The HT1632 has now been integrated into U8glib. I have added the new constructor to HelloWorld and GraphicsTest examples (other examples will be updated for the final v1.13 release)
U8GLIB_HT1632_24X16 u8g(3, 2, 4); // WR = 3, DATA = 2, CS = 4
You should be able to change the Arduino pin numbers to whatever is required.
I have attached a prerelease with the new constructor call. Please let me know if this constructor call works correctly.
The virtual screen feature (combination of four screens to one huge screen) should also be possible now.
