Since you are utilizing the Arduino Due you can safety interface directly to the EVE2 TFT Modules without a logic level converter.

Please note that the NHD-FT81x-SHIELD features a logic level converter for the classic Arduinos (UNO/MEGA/Diecimila). If you utilize the shield this will be redundant since the Due's logic is already 3.3V.

The EVE2 example code on our Github page was originally written for the classic Arduinos (UNO/MEGA/Diecimila... etc). I believe the example Sketches use direct pin manipulation to make things faster. However the Due is a completely different architecture to the Uno, so direct pin manipulation is done differently. Modification to the example code maybe required in order for it to compile.

3.3V is ok to use for VDD on this display.

TFTs / Does NHD-FT81x-SHIELD support Arduino due ?
« Last post by mrupprath on February 13, 2018, 01:21:17 PM »
Does the  NHD-FT81x-SHIELD support the Arduino due, and do i have to make changes on the example code when using the icsp header for SPI ?

Thanks

Hello,
does NHD-FT81x-SHIELD support Arduino due,
do i have to make any changes to the examples library for the 7 inch displays from your github repository, when using the ICSP header for SPI ?

Thanks inadvance

hi Doug

did you ever find the missing pieces of the code for SSD1322 for  PIC microcontroller
I am having the same issues with Shift and Ascii_1 not defined I am interfacing with a PIC32
if you did please share
thanks

OLEDs / NHD-0420CW-A*3 VDD Voltage level
« Last post by JBDynamics on February 13, 2018, 10:23:28 AM »
I am integrating this character OLED into a custom automotive gauge board. I need to know if VDD has to be exactly 2.8V or if the 3.3V I/O and power supply from an MCU/MPU like a Teensy 3.5 will work as well? If not would it be better to translate to 5V? I already have 3.3V->5V translation in the schematic to begin with so that would be easiest to implement. If it makes a difference, I am using the SPI interface.

OLEDs / NHD-2.23-12832UCB3-40956 display in SPI Bus
« Last post by BalajiNP on February 12, 2018, 07:37:06 AM »
Hi,
Trying this display in spi bus and after the initialization, display screen is black, i.e. nothing happen.

How to validate that the SPI bus transfer is proper? Any single command, the device will react in some form.

Do you have any test cmd in this display, so that we can confirm that device receives the SPI cmd proper and operate for this cmd.
This will helpful for initial bring ups.

Please help.

-Thanks.

Evaluation Tools / Re: NHD-4.3CTP-SHIELD-V - Examples still won't compile
« Last post by peterfarrow on February 12, 2018, 05:37:24 AM »
Hi Paul,

I am running Arduino IDE 2.1.0.5, the latest version, it doesn't compile.

I won't roll back to the 1.8 version since 2.1.0.5 is the latest repo provided version by apt-get and uninstalling this and installing from source is bad practice.

I have requested an RMA from Mouser.co.uk (my supplier) but they are being awkward.

All told a bad experience so far, but on the plus side our Nextion prototypes are working very well indeed!

Pete.

OLEDs / NHD-2.23-12832UCB3-40956 display & SPI Bus -- Initialization Sequence
« Last post by BalajiNP on February 12, 2018, 01:43:34 AM »
Hi,

This OLED display is connected in SPI mode. Need the initialization sequence for this SPI bus connections. Please provide this.

In I2C bus, this display is working fine. Can I use the same initialization sequence??

Please confirm.

-Thanks.
