UNO with 7 Pin LCD

I recently received an LCD that I ordered, but it was not quite what I was expecting. It has 7 pins and I'm not quite sure how to deal with this. Details can be found at I am wondering if there is any way to interface this LCD with an UNO R3 and if there is, how I would go about doing that.


I used to have a Chinese friend who was well versed in technical stuff and could translate datasheets like that for me. Unfortunately they decided not to renew her Visa and she's back in China now.

Your link shows HT1621 controller. The photos show clearly marked pins.

It would obviously help if you had a Chinese friend but it looks as if it is 5V tolerant.
All the same, I would try it with 3.3V logic first.

Google for an existing HT1621 library.
If you need help writing a new library for yourself, just ask.
