Would KADE work well for BYO paddles? (AKA, wiring up a couple paddle pots directly to a KADE)
Paddles:The problem with using the CX30 paddles with most analog encoders is that Atari wired them as variable resistors (2 wires - measures resistance) instead of voltage-dividing potentiometers. (3 wires - measures voltage)
"Pong Paddle" schematic and pinout is in the upper right corner
here.
Based on the schematic/pinout you can
probably add a ground jumper wire from the unused tab on the paddle pots to the pin 8 wire on the button.
That gives you 5v (pin 7), ground (pin 8 ), and wiper (pins 5 and 9), which is
probably going to work.
Haven't tried it yet -- might cause jitter sharing analog and digital grounds.
LMK if you want me to test this configuration.
KADE:MiniArcade and microArcade, the current generation of KADE encoders, use the at90usb162 or atmega32u2 AVRs which do
not have analog input pins. (digital or optical device inputs only)
KADESTICK, KADE+, maxArcade (prototype -- details in KADE Loader when you enable Beta updates) and the upcoming miniConsole use an atmega32u4 (or newer) AVR with analog input pins.
The KADESTICK AVR is
sold out at MattairTech and KADE+ is in beta testing and not currently in Loader.
If you want to "roll your own"
right now, I'd suggest getting the AVR used in maxArcade from MattairTech
here.
There are three firmwares in Loader:
-- USB/HID Joystick 2 Player with Analog (Beta) - each player has 4 analog axes, a d-pad, and 14 buttons
-- USB/HID Joystick 4 Player (Beta)
-- MAME 4 Player Encoder (Beta)
