Does anyone have suggestions/experience with using an 8-bit serial-in, parallel-out shift register like the 74HC164 to drive a LCD panel? I have been using a LCD module in 4bit mode, and want to try something a little cheaper.
How about hints for using 2 of these in tandem for a 2 digit LCD? 3 in tandem for 3 digit?...
It would be useful to know how to use a SPI port on a tiny AVR w/ the shift register for driving a simple LCD display.
thanks to any an all replies
