New ContributorAria 10 LCD I2C address
Hi, We are trying to figure out a way to send some display characters to the LCD and cannot find the I2C address in the manual. Could someone tell us how to find it? Thanks!
Hi Yong Chi,
From my findings,
The LCD char display is NHD-0216K3Z-NSW-BBW-V3
Link to the datasheet:
https://www.newhavendisplay.com/specs/NHD-0216K3Z-NSW-BBW-V3.pdf
The slave address is 0x50 by default. It can be changed to different address with CMD 0x62, refer page 7 from the datasheet.
Thanks.

Regular ContributorHi Yong Chi,
To clarify further,
The LCD can on after the display on cmd is sent right?
If LCD display on is working, compare the data signal with LCD display off considering the acknowledge bit for address and cmd. From here maybe can tell the problem.
Thanks.
