TFTs / Re: FT5336 problem with sensitivity and gesture

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

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

TFTs / Re: NHD-4.3RTP-SHIELD-N Pinout

Morning,

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

Hope this helps  ;)

TFTs / NHD-4.3RTP-SHIELD-N Pinout
« Last post by skmfg on October 17, 2017, 02:30:25 AM »
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

Evaluation Tools / LED backlight at 40mA
« Last post by JeffD on October 12, 2017, 03:29:30 PM »
Hello,
Is there a way to modify the NHD-3.5-320240MF-VIDEO Board V1.1 to have 40mA output for the backlight rather than 20mA?

Replying to my own to add an update for anyone else that has a similar problem...

My SPI code was faulty. I got in touch with Newhaven, and was sent some updated code that woke up the display. I'm modifying the everloving snot out of said code and will post a library/demo once I have a good set of utility functions built.
