LCM4002A-1 LCD's

Hi All,

 

I purchased these 2 LCD display’s but with the ‘universal’ driver in the MB-SEQv4 the output is garbled.

After some more searching, it looks like these displays are ‘4-bit’. 

Can I choose a compatible driver and compile after that? Which one would suffice from the list:

clcd\_parallel  holtek16514  ipad  juce  macos  pcd8544  ssd1322  st7637  t6963\_h  t6963\_v  uc1610  universal

 

The specs I could find for my display: Product Introduction: Model : LCM4002A-Ver 1 Product Type: Character LCD Module Display Format: 40\*02 Characters Interface: 6800 4-bit Parallel Font: English/Japanese Control chip:SPLC780D Outline Dimension: 182.00(W)x33.50(H)x14.50(T)mm Visual Area: 163.00×26.60mm Active Area: 147.50×11.50mm Viewing Direction: 6:00 IC Package: COB Power Supply(Typ): 5.0V

 

my problem was a bad driver chip on the bhp_seq interface board…
