Evaluation Tools / Re: NHD-FT81x-SHIELD
« on: January 30, 2018, 08:30:29 AM »
Morning Carl,

I've only utilized the EVE Screen Editor V2.3.4 when designing with the 4.3" Arduino Shields which utilize the FT800 & FT801 ICs.

Unfortunately, FTDI has not added Arduino support to the EVE2 ICs (FT812, FT813) at this time. The only option I see in the drop down menu is for Bridgetekís Development Modules.

As a workaround you can mock up your GUI and port the Coprocessor commands to your Arduino project.

Hey Jesse,

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

Hey Carl!

The select example projects on our GitHub page are Arduino Sketches. You don't need to import it as a traditional Arduino Library. 

Regarding the EVE Screen Editor, I don't believe there is an option at this time to output Arduino code for the FT813 IC.  However, you should be able to make it output C code and modify it to run on the Arduino IDE.

Hope this helps!

Brilliant, thank you for sharing Carl! Can't wait to see version 2  ;)

Glad to hear you got your display up and running!

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

TFTs / Re: NHD-4.3RTP-SHIELD-N Pinout
« on: October 17, 2017, 08:31:08 AM »

The 'Pin Description' is listed in the NHD-4.3RTP-SHIELD-N datasheet ( see page 8 ).

Hope this helps  ;)

OLEDs / Re: SEPS525 is only 3.3V tolerant?
« on: August 31, 2017, 07:59:02 AM »

The NHD-1.69-160128UGC3 is 3.3V tolerant.

The NHD-1.69-160128ASC3 design includes built-in logic level shifting so you can use it with 3-5VDC power and logic levels  8)

Hope this helps!

Evaluation Tools / Re: NHD-TFT40 PWM pin
« on: August 29, 2017, 10:53:58 AM »

The NHD-TFT40 is designed to work with our 24-bit Parallel RGB Interface TFT displays that require the RGB pixel data to be clocked in continuously.

The backlight driver defaults to 40mA and can boost up to ~24VDC for up to 7-LED strings. Check your display datasheet for the string configuration.

Per your request I pulled the NHD-TFT40 from stock and connected it to the NHD-4.3-480272EF-ATXL#.

Please see the attached images, note that when the PWM signal is tied to GND the backlight turns off as expected.

Morning Carl,

Very strange, I know this might sound odd but can you please tell me what brand micro SD card you are utilizing?

Regarding the MEGA you can always bypass the LDO by powering the board with a USB wall charger.

At this time I'm not aware of any Energy Efficient Arduino MEGA clones.

Hey Carl,

I went ahead and pulled the NHD-4.3CTP-SHIELD-N from stock and powered it with an Arduino UNO clone (NERO) from the lab.

All three sketches have been tested and verified to run properly on the Arduino UNO (see picture attached)

Can you please clarify how you are powering the Arduino UNO clone?

Have you been successful running the "Basics" Arduino examples (

TFTs / Re: NHD-10.1-1024600AF-LSXV-CTP #SUPPORT
« on: August 10, 2017, 03:45:07 PM »

Please note that the NHD-10.1-1024600AF-LSXV#-CTP does not utilize a "controller board".

The TFT display uses a LVDS interface. LVDS is quite straight forward, and is just parallel data serialised 7:1. The RGB, DE, and syncs go in defined places.

Does your source output LVDS?


OLEDs / Re: Controller questionfrom a newbie
« on: August 10, 2017, 03:28:14 PM »
Welcome to the forum  8)

To keep things simple the "Controller" or driver chip manages the display.

Take as an example the NHD-1.69-160128ASC3:

This display utilizes the SEPS525 controller and you will communicate via 4-wire SPI to your MCU.

The controller or driver chip is bonded onto the displays cable via a COF (Chip-On-Film) process.

Hope this helps!
