EA OLED Display w/ SPI W162-X9LG

Using Arduino Displays
1

Hello,

I'm currently struggling with the EA OLED display 16x2.

I have changed the solder bridges on the back according to the documentation --> http://www.lcd-module.de/fileadmin/pdf/doma/oled.pdf and connected the display properly to the arduino SPI ports

However, I don't seem to get any successful communication with the display at all.

Has anybody managed to control the display (which chip is used? is it the WS0010?) properly with the built-in SPI functions?

Thanks for your support in advance.

You will need a compatible library to use the SPI interface. It will probably be easier to use this guide and use the 4 bit interface.

The controller is compatible with the HD44780 instruction set but is a different device.

Thanks for your support @bodmer.
I didn't get it to work properly with built-in SPI.h as well as with manual SPI bit banging.
So --> I went back to 8-bit control (but via an 8 bit shift register) to save ATmega ports.
