Backlight control

Postby Donovan CR6 on Tue Oct 10, 2017 9:21 pm

What would be the best way to dim the back light to 60% when you turn the headlight on? Or how do i change on/off status to percentage? Did it before i used display creator, not so easy now

Thanks Don

What logger are you using to control your display?

Normally, I would use one of the inputs (AV or Dig) as the input to a table with the output being a display brightness percentage. How this is used varies depending on the dash you are using and how it's connected to the thing controlling it.

Hi David

If you have included the CAN the template "DM Transmit", that has the channel "D1 Backlight Brightness" that controls the backlighting. I'm pretty sure that works even for the internal display.

So you could make a table with the PDM Output Status as the input to provide the value for the "D1 Backlight Brightness". Another neat option is to use the Up/Down counters to control the backlight brighness with some button presses. You could feed this as another axis into your D1 Backlight Brightness table, so the backlighting can be set by the driver, but sill dimmed when the lights are on.
