//u8g.setHardwareBackup(u8g_backup_avr_spi);
if ( u8g.getMode() == U8G_MODE_GRAY2BIT ) {
u8g.setColorIndex(3);
}
u8g.setFont(u8g_font_unifont);
//u8g.setFont(u8g_font_osb21);
}

void loop(void) {
// picture loop
u8g.firstPage();
do {
//draw();
drawanalog();
} while( u8g.nextPage() );

// rebuild the picture after some delay
delay(50);

}

Here is the quick and dirty code i hacked together, even with the 50ms delay it is not usable.

going to try and get it working on the hardware spi..
