We have created our own DCC controlled light switch, and it works fine when controlled from PC by sending an "ON" instruction over CAN.
The lights stay on as expected and we can turn them off again same way.
On the CS2 we see the actions happen, but we cant (or dont know) how to do it from CS2
we can define the module, and like with an "uncoupler rail" we can keep the lights on while holding the button.
the time-out setting cant be lower than 100 ms, and should be 0 for permanent use (as used from PC).
hope someone alredy used this, so all help is welcome.

Tks, Walter

Thanks for your reply Peter,


The program on PC, there I use a single button to act as ON/OFF for the lights, its not organized as the standard keyboard RED/GREEN combination (16 points on a keyboard) but 4 rows of 8 buttons giving up to 32 lights to command per keyboard.


With the DLC=6, CS2 automatically sends a byte 5 OFF after timeout (after button release)
So I do use the DLC=8 command CAN-ID 0x16 to switch ON/OFF the light decoder outputs from PC as follows

Byte 0..3.= 0, 0, 0x38, 163 ... DCC basic Button address for pair/impair
Byte 4....= 0 or 1 ............ for Pair/Impair button
Byte 5....= 0 or 1 ............ for OFF/ON
Byte 6,7..= 0, 0 .............. for permanent

I did build the custom light decoder on these specs using AtTiny 2313, and this works perfect.

So far we have not found how to set up a single (light) button on CS2 that can provide us this DCC ON/OFF function, as I don't use individual activate/deactivate, perhaps that's why we will not be able to test with CS2 direct unless the button is hold.

If there is a way to set up a single ON/OFF button on CS2, I still can change software for the light decoder accordingly.

Hope this shines some light on what we are looking for

Walter
