CDL with keypad

[TF_DOHC]

I have a CDL and have just acquired a 15button keypad. A PDM is in my future plans but for now I would like to use the keypad with the CDL. I have translated the keypad setup for the C12* dash back to the CDL but can’t get the keypad to respond to the dash. Any help would be appreciated

Hi,

Please see attached for a working example. There are some items that need to be transmitted for the keypad to wake up, along with the brightness settings.

The LED's are controlled with the bit combine function, so I have added the first 4 buttons in to light the green LED on key press.

Thanks Nathan, I had got a start from Scott @ Motec but that helps me understand the led's now!!

Any Ideas how to eg, push Button 1 once to activate channel , push button 1 again deactivate channel ??

Hello,

Below is an example of how you can create a latching function in your CDL3 using the keypad buttons.

I have created an Activate - Deactivate user condition with the Output Channel set as a GP Off / On.

The activate condition is Keypad Button X = 1 and GP Off / On = 0 for 0.2s

The deactivate condition is Keypad Button X = 1 and GP Off / On = 1 for 0.2s

The output channel will switch from 0 to 1 or vice versa depending on the value of the output channel.

The GP Off / On channel must have been either 0 or 1 for 0.2 seconds before the condition will accept another button press, this adds a debouce to ensure the deactivate condition isn't immediately triggered after the activate condition becomes true.
