LCD+Backpack backlight questions

Post by peluke »

I'm using the HD44780 with the i2c backpack, all is working well and the display is nice and bright. crazy so.

would it be possible to remove the pin 15 from the lcd+backpack setup and just connect it to +5v or a pwm controlled output to give me some degree of control over it?

thanks

I believe this should be fine as pin 15 on standard HD44780's is for nothing but the backlight. I always pwm mine so they can "sleep". Hope this helps.
