162F not initialising with Arduino mega

Hello

I having trouble with a 162F display whereby I cannot get it to display anything. I have adjusted the bias pot for the display across the whole range of voltages - no joy.  
 

The Arduino code, liberary and circuit work fine with another make of 16 x 2 display.

 

so if the Arduino code is good

the circuit is good

the bias has been adjusted over whole range

the liberary may be where I am falling down if the initialisation timings / settings are not quite rightful this display.

any help from anyone much appreciated beginning to lose sleep on this one

Hi,

We are not familiar with the Ardunio library.

The 162F uses one of the 2 LCD drivers avaialbe in our knowledge center (and as called out in the datasheet).

I applogize that I don't have example code for you. These module have been around forever... maybe the Ardunio library uses a different controller?

Thanks,

I am away from my workbench for the next few weeks , I will shoot a video when I get back in an attempt to prove the wiring is correct 

 

Merry Xmas
