Hello Chris,

Thank you so much for sharing! I'm sure your sample code will come in handy for Parallax users  8)

Hello,

The CO (Continuation) signal is just telling the display that there is going to be continuous I2C transmission. Rather than sending a start condition before each byte.
 
You can think of CO as a short cut,  e.g. instead of sending a start condition every time you wish to send continuous data you just set CO.  8)

Hello,

NHD-C12864A1Z-FS(RGB)-FBW-HT1 is a COG display, however the glass is attached to a pcb which contains current limiting resistors, please see page 3 in the displays datasheet.

Graphic LCDs / Re: NHD-C12864A1Z-FS(RGB)-FBW-HT1 heater
« on: April 28, 2015, 08:03:48 AM »
Hello,

Thanks for reaching out. There are multiple ways to control the displays heater.

1. The simplest method is to apply +12V to pin 14 and Gnd to pin 1.

2. Second you can use an external circuit to control the heater (see page 5), using a heater circuit can be energy efficent and can be configured to accommodate a variety of energy requirements.

Hope this helps!

Hello Rob,

Thanks for reaching out. NHD-C12864A1Z-FS(RGB)-FBW-HT1 contrast can be controlled via software using the Electronic Volume Commands and V5 Voltage Regulator Internal Resistor Ratio Set. Please refer to page 37 - 38 in the displays controller datasheet.

Hello,

I recommend double checking your initialization, please use our example initialization sequence in the display's datasheet, page 8.

If possible can you please provide your code, thanks!

Hello,

Thank you for the additional information. Your display appears to be hooked up correctly which is good! The fading could have been caused due to exposure of moisture.

The steam radiator heating system or having the unit placed closely to leaky doors / windows could slowly cause fading of the pixels. I recommend trying to seal the enclosure a little better just as a precaution.

Hope this helps!

Hello,

This is not typical behavior, can you please tell me how you are driving the display?

Can you also list what kind of environment this display is in?

Thanks!

Hello,

We have verified the correct configuration for 5V operation, please see the table attached. The updated spec will be available later today, I apologize for the inconvenience.

Thanks.

Hello,

I'm sorry, unfortunately we can not give you an exact response time without physically testing the display under those conditions.

You are correct that the response time will drop in very cold temperatures, but by how much? You will need to conduct some testing  8)
