In this video we are taking a closer look at the LCD module and how to program it. Datasheets links: 1. www.futurlec.c... 2. www.openhacks.... Source code: drive.google.c...
These LCD are fun to learn on but not good if you are designing a product that requires many of the IO pins. At one time I was using a shift register between the AVR and the LCD to limit the number of IO pins needed. Ultimately I moved to a serial version of this display. Uses just the TX pin of the AVR at 9600 baud. You can even control contrast and brightness via the RS232 connection. And with the 328PB now having two USARTs you have a spare if you need it. :-)
