On one hand, it's satisfying to have brought something from conceptualization to fruition and be able to use the finished product. On the other, I get tired of it quickly and want to move on to the next thing.
Only finding that next thing isn't easy for me - the illusive inspiration necessary to find something engaging without being overwhelming.
I'm the type that has to spin a lot of plates and keep myself occupied. I'm always creating something or other or I get bored. Between projects is a hard place for me to be.
Right now work is sparse too, and while I welcome the break, the timing of it could be better. I wish I had 3 side projects right now. I don't even have one now that Winduino has a bow on it.
Meh.

I sort of have that. I've got my graphics and UI libraries. Issue is I'm stuck.
I'm missing a major feature, and that is anti-aliased draws (excepting TrueType and SVG which are).
The issue is that when combined with alpha blending (semi transparent draws) it becomes really tricky because you can't draw the same pixel in the same place twice - ever or it leads to artifacts as the pixel effectively gets blended with itself thus halving the transparency.
I can't find algorithms to do it properly+efficiently, outside of LVGL and I don't understand the LVGL code to do it, even looking at the documentation and pouring over the source. It uses some kind of masking technique that I don't understand at all.
Without that feature, it makes little sense for me to provide a full suite of controls for my UI library, since I will have to rewrite them all to use anti-aliased draws, and without it they look pretty ugly.
The whole thing is a bit overwhelming so I've been avoiding it.

I'm working with pixel buffers and "writeable bitmaps" which totally abstract me from the hardware. My productivity is what keeps me going when things get to be a slog ... while new ideas / enhancements are purcolating. And I remind myself it's (partly) the journey.

I wrote a pixel template that allows you to define its binary footprint and color model using a series of "channel_trait" template instantiations that define the channel properties. Many pixels have R G and B channels, but it's not limited to that. Defining each channel individually to make up a pixel allows me to support virtually any binary footprint and color model. I made a brief pixel declaration in my Winduino example for my GFX lib to write out in DirectX native 32bit BGRx format.
From there I wrote a bitmap template class, which is basically a variable that holds pixel data. It can be written to as it itself is a draw target (both draw destination and draw source) or read from and applied to other draw targets. It's templated by the type of pixel (as above, for example RGB565) and the type of palette (if any)
It's so abstract I can support other formats and screen styles by changing barely anything. All my draw routines take pixels in any format and do behind the scenes conversion transparently (w/ alpha blending as available and called for)
I've written whole applications, only to have the screen hardware changed on me last minute. Takes me minutes to update, if I already wrote it to be resolution agnostic (which I typically do)
Here's a series of pixel declaration templates for color models of various types (including grayscale and indexed/palleted pixels) non-exaustive, just so you can see what it looks like:
template<size_t BitDepth>
using rgb_pixel = pixel<
channel_traits<channel_name::R,(BitDepth/3)>,
channel_traits<channel_name::G,((BitDepth/3)+(BitDepth%3))>,
channel_traits<channel_name::B,(BitDepth/3)>
>;
template<size_t BitDepth>
using rgba_pixel = pixel<
channel_traits<channel_name::R,(BitDepth/4)>,
channel_traits<channel_name::G,((BitDepth/4)+(BitDepth%4))>,
channel_traits<channel_name::B,(BitDepth/4)>,
channel_traits<channel_name::A,(BitDepth/4),0,(1<<(BitDepth/4))-1,(1<<(BitDepth/4))-1>
>;
template<size_t BitDepth>
using gsc_pixel = pixel<
channel_traits<channel_name::L,BitDepth>
>;
template<size_t BitDepth>
using yuv_pixel = pixel<
channel_traits<channel_name::Y,((BitDepth/3)+(BitDepth%3))>,
channel_traits<channel_name::U,(BitDepth/3)>,
channel_traits<channel_name::V,(BitDepth/3)>
>;
template<size_t BitDepth>
using yuva_pixel = pixel<
channel_traits<channel_name::Y,((BitDepth/4)+(BitDepth%4))>,
channel_traits<channel_name::U,(BitDepth/4)>,
channel_traits<channel_name::V,(BitDepth/4)>,
channel_traits<channel_name::A,(BitDepth/4),0,(1<<(BitDepth/4))-1,(1<<(BitDepth/4))-1>
>;
template<size_t BitDepth>
using ycbcr_pixel = pixel<
channel_traits<channel_name::Y,((BitDepth/3)+(BitDepth%3))>,
channel_traits<channel_name::Cb,(BitDepth/3)>,
channel_traits<channel_name::Cr,(BitDepth/3)>
>;
template<size_t BitDepth>
using ycbcra_pixel = pixel<
channel_traits<channel_name::Y,((BitDepth/4)+(BitDepth%4))>,
channel_traits<channel_name::Cb,(BitDepth/4)>,
channel_traits<channel_name::Cr,(BitDepth/4)>,
channel_traits<channel_name::A,(BitDepth/4),0,(1<<(BitDepth/4))-1,(1<<(BitDepth/4))-1>
>;
template<size_t BitDepth>
using indexed_pixel=pixel<channel_traits<channel_name::index,BitDepth>>;
You then use them like
gfx::rgb_pixel<16> px = gfx::color<gfx::rgb_pixel<16>>::purple;
px.channel<gfx::channel_name::G>(31);
float r = px.channelr<gfx::channel_name::R>();

 There's more than a grain of truth to that.

I don't argue with electrical engineers - at least about their field.
I'd as soon argue with a theoretical physicist.
Totally out of my element - foolish of me to think I should.
I just work with 'em. There is one I work with that's kinda difficult, but I think it's mostly because he's looking to retirement and his priorities have shifted away from work.

In my early career I worked with many EEs and they can be difficult, but I got along with them fairly well.

Most of the ones I worked with were of the opinion that they were right until proven wrong.

So do I. The biggest difference between me and others is, that once proven wrong I have no problem at all to say "Sorry, I was wrong" and accept the new truth.
I just have big problems with "because I say so", "it is like that" and other not so useful arguments

Lots of laws are that way, too. It is forbidden because you shouldn't do it. It hurts nobody or nothing, but you just ain't supposed to!

I forget the details, but I'm somehow reminded of some debate sparked by some art exhibit that perhaps (it was being argued) "went too far".
A judge was asked how he told mere nudity apart from porn, and his best answer went along the lines of "I know it when I see it". Which sent a pretty bad message IMO considering it came from someone whose job it is to interpret the law. Laws shouldn't be vague.

The most recent case of funny lawsuits (well, the case hasn't reached the courts yet - The last I heard was that the criminal wasn't yet caught) is whether indecent exposure to a car is against the law. Noone saw it happen, late at night when a young man entered the parking house, empty except for the cars, and flashing himself to a parked Tesla. He obviously knew that a Tesla has cameras recording whatever happens around the car, even when parked and seemingly completely turned off.
The owner of the car didn't look through the videos until a couple of days later, to discover the naked young man who obviously was aware of the cameras. So the legal question is: Can you be fined or thrown in prison because a car saw you flashing yourself?
Note that Internet wasn't involved. If the image was transmitted over the Internet and the man had touched himself, the viewer (here: the car owner) would have been arrested. Provided, of course, that the viewer was a male. If the flasher was below 14 years of age, the car owner would have been arrested for raping the child. That is in Norway - I hope that it is not common in other countries.
