Hi,
A FIXME in picolcd.c says: "Is 0x00 or 0xFF correct to turn backlight off?"

On my picolcd 20x4, it requires 0x00. According to this post,
http://www.linuxconsulting.ro/picoLCD/docs/picolcd-256x64-protocol-rev3.txt,
this is also the case for picolcd 256x64.

I've attached a patch which corrects this.

Cheers,
Steve
