Character LCDs / Re: NHD-0216K3Z-FL-GBW-V3 outputting 5V on data pin
« on: December 05, 2016, 07:57:30 AM »
Iím sorry to hear about the trouble you are having with the NHD-0216K3Z-FL-GBW-V3. All displays are tested before they leave our facility, chances that it is DOA is fairly low.

First to enter the RS‐232 mode, both R1 and R2 should be open. Can you please confirm that both R1 and R2 are open on the back of the display?

Second, can you please confirm you are using matching the displays BAUD rate? By default the BAUD rate is 9600, and is changeable with a command function (see page 7 in the displays datasheet).

Third, the RS232 signal must be 5V TTL compatible, can you also confirm that this is what you are using for the communication?

Finally, can you provide me with a detailed pin-out diagram so I can verify your connections.

Evening,

The LCD and backlight pins should be soldered directly onto a thru-hole connection on a PCB (not a cable).

For your convenience I have attached the recommended footprint below  ;)

Morning Eric,

Iím sorry to hear about the trouble you are having with the NHD-0216CW-AB3. All displays are tested before they leave our facility. We have never experienced this issue, both displays utilize the US2066 controller and share the same timing.

Can you provide me with a detailed pin-out diagram so I can verify your connections / pull-ups?

Morning,

The backlight requires a constant-current mode boost converter E.g. FAN5333BSX

What source are you using to power the backlight? If you have a DMM can you please post the current draw and voltage?

Finally the Data Enable & Display on/off signal will have no affect on the backlight.

Glad to hear you got your display up and running!

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

Morning,

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

Thanks!

OLEDs / Re: NHD-0216CW-AB3 and an Arduino Micro

Glad to hear you are up and running!

Glad to hear you are up and running! The library was originally written with the old IDE, and since then the avr-gcc compiler has changed and certain keywords/datatypes give errors in the new Arduino IDEís.

Morning Tim,

Can you please try installing version 1.0.6 of the Arduino IDE?

https://www.arduino.cc/en/Main/OldSoftwareReleases

It appears there was a change in the syntax, I'll look into this change further and provide a fix.

Thank you for the information, since the NHD-2.7-12864UCY3 is a Monochrome Passive-Matrix OLED display unfortunately the slight change in luminance is a characteristic of this OLED technology. To illuminate any particular pixel line in a passive-matrix display, electrical signals are applied to the row line and column line. The more current pumped through each pixel diode, the brighter the pixel.

Iíve heard of customers implementing some software correction routines to help with this issue when using monochrome OLED displays, by way of increasing/decreasing the grayscale (brightness) value of a particular pixel based on how many pixels are ON in that row.

Evaluation Tools / Re: NHD-4.3CTP-Shield library appears to be invalid
« on: October 19, 2016, 08:12:09 AM »
Morning Tim,

For more details, especially for first-time library installers, check out the following tutorial at https://www.arduino.cc/en/Guide/Libraries.

The FTDI_FT801 library which is available for download on our Github page has been tested and verified to work. I verified correct operation this morning using an Arduino Uno and the NHD-4.3CTP-SHIELD-V (Arduino V. 1.0.6).

Has an error occurred while uploading the sketch?
