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

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?

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.

Evaluation Tools / Re: FTDI Eve screen editor

Hi Joe,

You should be able to use the Screen Editor with the Shield.
You would need to select the FT801 for the Device. And under the Export drop down, select the VM801B43 option.

OLEDs / Re: Question about 256x64 sample code
« on: November 16, 2016, 03:13:30 PM »
Some of these commands are required for our NHDev Development Board code.

I do have example Arduino code for this display, could you please email me at sbaxi@newhavendisplay.com for the examples.

OLEDs / Re: Flickering NHD-0220CW-AY3
« on: November 16, 2016, 03:10:50 PM »
The flickering can be caused by a lack of current being supplied to the voltage boosting circuit.

Would it be possible to record a video of the flickering that occurs?

Hi,

Would you be able to tell me what the date code on the display is, or if possible to take a picture of the back of the display?

We have made a change which has larger thru-holes for our OLED displays.
However before this we traditionally used the TE 9-146282-0-20 single row pin headers for the older models.

Hi,

Do you have a limit as to how much current your VDD line could supply?
