OLEDs / Re: NHD-0216AW-IB3 I2C help
« Last post by Saurabh_B on October 18, 2017, 09:40:28 AM »
Hello,

You would only need to send the start condition once, and you would only need to send the address once after this start condition.

You will however need to send a "command byte" between each data byte sent. I would recommend looking at Figure 5-7 of the Controller datasheet.
This can be found on page 11 here: http://www.newhavendisplay.com/app_notes/US2066.pdf

This command byte would need to be sent between any instruction/data byte sent to the display, and it allows you to change the D/C# bit which determines whether the following byte that follows will be used as data or an instruction.

OLEDs / NHD-0216AW-IB3 I2C help
« Last post by sweit on October 18, 2017, 07:26:24 AM »
Hello,

I'm trying to interface an NHD-0216AW-IB3 to a dsPIC30F4013. This is the first time I've ever used the I2C interface and I have a question. In the initialization, do I need to send a start and stop condition before every command and data byte? Also, do I need to send the device address before every command and data byte?

Thank you,
Steve

I'm sorry you are having trouble with this display.
Do you have a schematic for how you are connected to the display?

I'm sorry you are having troubles with the display.

Do you have a datecode printed on those cables for the CTP?

Morning,

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

Hope this helps  ;)

Hi, I have an Arduino Mega 2560 and the NHD-4.3RTP-SHIELD-N display.
Instead of plugging the shield in, I would want to connect them via wires.

Which pins on the shield need to connect to the Arduino.

Thanks a lot!

Ferrite and resistor you must place close as possible to clock (emission) source. In this case I think that your I/O port in microcontroller.

TFTs / FT5336 problem with sensitivity and gesture
« Last post by tiro on October 16, 2017, 04:47:53 PM »
At first... hello all. I try to run display with this CTP but pdf are poor...
Now, small problem. Gesture register still give back 0, no matter what I draw by finger. It's normally?
And here is my big problem. I have three display, one work ok, but other two rages when I only touch it. FT cannot decide that I touch it by one or more finger, similar is with XY position. Is possible to adjust senstivity or change treshold point?

I find also pdf for FT5306 where I see register 0xA6h (firmware). In good module I see here 7, in bad is 6. But I'm not sure that is good way to read this register who I don't see in screen pdf (where is not write directly but is on FT5336)

OLEDs / Re: NHD-0420CW-AB3 max low voltage supply?
« Last post by Saurabh_B on October 16, 2017, 08:04:26 AM »
For 3.3V operation you can pull the REGVDD low, the max voltage at this level will be ~3.6V

OLEDs / NHD-0420CW-AB3 max low voltage supply?
« Last post by jeff on October 14, 2017, 02:55:37 PM »
Hi, I'm new to Newhaven, using a NHD-0420CW-AB3.  The data sheet says I can tie REGVDD low and supply "2.8V," but 2.8 is kind of an odd number.  Can I officially use 3.0V or 3.3V?  The cover page of the datasheet says "2.4V~5.5V Supply Voltage."  What exactly does that mean?  What is the max recommended voltage when REGVDD is low?

Thanks,

Jeff
