T35 Display backlight control


#1

Is it possible to power-off the backlight of the T35 display in code???


#2

Should but I am not sure if this was added to the driver. Will check tomorrow


#3

OK, thanks for the quick reply


#4

Was this added to the driver?


#5

Not yet but the source codes are codeplex if you like to jump in :slight_smile:


#6

Sorry, what do you mean by codeplex. I am a newbie :slight_smile:

#8

If I read the standard right Pin 9 on Socket G should control the backlight for the LCD; can you tell me is the a PWM or GPIO pin?

I’ll update the source to give backlight control. :slight_smile:


#9

I think Steven already has the code?


#10

@ Steven; I’m looking at this code in codeplex and I see nothing about the backlight control on the project. I’d be happy to add it in, just wondering if the pin is GPIO or PWM?


#11

You can if you’d like. The pin is GPIO.


#12

So only ON/OFF then huh? Well it’s better than nothing. :wink:


#13

You can do PWM I think but this is not required in gadgeteer specs. I am not sure how would you dynamically detect if the pin is PWM or not!


#14

I actually do checks on my module for interruptable or not since Hydra supports full interrupts even though it’s not required. :wink:
