JVSy: open source JVS I/O to PC interface (help wanted for analog and lightgun)

[k4roshi]

Hi guys, just wanted to let you know about my little project.
It's a JVS to PC adapter, a-la JVS-PAC. It converts the inputs from a jvs cabinet to a HID joystick. Works on pc, mac and linux, it could be made to work on PS3 too if needed.
For now it only recognizes digital inputs, but i'll start working on analog soon.
It's open source and uses a teensy board with a rs 485 chip. It's quite cheap: the teensy is about 16$, the sn75176b (for rs-485) is about 2$ for 4 ICs.
You can find the source here: https://github.com/k4roshi/JVSy
If you'd like a compiled version, just ask

This is pretty cool. any vids or photos? pre-compile windows version would be nice too

Hi guys!
I updated the code on github, improved the startup procedure, coin handling works and shift mode is provided:
p1 start works as shift, when pressed with the following buttons it causes different keypresses:
button 1: coin (presses keyb 5)
J1 right: Tab
J1 down: P (pause)
J1 left: enter
P2: esc

Here's the binary build:

I also managed to read analog inputs, but have no way of "calibrating" them.
This debug build outputs to the serial console the binary readings it receives from the analog ports. If anybody wants to flash this and report back to me i can make them work in little time. This doesn't work as a joystick input, so don't flash unless you know what you're doing.

I studied a bit the lightgun controls and they should be easy to implement, but again, i would need someone to help me test it.

I was actually going to be messing around with something similar so will be able to help out with analog once I have it set up. Great work so far!
