KS0108 library SPI serial mode?

Using Arduino Displays
#1

Ciao a tutti, ho un vecchio display Winstar 22 pin 12864 REV.J WZ-1, ora funziona con la libreria u8glib-KS0108 in modo parallelo.
Ho bisogno di liberare un po di pin e usarlo in modo SPI seriale.
E' possibile? C'è una libreria per questo?
Grazie.

Hello everyone, I have an old 22-pin display Winstar 12864 REV.J WZ-1, now works with the library u8glib-KS0108 in parallel.
I need to free up some of the pin and use it SPI serial.
it's possible? There is a library for this?
Thank You. Sorry for google translate.

The display itself does not support SPI.

Oliver,
Have you ever looked at doing an i/o interface layer for the MCP23016 & MCP23017 that could sit on top of the existing LCD code?
That way users could wire up an i/o expander to parallel devices like the ks0108 and reduce the Arduino pin count.

I’ve got it in the plans for openGLCD just haven’t gotten around to it yet.

Hi Bill

Well, yes, I was thinking about such an expander. But at the moment I am too busy with other topics. In fact I do not plan to add such a feature to U8glib in the near future.
