Hello,

I can't find the wiring diagram for the NHD-0420CW (with I²C) with the NHD demoboard.

Where can I find it?

Thanks for your help!

  Hi Raphae1,
  
  Unfortunately, the NHDev board does not support an I2C interface connection to test this display.  However, the NHDev board does support a parallel mode connection to test this display. 
  
  Best Regards,
