Would it be possible to share the segments of code that write the pixels and clear the display.

The clear and fill could possibly be sped up by speeding up how fast you write to the display.

The display has a 400 ns Serial clock period, and theoretically you could fill the whole display in about 3ms.
If you are calling for delays within the write command this could greatly reduce the time it takes clear or fill the screen.

Unfortunately we do not have any displays with a UART interface.
We do have Serial Displays that use a RS232 Interface, but unfortunately the smallest display has 2 lines and 16 characters.

For your size requirement i would recommend taking a look at our new OLED Glass.

This is a 2x16 OLED display that has an outside diameter of 41.4 x 19.9 mm.

It also has a double height feature that will allow you to use it as a 1x16 display.

This display has the following interface options.
- 8/4 Bit Parallel (6800 or 8080)
- IC


There is a command to turn all points on.

Using command #10, 0xA5 will turn all points of the display ON.
You can reverse this by using 0xA4 (Normal display).

Hi Richard,

Unfortunately standard IC libraries will not work with this display.

You can use the following example code to help you get started:

I have not heard of this issue.

Can you confirm the rest of the RS-232 settings?
- 1stop bit
- no parity
- no hand-shaking

Also would it be possible to share the list of commands you are sending to the display?

3.3V will be fine in Low Voltage Mode

These are going to be totally different controllers.

The ILI9341 is a controller made for TFT displays (Full Color LCD). Where the SSD1325 is made for monochrome OLED displays.

If it helps I recommend looking at U8Glib, which is a graphics library made for various OLED controllers.

You can find their site here:

Is it possible to post a sample of your code that writes the functions?

It seems that the command its receiving is the clear display command.
Command 0x0C should not affect the memory or address at all.

I do have a sample code that will work for an Arduino MEGA, but unfortunately not for the due.
The Arduino Mega does have its voltage regulator switched out to provide 3.3V logic.

If you would like that code please email me at

The controller on this display is compatible with the ST7066U. The commands and writes can take up to 600s, so you would have to either check the busy flag or use delays between commands.

Unfortunately we do not have any oled displays that would match the 182x33.5 mm OD.

I would recommend taking a look at our 4x20 Slim OLED displays, Their outside dimension is 92 x 31.5.
Other features include:
- 3V / 5V Operation
- 8/4-Bit Parallel, SPI, or IC interface
-10,000:1 Contrast Ratio.
-Available Colors: Blue, Green, Red or Yellow.



Firmware version 2.1 does have added support for the NHD-2.4-240320CF displays. You can download the files here NHDev Downloads

TFTs / Re: No Backlighting

You will not be able to see anything on the display without the backlight. For TFT displays the backlight is a requirement.

The NHD-4.3-480272MF-34 controller board does have a voltage booster circuit, but the original circuit was designed to operate with the NHD-4.3-480272EF-ATXL# (Standard brightness display)

There is an option to power the backlight using your current board, but it will require some modification to the controller board.

1. You will need to replace the LED Driver on the controller board. This will be labeled U2, it is located right above the 40 pos FFC Connector for the display.
    I recommend using a FAN5333BSX

2. You will need to swap the resistor on R45 with another resistor that is roughly ~7.8 Ω.

The LED driver will be able to produce the required voltage after these changes are made with a 3.3V input.

The parts i mentioned above are shown in the attached image.

Hi peter,

Two options you have to connect the -34 controller board to your arduino.

1. You can use the NHD-FFC36 with a 34 Pos 0.5 mm Pitch FFC such as THIS
Because the PCB has a 36 position Molex connector, you would need to off set to one side an leave 2 pins un connected.

2. You could get the following:
- Solder a 34 position FFC connector onto the 0.5mm pitch bar. Example of 34 pos connector OMRON XF2M-3515-1A
You will still need the FFC Cable from above.

With both of the parts above you will need 2x 2x9 Standard Pin Header
