Hi,

I have lpc4088 based device. I would like to make LCD's backlight off.
I couldn't find Control Register and those bit to do that.
Will you show me the way to do that?

Hi MC,
Thanks for your advice.
I use IAR evaluation board, and can I control backlight without PCA9532?
If I can, will you show me how to control backlight with Register and those bit?

Hi Koichi,
LPC4088 will provide you control signals (HSYNC,VSYNC,LCDEN etc) and LCD panel data(RGB signal). You will need LED driver to control the back light. You can use i2c based PCA9532 with addition circuit to control back light.
