Tearing my hair out - anyone got a Newhaven 20x4 OLED working?

-

i have searched every thread on forum, , followed every link can find online, , tried various 'solutions'. still unable newhaven 20x4 oled (nhd-0420dzw-ay5) working arduino.

it seems general concensus liquidcrystal.h library doesnt allow sufficient initiallisation time particular display. have looked @ others' customised libraries, tried serial wiring etc. nothing can find works. not competent enough @ .h , .cpp files , know needs changed.

does have working library, example sketch , wiring diagram put me out of misery?

did find this page ?

seems have quite clear instructions, addressing problem.
