New Product Releases / Introducing our New EVE2 TFT Modules

New EVE2 TFT Modules

The extremely powerful EVE2 generation of integrated circuits (ICs) are now available with new TFT display modules from Newhaven Display International. Newhaven Display has teamed up with FTDI/Bridgetek to create a high quality full color display product backed by the feature-rich FTDI EVE2 Graphic Engine. The product line is made up of twenty different modules ranging in size from 3.5” diagonal to 7.0” diagonal. They also come with options for resistive or capacitive touch panels, as well as Newhaven Display’s Standard, Premium, and Sunlight-Readable display variants. For the first time ever, these new products allow you to connect to a Newhaven Display TFT via SPI interface. The modules are packaged with fully integrated capability for video, audio, and touch interactivity.

With Newhaven Display’s EVE2 TFT Modules, you will find two standard 20-pin connection options on every board – a 1.0mm FFC and a 2x10 2.54mm IDC connection. Both of these connector options will bring you the full power of the integrated EVE2 IC, without ever sacrificing display brightness. Typical TFT Modules will compromise the backlight brightness to accommodate the featured IC; however with Newhaven Display's EVE2 Modules, the full potential of the display's backlight luminance is available and can be adjusted as needed with the Pulse-Width Modulation controls available on each model.

Like never before, communication with these Newhaven Display EVE2 TFT Modules is done via serial (SPI or QSPI) interface. This offers you the ability to keep your microcontroller costs low while still providing a rich list of features thanks to the FTDI/Bridgetek Graphic Engine. SPI interfacing expends less pins (I/O) and the IC source is the latest and greatest, so you can design these products into your project without fear of near obsolescence.

Hey Swulf,

Thanks for sharing your demo code, it will definitely help others  8)


Here is a complete demo for the Newhaven NHD-0216K3Z-FS(RGB)-FBW-V3 display module that runs on an ATMEL ATtiny 2313A 8-bit microcontroller. It's written in C and should be really easy to follow. You will find the complete set of Solution files for use with the ATMEL Studio 7 development environment on GitHub at the following link.

Feel free to let me know if you have any questions about it, or if I can help you get it going on your own hardware.

Glad to hear you got your display up and running!

Thanks for sharing your solution, it will definitely help others  :D

Solved, the 2.2k poll-up was the root of the evil. Removed from the demo board and replaced by an external 10k, all is doing right!! Those 10k are pretty important...
OLEDs / NHD-0216MW-AB3: no voltage on IREF (pin 22)
« Last post by asfarley on December 06, 2017, 05:52:50 PM »
I'm working with an OLED module for a new product. Previously, we used the module NHD-0216MW-SB3 which doesn't include a contrast resistor setting. In our new layout, we use NHD-0216MW-AB3 which doesn't have the same peripheral circuitry as the NHD-0216MW-SB3 module. The display is being used in SPI mode.

The display isn't responding to commands. I believe the SPI commands are correct because they worked on the previous module; both devices use the US2066 internally and they're both running on low-voltage IO logic.

Measuring on IREF, there is no voltage. All the other pins on the OLED module look correct. Here's what I've measured on a multimeter:

1 (VSL) = 0.0
2 (VSS) = 0.0
3 (REGVDD) = 0.0
4 (VDD) = 3.15
5 (VDDIO) = 3.15
6 (BS0) = 0.0
7 (BS1) = 0.0
8 (BS2) = 0.0
9 (/CS) = 3.15
10 (/RES) = 3.15
11 (NC) = 0.0
12 (NC) = 0.0
13 (NC) = 0.0
14 (SCLK) = 3.15
15 (SDI) = 3.15
16 (SDO) = 0.0
17 (NC) = 0
18 (NC) = 0
19 (NC) = 0
20 (NC) = 0
21 (NC) = 0
22 (IREF) = 0
23 (VCOMH) = starts around .06V, slowly drops
24 (VCC) = 9.5

So - where is the IREF voltage (VCC - 4.5) generated? Is this indicative of any common problems?

Is the low/dropping voltage on VCOMH expected? I don't understand what "COM signal deselected voltage" means.
TFTs / Re: Help with NHD-5.0-800480TF-ATXL#-CTP

This would depend on how you are planing on communicating with the display.

Most CTPs have have built in Controllers have multiple drivers available; at times these are even provided by the manufacturer.
If you are going to be using an external controller, this can be quite a bit different. The external controller (SSD1963, EVE, ect...) should have some stock drivers that can be found online.

Saurabh_B, thanks for the reply! Can you provide any resources on how to develop driver files for displays? Perhaps you can even give me search terms for me to perform on my own? Any guidance would be very helpful.

Are you sending a delay between the commands or allowing the commands that were sent to execute?

Would it be possible to show a schematic of how you have the display connected?
Other than the shift register you also have certain control signals that need to be toggled to latch the data.
