The datasheet for the HD44780 chip includes the timing diagrams and instruction set for operating this module. It can be downloaded at

Works OK but you have to speak SLOWLY...

Reviewer: from Camarillo, CA

So I tried using these with a Microchip PIC16F1933 (like them because with a 28 pin skinny DIP pkg I've got all the PCB tools to lay out and build boards, it has a real data EE memory, lots of PWMs so I can feed direct to logic level N-ch pwr MOSFETS etc.). Wrote a little control pgm and I set aside 11 pins because I wanted to use the full "busy flag" interface and talk to the display quickly. But by the time I got this thing to actually display all the characters I was feeding it I had to slow the processor clock down all the way from 32 MHz to 1 MHz while I was talking to the display! That meant I would have to change all the other "clock chains" to have them SPEED UP by a corresponding amount during this time...unfortunately that meant cutting out more downcounters from those chains than I actually had in them! So if you're working on any projects designed after about 1982 you'll probably want a display with a LITTLE faster controller, but like I said it DOES work as specified...!
