TFTs / Re: Is there a Visual Design tool for Arduino?

Which 4.3" Display did you order?

It seems that you will still need an external controller, i was curious to see if you received the Arduino Shield or just the display without a controller.

Evaluation Tools / Re: FTDI Eve screen editor

Were you not able to use the tool or did you have another problem?

This would be our first time working with the eve, and any information we can get to help improve the displays would help as well.

Hello Padmanthan,

This display does not support an I2C interface, you would need to use SPI or Parallel.
If you are looking to use I2C i would recommend our Slim OLED displays.

I appologize for the wait,

I will see if I can pull up your email and send you the copy of the model.

THis is most likely due to the timing.
This display uses a controller similar to our Character LCDs however it requires a longer wait between commands / data writes.

We have seen random shifting or characters appear when you write to the display too fast.

Unfortunately we do not have a library / driver for this display, however if you are able to modify the library you are currently using to add some delays. You should be able to use the display without any issues.

Character LCDs / Re: NHD-0216K1Z-FL-YBW grounding pad
« on: December 12, 2016, 08:13:09 AM »
Hello, Here's the reply I gave:

As the display is without having those jumpers populated pin 1 on the connectors is not linked to the mounting holes.
You wouldn’t need to cut the trace so long as the JFL remains unpopulated.

The first pad is connected to the mounting hole located on the bottom left of the picture below.
The second pad (K3) is connected to the plate for the Bezel Tabs.
The final pad (JF) is connected to the ground of the display. (Pin 1 on both CON and CON1)

OLEDs / Re: NDH-0220CW: cursor not visible with text
« on: December 07, 2016, 08:04:04 AM »
Hello,

Good to see you've got it.
Unfortunately it is not possible to disable the cursor moving either left or right after printing a character. You would need to manually set the address to the desired location and rewrite the character printed where you need it.

This controller will allow you to increment or decrement the address counter after printing a character.

Hi,

The pin layout will follow the first option you listed.

The cursor should still be able to show up.
Would you be able to tell me what settings you have for the Display On/Off register?

What is the current limit for your backlight supply?

For the backlight you would not need to apply the Display Enable signal. Also could you give me a date code for the display you are currently using?

Graphic LCDs / Re: NHD-C12864WC-FSW-FBW-3V3-M random pixels at init
« on: November 28, 2016, 02:04:11 PM »
This is most likely due to the high contrast. I would recommend using a lower setting for the electronic volume.
This will determine the pixel clarity.

It seems that your contrast might be set a bit high.

The random pixels can result from any mix of information that could be stored in the RAM for the display controller.
Have you tried to clear the screen after initializing it?

TFTs / Re: NHD-2.4-240320CF-CTXI#-F spec on VDDIO
« on: November 22, 2016, 12:18:14 PM »
Hello,

We often recommend tying the VDDIO to the VDD pin.
The 3.3V is still within the safe operating voltage for the Controller IC.

According to the Datasheet (Page 131), the VDDIO needs to be powered down before the VDD.
Datasheet: http://www.newhavendisplay.com/app_notes/ST7789S.pdf

Because of these we have not tried to test power drain while VDD is not applied.

Hi,

For 3D model requests, can you please email nhtech@newhavendisplay.com.
