Morning,

Sorry for the confusion, however I can assure you that the Supply Voltage (VDD) for NHD-0420DZW-AY5 is 3.0 (Min.) - 5.0 (Typ.) - 5.3 (Max.).

The prefix "5" in the part number represents the displays typical voltage.


Have a good one!  ;)

Morning,

To answer your question the Supply Voltage (VDD) for NHD-0420DZW-AY5 can be anywhere from 3.0 (Min.) - 5.0 (Typ.) - 5.3 (Max.).

This can be viewed on page 6 in the displays datasheet:

Hope this helps!

Hi Jim,

Sounds like a fun project!

The timing values listed above are perfectly acceptable, I would like to see your boot process if possible.

To see the actual boot process a RS232 cable like the TTL-232R-3V3 from FTDI is needed. Just plug it into the J1 connector and open a serial terminal of your choice.

Finally, post the terminal output on the forum so we can start debuging  8)

Hi Jesse!

Great question, when a display has a Hot-bar connector the flex needs to be soldered directly to the pcb. You will not be able to locate any standard FFC connectors to accommodate this.

There are a lot of benefits for using a direct flex-to-board connection. It saves vertical height, can be more reliable than fine pitch connectors and saves the cost of the connectors.

Morning Zafi,

I recommend using NHD-1.8-128160EF-CTXI#-FT:

http://www.newhavendisplay.com/nhd18128160efctxift-p-7133.html

Please note this particular display is Non-Stocked and requires a MOQ of 3000 pc.


The MOQ maybe an issue in your case, it might be worth taking a look at our 2.4" Resistive Touch TFT's with a standard FFC ZIF connector (In-Stock):

Hope this helps!

Hello!

The LCD connector on NHD-1.8-128160EF-CTXI# needs to be soldered directly to the pcb (via a Hot-bar machine).

If you are interested in a traditional FFC ZIF LCD connector I recommend using the following display:

NHD-1.8-128160EF-CTXI#-F
http://www.newhavendisplay.com/nhd18128160efctxif-p-7337.html

LCD Connector: 24pin 0.5mm FFC connector. Molex P/N: 52435-2471

Very nice, enjoy your new TFT!  ;)

Hello,

No code / initialization sequence is required to turn on the displays backlight. Simply applying 40mA @ 19.2V to pin 2 and Gnd to pin 1 will turn on the backlight  :)

Please verify the operation of Pins 1 & 2 with a DMM.

Hope this helps!

Hello,

You have swapped the pins, in your wiring diagram LED+ is connected to GND and LED- is connected to 40mA @ 19.2V.

LED+ will need to be supplied 40mA @ 19.2V

LED- will need to be connected to GND

148
Hello!

Based on the wiring diagram you provided, it would appear that you do not have the displays LED-Anode (LED+) or LED-Cathode (LED-) connected to anything.

LED+ will need to be supplied 40mA @ 19.2V

LED- will need to be connected to GND

Hope this helps!

Be sure to also look up the Arduino UNO's pinout when you begin to wire up your display  ;)

Hello Joseph,

I recommend you use the 4-wire SPI interface when first starting out  8)

The serial interface pinout can be viewed on page 4 in the displays datasheet:

http://www.newhavendisplay.com/specs/NHD-1.5-128128UGC3.pdf

Be sure to take special note of the MPU Interface Pin Selections table, see page 4. Pin BS0 & BS1 will determine the interface selection.

E.g. In your case when using the 4-wire SPI interface BS0 and BS1 will both need to be tied LOW (GND).

Finally, you will need to modify the Arduino_OLED_128128.ino file so it selects the correct interface.

Edit line 48 from:

Code: [Select]
const unsigned char interface = 1;    // 0 = 8-bit parallel (6800 mode) interface; 1 = 8-bit parallel (8080 mode) interface; 2 = 4-wire SPI interface
To:

Code: [Select]
const unsigned char interface = 2;    // 0 = 8-bit parallel (6800 mode) interface; 1 = 8-bit parallel (8080 mode) interface; 2 = 4-wire SPI interface
Hope this help!
