Along with my z80 development board I found a 16166 16*1 display.

I have found datasheets for the electronics, it have 8 data (but can be run in 4 bit also) and 3 control, but I have failed to find any actual programming manual.

Can anybody help?

It is probably this display: MDL-16166-SS-LV with HD44780 compatible controller.

  • \$\begingroup\$ Oh well, there is a library for this: arduino.cc/en/Tutorial/LiquidCrystalDisplay I can get away with only 6 pins. \$\endgroup\$ – Lenne Jan 2 at 20:17
