CDTV mouse protocoll?

[freqmax]

What protocol does the CDTV mouse really use?, it seems to be a real oddball..

This is what I could find out:

Mouse (4 pin mini-DIN):

cdtv.org.uk: Commodore CDTV Expansion Ports Explained from link at abime.net
Pin Signal
 1 GND
 2 GND
 3 PRDT (Mouse Data?)
 4 +5V

One use logic analyzer and some brains, it usually gives the answer.

But one need equipment to rig it. And then to export the data. Any takers?

Seems even the "The Amiga Developer CD" assumes the mouse is a 9-pin device 8 Interface Hardware / Controller Port Interface

CDTV is an oddball

The "CDTV - CD-1253 - Mouse - Manual-DE.rar" only tells you where to plug in the mouse in essence..

Sounds plausible. Guess only soldering & programming remains then

Nothing like "move mouse" keys on the remote control ?
Otherwise.. send random bits until you get some response.

This is how the remote looks like:

Vesalia.de - CDTV Remote Control


And this seems to be the protocol then

YahooGroups: chameleon_64 · Turbo Chameleon 64: CDTV Infrared Remote Codes
"This is what I think, as the serial codes from IR, Keyboard and Mouse are all handled by the same MCU in the CDTV. My guess is the codes are all the same "

"Ofcourse I know the codes as I made the receiver code on the Chameleon. The carrier is indeed 40 Khz and the remote uses something that looks like morse-code. The codes are 12 bits long but are send twice with the second copy all bits are flipped. This is verification that the code is correctly received.

Code starts with 9 ms transmission (at 40Khz) then a pauze of 4.5. Followed by pulse (400 us) + either short or long pause, then another pulse + either short or long pause etc 24 times. Then one pulse extra at the end.

Pulses are about 400 us long (0.4 ms). Short pauses are 0.4 ms as well. Long pauses are 1.200 ms (1200 us).

When key is held it sends repeat codes every 60 milliseconds. 9 ms pulse followed by 2.1 ms pauze and then the 0.4 ms end pulse.

The codes are as follows (remember to invert long and short and send then again before sending the end bit of 0.4 ms).
