#uxn (opctest.tal) on #pocket386

#uxn peeps,

Why are [] runes no longer used around label runes?

The #compudanzas guide used to have label runes like this:

|00 @System [ &vector $2 &pad $6 &r $2 &g $2 &b $2 ]

but now the uxn tutorial looks like:

|00 @System &vector $2 &pad $6 &r $2 &g $2 &b $2

for exactly the same example programs.

@rl_dane @mdc I wonder how #uxn opcodes compare to what F18 chips from #GreenArrays have.

Only 32 opcodes, 8 of them special (can be used in th last 3 bits of a kind of 18-bit #VLIW word) versus 256 opcodes of #uxn

#varvara offers much more high level i/o, F18A has 4 interchip ports, GPIO, A/D interface and SERDES, which can be used to build things like Ethernet for example.
varvara-fpga does not implement most varvara I/O features at all.

AFAIK, there hasn't been a hardware implementation of #uxn thus far.

The instruction set is pretty simple, the core is just 100 lines of C. I'd surmise it could be implemented in the very dinkiest #fpga, and using some kind of TTL asic or something (I'm way, way, way beyond my competency, here (and almost everywhere else, lolol)) should be quite doable.

Of course, stuff like graphics would be more complex, as it gives you any 4 colors out of a range of 4096, and the display size can be variable, but it's been implemented on reasonably limited hardware like the #PlayDate and Gameboy Advance.

I'm kind of wondering if anyone has attempted a true 8-bit implementation, like on a #Commodore64. XD

The cell-based coloring system of most 8-bit micros would be challenging to adapt uxn to, unless you just assumed monochrome.

Now I kinda want a small [Potato] plushie or something I can talk to while learning #uxn. XD

Rek's cartoon anthropomorphization of Potato (obviously inspired by form factors like the #Macintosh IIsi and earlier mac models) hits me right in the feels. XD

🌻 Implemented a dialect of tiny-BASIC in #uxn, it has full graphics and mouse support in 4kb. I'll work on improving it in the next few days.

Just a neat little idea and finished it, I made little Digital Business/Contact card in #uxn

inspired by @angelwood i created a #uxn contact card for myself

output of a uxn rom to produce a card with contact information on it. the contents are:

there is ASCII art showing a flaming sword, trees, mountains, clouds, and the moon. — output of a uxn rom to produce a card with contact information on it. the contents are: eiríkr åsheim d6@phial.org @d6 at merveilles.town plastic-idolatry.com/erik there is ASCII art showing a flaming sword, trees, mountains, clouds, and the moon.

I went through @compudanzas uxn tutorials once, had fun, and forget everything again. So I did it again, but this time I tried to make some literate programming style notes about all the different aspects I'm picking up. I'm through with my second attempt and I have to say that it was worth the effort. At least the basics stuck now (or so he hoped...)

The notes can be found here but I haven't cleaned up anything yet. I'm pretty sure I have some conceptual mistakes in there as well. The format is also not very consistent along the notes, since I lost patience with myself at times.
