CFAG12864B-WGH-V backlight?

[tr8it0r]

How do you connect up the backlight on a CFAG12864B-WGH-V? I have the A and K pins 19 and 20 respectively. K being ground but what do I give A? 5V straight? do I need a POT if so how would i connect it up?

Thanks,

Josh

The backlight on a CFAG12864B-WGH-V is an EL backlight, so +5v and Gnd supplied to A and K will not drive the backlight. You will need an EL inverter to do this.

You can order one using the link below:

CFAX Backlight

I bought the EL driver by crystalfontz, I can't make the backlight in my CFAX LCD to turn on. I connect the I pin to 5 volt, the G pin to ground, and the O pin to the BL_EN to my breakout board (I'm using the break out board sold in sparkfun.com, http://www.sparkfun.com/commerce/product_info.php?products_id=463). The LCD does not light up by doing this, so I tried connecting a resistor(68kΩ) and a capacitor(2.2nF) in parallel in between the O pin of the CFAIEL and the BL_EN pin, did not work either. Can you give instructions on how to connect the CFAIEL to my CFAX LCD. Thank you.
