Just purchased a Seeed 16*2 lcd display robot shop number RB-See-86. I can only get the top line to work. I have used the arduino example scroll and nothing displays. I have changed the code lcd.begin (16,2); to lcd.begin(8,2); as given in the tutorial on the item description page. However I can only get the first line to work by using the following code lcd.begin(16,1);. Is this display only a single line display? What am I doing wrong? All other tutorials indicate that this display should be a 16 character, 2 line display. Do I have a bad display? Thank you for any help.
Hi lhompoth,
You might want to look at the tutorial for this LCD on Arduino website:
Make sure your wiring is exactly the same and use the code provided as sample.
Hi Eric, I have gone over the example many times and this display will not operate correctly. I must have a bad display. The tutorial is very clear and my wiring is exactly as shown on the tutorial. I will get another display and carry on.
Thank you for the reply.
We suggest that you submit a ticket about the issue to our Support Center.
Make sure you send it to “Exchanges / Returns” and you can add a link you the forum post here.
If the item is warranty we will replace it.
All the best,
Hi Eric and thanks again for the information. I was under the impression that since I have soldered on this display that I can not
return it or get warranty. I will followup with a ticket later.
Regards
No problem, we will handle it.
