From 5291_MaintenanceLibrary.pdf p38:





In a useful format, that's:


--- Code: ---           D1  1      20  Ground
(missing pin)             -Strobe
           D2             Ground
           D3             D0
     (unused)             (unused)
     (unused)             (unused)
     (unused)             Frame Ground
           D4             +5V
           D5             Ground
           D6  10     11  Output

--- End code ---

Only one Ground pin needs to be connected, I used pin 12.

They look and feel better without the casing. Soarer, will try your controller  when is ready.

Awesome! Is the code you mentioned earlier available to look at?

Thanks so much for you knowledge on this stuff. I didn't think I'd get so much good info, glad you could prove me wrong.  :thumb:

Source code isn't available. I'm actually using my generic controller code, which I keep saying will be available 'soon', but I've had some interesting Real Work recently taking my time! It takes a config file to set it up, for this 'board it looks like:


--- Code: ---matrix
scanrate 1
debounce 1
blocking 0
muxstrobe_port PB6:0
sense_delay 1
muxstrobe_gate -PD1
sense_polarity 1

sense PD0

muxstrobe 0 UNASSIGNED
muxstrobe 1 UNASSIGNED
muxstrobe 2 UNASSIGNED
# ...
muxstrobe 94 UNASSIGNED
muxstrobe 95 UNASSIGNED
end
--- End code ---

Status update. I've got a proof of concept up and running. Thanks so much Soarer!

Next step map the key layout.
