[Cignale]

In this chamaleon forum thread there are the "codes" explained; maybe
this can help ?

That might do it. I will have to see how it works. I was thinking the mouse was different than the controller but when the controller has mouse mode activated it might act as a mouse.   I am thinking of using a Propeller CPU and SPIN to write a driver for PS2 to 40 KHZ CDTV mouse and joystick IR brick for use with a CDTV and Chameleon.  I hope to get it going this coming year...

This is how the remote looks like:

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).
