I got hold of a H2571 Liquid Crystal display and I am looking for the following information: 1. What is the pin configuration? 2. What type is it e.g. 2x40 characters? 3. Which is pin 1 on the connector? 4. Can it be used with 4 Data or 8 Data lines? 5. Does it have back lightning? It uses the HD44780 controller chip. I will appreciate any info on this module. Tks.
