Notes:
The font selection pins should generate the 8x8 font.
For the MGLS240128TZ only FS1 is available on pin 18.
FS1 must be low to generate the 8x8 font.

Display: http://www.tme.eu/en/details/rx240128a-ghw/lcd-graphic-displays/raystar-optronics/
Connection: HW / SW SPI.
To get this display working, You need some extra capacitors:
connect 4.7uF caps between:
PIN1 & PIN2 VB1 +-
PIN3 & PIN4 VB0 -+
connect 0.1uF caps between:
VLCD and VSS
VBIAS and VSS
You can find some schematics with a 10M resistor parallellized with the VLCD capacitor.
Select 4-bit SPI mode.
Connect D7 (PIN9) To VDD (+3.3V)
Connect D1, D2, D4, D5, D6 to GND (PINS 10,11,12,14,15)
Connect WR0, WR1, BM0, BM1 to GND (PINS 17,18,22,23)
D0: (PIN16) AVR's SCK pin (HW SPI)
D3: (PIN13) AVR's MOSI pin (HW SPI)
CD: (PIN19) used as A0 in the library
CS: (PIN21) Connect to the defined CS pin, and You can re-use the HW SPI in different routines.
RST: (PIN20) optional reset, can be defined in the function, resets on initialization.
Adjust contrast if necessary. Default: 0x072.
