We have designed a fix for the Defender missed reverse problem , here we offer the solution for anyone building a Defender game based on a MAME system.
The encoder has up to 24 digital inputs, and a corresponding number of earths (and +5V pins, handy for optical devices). We offer it with MAME standard keys, or with our modified key mapping (ALT,CTRL not used), or we can program with your custom keys. The encoder has a micro-usb socket ( it is thru-hole soldered at 4 points, so is not delicate like some arduino clones).
At some point there will be an instant shop offering some standard configurations, but for now you can email us with your requirements, be sure to list every button and other controls that you want to use: email us
We wire our panels using dupont connectors at the encoder, and dupont at the joystick if possible, eg JLF-01 or LS55-01, otherwise solder at the controls. We don't daisy chain earths, so each switch has 2 wires going back to the encoder.
£22 24input encoder with dupont headers: 14inputs, 14earths, 4x5V
£24 24input encoder with dupont headers: 21inputs, 21earths, 4x5V
£25 24input encoder with dupont headers: 24inputs, 23earths, 4x5V
15p 40cm Dupont female to female. Use as is, or cut and strip ends to make 1 or 2 connection wires.
10p 30cm Dupont female to female. Use as is, or cut and strip ends to make 1 or 2 connection wires.
10p 20cm Dupont female to female. Use as is for eg JLF-01.
