I've not seen an assembly language that uses floating point before
Common in DSP processors. Did a DSP course where we used TMS320x processors back in the 90s. Had to write a pink noise generator in assembly. Don't remember much of it but I do remember there were lots of instructions for floating point arithmetics.

Fair enough. Just shows I've been at the bottom of the DSP food chain and only seen integer stuff!

Any least that means FV-1 SpinASM is a step *up*! Lol!


Edit: Using a floating point DSP for pink noise generation is cracking a nut with a sledgehammer. Here it is on a 8-bit integer chip: https://electricdruid.net/noise2-white-pink-noise-source/

Hey guys, I packaged the pk2cmd with the Platypus tool ( https://sveinbjorn.org/platypus ). Platypus created a simple drop-app for flashing hex files. At the moment it only works with 24LC32A chips, that's hardcoded for now. Tested by patrick398 and myself, seems to work. Future work includes EEPROM-chip-selector. Maybe  ;)

* Download here: https://www.dropbox.com/s/qyj9vtmetj6s0m9/Pk2mac.app.zip?dl=0
* Unzip
* Right-click -> Open (since it's not a signed app)
* Drop hex files on window

That's it!

if anyone else wants to program a 24lc32 on mac without a pickit2, i'll second vigilante397 about those $10 ch341 programmers on ebay. real easy once you have the libraries installed. worth noting that the pedalpcb fv1 flash tool is this free software from github, since you can find some extra info at the source: https://github.com/stefanct/ch341eepromtool

and thanks for sharing that tool, pruttelherrie! i'm planning to pick up a pickit2 to mess with, so i'm interested to see if that's even easier to use than the ch341 (which does require the terminal).

The programme pruttelherrie made is fantastic, really makes it so simple. Just just export the hex from spincad and drag it in the programme and it works like a charm every time
