@polychrome Man all I want is GPIO without having to program a microcontroller :(
Dozens of ports for all kinds of peripherals, all that insane computing power… but you can’t just send a signal over a wire. Fuck modern PCs. At least the old ones had parallel ports you could abuse.
@dredmorbius @lachs0r anything at all. The difference from other ports like USB is that it's completely manual and has direct influence over the "powered on" and "powered off" state of each pin so your code has full control over what is happening. Can also be good for low latency input like joysticks.
It's pretty great if you're a programmer.
i would imagine the hardest part is finding relevant and up-to-date documentation for these interfaces, but i'm also fairly confident that whatever TLDP has in a HOWTO is still 100% accurate because this stuff hasn't changed, and unlike floppy drives they're still actively used and maintained.
personally i stopped doing this stuff after frying a 2nd daughterboard in ye olde 486 twenty years ago.
Tōhō, socialism, and a cute mouse.
