There are no library for HD44780-compatible SPI display. It can be written, but needs display in hand for testing.
You can connect this LCD with 4-bit connection:

Code:
 $regfile = "m168pdef.dat"
 $crystal = 16000000

 Config Lcdpin = Pin , E = PORTC.2 , Rs = PORTC.3, Db4 = PORTC.4 , Db5 = PORTC.5 , Db6 = PORTC.6 , Db7 = PORTC.7 ,
 Config Lcd = 16 * 1
 Initlcd
 Cursor Off

 Do
   Cls
   Lcd "TEST LCD"
   Wait 2
 Loop

are you using 3.3V For VCC ?
IF you use 5.0 you can buy another display....

No reaction, nothing works,
I connected to 5v and 3.3v and nothing.
There must be some other initiation procedure
this display.
