Title: 2X20 small display (up to 70x20mm) with i2c interface
Post by: igorak77 on September 27, 2016, 01:55:42 PM
Hello,
I am looking for 2x16 or  2x20 character display that should be connected to Intel Atom processor.
The problem that I need very small display (up to 70mm length) and with  .
I found that NHD-0220FZ-FSW-GBW-P-3.3 meet these requirements but it`s support only parallel interface  (Intel processor don`t have this one).
The questions is:
1. Could you please check and suggest display with these requirements?
2. Could I stay with option of NHD-0220FZ-FSW-GBW-P-3.3 and  connect i2c to parallel bus (8 bit) controller 8 bit PCA9564 ? In this way the i2c side will be connected  to Intel and Parallel bus side to display.
Thanks

Hello,

Another option i would recommend would be our Chip-on-Glass displays specifically the NHD-C0216CiZ-FSW-FBW-3V3 (http://www.newhavendisplay.com/nhdc0216cizfswfbw3v3-p-2930.html).
However this display does have a 3V interface ans will require 2 external capacitors and 2 pull up resistors.

Like you mentioned above with the NXP PCA9564, you could use a LCD Backpack that would allow you to convert from the I2C to the 8-Bit Parallel.
