, so I think next order of business is going to
+ be keeping those strings in text files and loading them in when
+ we need to. Back to the docs... Although I might leave it there
+ tonight, my back hurts. No wonder Zuck had to be 19 to do this
+ live.

+ <p>Evening! Let's get right back to work.</p>
+ <p>
+ Yesterday, we figured out how to correctly convert and display
+ an image on the screen. Today,we're going to figure out storing
+ those images, loading them at runtime, and switching to another
+ image later.
+ </p>
+ <p>
+ So, first up: storing and loading the image. This is gonna need
+ me to look up how the espruino fs library works. BRB...

+ <p>
+ Well that was tremendously easy. First try baby, finally I'm not
+ completely stupid about something! We're gaming! I would take a
+ photo of the screen but I didn't change the image's position so
+ it looks exactly the same. but rest assured it is there!
+ </p>
+ <p>OK, next up, we swap images on the fly.</p>

+ <p>
+ Done! Again! Wow we're going win after win today. Apart from the
+ weird bit of artifacting in the top left of the image there,
+ but, er... I'm sure that's fine. Let's ignore it for now. We'll
+ see if it continues with other images.
+ </p>
+ <p>
+ OK, so this is actually a fair cut through the work we need to
+ do here. So let's structure the screen a bit, and add the name
+ and descriptions.
