TFTs / Re: NHD‐3.5‐320240MF‐ATXL#‐T‐1 Touch Signal

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 Facotl,

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

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);
   
}

  command(0x23);                    // Set Fade out Mode

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>;
+ };

Character LCDs / Re: NHD-C0220BiZ-FSW-FBW-3V3M Problem -- Doesn't power on
« on: December 10, 2015, 08:07:52 AM »
Hi Sukho,

If you would like to power on the displays backlight you will need to apply 3V @30mA (Typ.) respectively to the Anode and Cathode pins.

The wiring diagram (See page 4) shows the anode A connected to power (upward facing triangle) and the cathodes are shown connected to ground (downwards facing triangles).

Hi Sukho,

To answer your question, No you will not see any characters appear on the LCD. Before you can really use the LCD, you must initialize and configure it. This is accomplished by sending a number of initialization instructions to the LCD.

Hello Sukho!

Iím sorry to hear about the trouble you are having with NHD-C0220BiZ-FSW-FBW-3V3M. Before you can really use the LCD, you must initialize and configure it. This is accomplished by sending a number of initialization instructions to the LCD.

Please see our "Example Initialization Program" listed on page 11 in the displays datasheet:

http://www.newhavendisplay.com/specs/NHD-C0220BiZ-FSW-FBW-3V3M.pdf

Next, it would be helpful to verify your wiring / pinout. Feel free to post it below.

Finally the pin connection / wiring diagram in the displays datasheet is correct. The pin numbering listed in the mechanical drawing 8 - 1 (left to right) is there to help distinguish the correct pin order.

Please following the pin description table listed on page 4 in the displays datasheet and take special note of where pin 1 is located on the physical display when wiring.

Hope this helps!

Hello,

I highly recommend you check out the controllers datasheet, see page 20 - 21:

http://www.newhavendisplay.com/app_notes/SSD1351.pdf

Table 8-5 and Figure 8-5 should clear things up  ;)
