Morning,

The Arduino Nano is a compact and breadboard-friendly version board based on ATmega328 processor. It is more or less same functionality as the Arduino UNO but in different package (which means it won't accept any shields designed for the UNO). However since you are using NHD-1.69-160128ASC3 you can simply breadboard your project  8)

First check out the pin-out diagram for the Arduino Nano.
Link: http://bit.ly/1PF7FLp

We provide getting started code, however it is configured for the Arduno Uno. You will need to modify the sketch with the following pin configuration:

https://github.com/NewhavenDisplay/NHD-1.69-160128ASC3_Example/blob/master/examples/test/test.ino

Code: [Select]
Hardware: (Note most of these pins can be swapped)
    Color OLED Pin----------------Arduino Pin
       MOSI       ----------------  15
       SCK        ----------------  17
       DC         ----------------  12
       RESET      ----------------  13
       OLEDCS     ----------------  14
       Vin        ----------------  5V or 3.3V
       GND        ----------------  GND

Feel free to follow along with our Serial Color OLED User Guide, the only difference is you are using an Arduino Nano and will be wiring your display slightly different.

Hope this helps!

Morning Brad,

There are virtually unlimited number of ways that you can fail a radiated emissions test, below are a few tips that should help you pass  ;)

  • Ground the TFT's bezel, copper tape comes in handy
  • Utilize flat cable Ferrite core (used for FPC/FFC cable)
  • Utilize EMI shielding foils and film
  • Board decoupling

Hope this helps, feel free to contact me if you have any questions or concerns.

Morning jmasamoto,

The mapping is as follows:

Y1 = Y+ or YU
Y2 = Y- or YD
X1 = X- or XL
X2 = X+ or XR

I personally have not used the TI ADS7846, however after looking over the datasheet it looks compatible  8)

Hope this helps!

Morning kburndred,

Can you please provide a little more detail regarding the issue you are encountering with NHD-C0220BiZ-FSW-FBW-3V3M. It appears to be an initialization issue, if possible post your initialization sequence below.

Next, it would be beneficial to verify that your display is wired correctly, see page 4.
Link: http://www.newhavendisplay.com/specs/NHD-C0220BiZ-FSW-FBW-3V3M.pdf

Can you tell me what value pull-up resistors are you using on your SCL and SDA lines?

Finally, have you verified this behavior with multiple displays?

Thanks!

Morning,

It is typically preferred to supply the displays Typ. Voltage when ever possible, however in your case supplying 3.3V is perfectly acceptable  ;)

Morning,

Iím sorry, unfortunately you can only interface to NHD-2.4-240320CF-CSXN#-F via a 8-bit/16-bit parallel interface. If you are interested in a possible custom design please contact support@newhavendisplay.com for further information.

Morning Phil,

Glad to hear you're up and running! Thank you for sharing your solution so anyone else having similar problems can solve them  ;)

Morning Facotl,

Correct pin 1 starts from the left hand side, glad to hear your display is up and running  ;)

OLEDs / Re: NHD‐0420CW‐AG3 Contrast question
« on: January 12, 2016, 10:09:22 AM »
Morning Richard,

Glad to hear you have your display up and running! Regarding the Set Contrast command the margin of change is around 30-40%.

Please see the example code linked below as reference and to verify correct operation:

Code: [Select]
void contrast(){ // Adjusted contrast from invisible to full brightness
     
      command(0x02);
      command(0x01);
      disp2();
      for(int i = 127; i>0; i -=32){
     
      command(0x2A);                    //function set (extended command set)
      command(0x79);            //OLED Command set enabled
      command(0x81);          // Contrast
      command(i);
      command(0x78);                    //OLED command set disabled
      command(0x28);                    //function set (fundamental command set)
     
      delay(250);
    }
   
    for(int i = 1; i<256; i +=32){
     
      command(0x2A);                    //function set (extended command set)
      command(0x79);            //OLED Command set enabled
      command(0x81);          // Contrast
      command(i);
      command(0x78);                    //OLED command set disabled
      command(0x28);                    //function set (fundamental command set)
     
      delay(250);
    }
    command(0x2A);            // reset contrast to normal
    command(0x79);
    command(0x7F);
    command(0x78);
    command(0x28);
    disp();
    delay(700);
   
}
////////////////////////////////////////////////////////////////////////////////////////////////
// Fades out and in
void fade(){
  command(0x2A);                    //function set (extended command set)
  command(0x79);                    //OLED command set enabled
  command(0x23);                    // Set Fade out Mode
  command(0x20);                    // Set Fade out Mode (24 frames)
  command(0x78);                    //OLED command set disabled

  command(0x78);                    //OLED command set disabled
  command(0x28);                    //function set (fundamental command set)
  command(0x01);
  command(0x02);
 
  delay(1250);

Morning Peter,

We are in the process of offering a controller board which will support our Sunlight Readable and Premium 4.3" TFT displays. This will be available to our customers in a couple weeks.

In the short term, just to get things up and running you can make the modifications listed above or hold off until these new controller boards are released  :D

Hi Alex,

Sounds like an awesome project! Its a little difficult to tell by your photo, however it would appear that your pxl-clk isn't configured correctly. Can you please try and upload some additional pictures?

Finally, please review the timing below which has worked for me in the past  ;)

Code: [Select]
display-timings {
+ native-mode = <&timing0>;
+ /* Settings for NHD-5.0-800480TF-ATXL#: */
+ timing0: 800x480 {
+ clock-frequency = <45000000>;
+ hactive         = <800>;
+ vactive         = <480>;
+ hback-porch     = <40>;
+ hfront-porch    = <40>;
+ hsync-len       = <48>;
+ vback-porch     = <29>;
+ vfront-porch    = <13>;
+ vsync-len       = <3>;
+ hsync-active = <0>;
+ vsync-active = <0>;
+ };
