ST9720 in serial mode - how to wire?

dc42: Another solution for the LCD might be a ST7920-based 128x64 graphic LCD, which needs only 2 pins to drive it.

I'm resurrecting an old thread.... What's the correct wiring for the ST9720 based displays in serial mode? What pins do I have to connect?

A quick Google search turned up

In this case (only using Clock and MOSI) you can use shiftOut() in place of the SPI hardware.

Thanks. I saw that earlier but I missed the part in the source where he has the pins.

Is there a library that can use these? glcd? dfrobot has an arduino library for serial, but I guess I’m looking for something more “official” - and also better documented.




Thank you!
