OLEDs / Re: NHD-0220CW-AG3 Character set
« Last post by Saurabh_B on March 28, 2017, 09:19:53 AM »
Hello,

The Font Tables on our displays are defined by the manufacturers of the controllers, in this case it would be the company that manufactures the US2066 controller.

The best solution for requiring multiple characters would be to use a graphic OLED display.
However for this one you would need to create a font table as well.

Hi again.
Luckily I found my mistake why I could not write data to CGRAM.
In the function data_write() the RW signal was wrong, RW_HIGH should be RW_LOW.  ::)


Unfortunately we really need to set more than 8 individual characters, minimum 13 chars.

Is there a possibility to get a display with a modified software (modified font set)?

Best regards.

OLEDs / NHD-0220CW-AG3 Character set
« Last post by OS on March 28, 2017, 02:49:57 AM »
Hello.
We are using a NHD-0220CW-AG3 (in 4-bit Parallel 6800 interface) with the character set of ROM C.
Is it possible to overwrite the first 8 character of ROM C to add individual character?

I tried it in this way, but did not succeed. I only got strange signs on the display.

Code: [Select]

void data_write (uchar c)
{//high byte
  PORTA = (c & 0xF0);
  DC_HIGH;
  RW_HIGH;
  E_HIGH;
  wait(LCD_WAIT);
  E_LOW; //data latched
 
  //low byte
  PORTA = (((c & 0x0F) << 4));
  DC_HIGH;
  RW_HIGH;
  E_HIGH;
  wait(LCD_WAIT);
  E_LOW; //data latched
}

void command (uchar c)
{//high byte
  PORTA = (c & 0xF0);
  DC_LOW;
  RW_LOW;
  E_HIGH;
  wait(LCD_WAIT);
  E_LOW; //data latched
 
  //low byte
  PORTA = (((c & 0x0F) << 4));
  DC_LOW;
  RW_LOW;
  E_HIGH;
  wait(LCD_WAIT);
  E_LOW; //data latched
}

set_newCharToFont(void)
{
  command(0x40); //0x40 -> pos of first char in CGRAM
  data_write(0x08); //1   8
  data_write(0x10); //2   10
  data_write(0x08); //3   8
  data_write(0x00); //4   0
  data_write(0x05); //5   5
  data_write(0x07); //6   7
  data_write(0x05); //7   5
  data_write(0x00); //8   0
}

void show_char(uchar num)
{
  command(0x01); //clear display
  command(0x02); //return home
  data(num); //1 -> Read data in ROM C at pos num
}


in main.c:

set_newCharToFont();
show_char(0);



One more question:
If we need more than 8 new character in the font, would it be possible to get a display with a customized software, which contains the needed characters?

Best regards,
OS

Characters appear correctly on screen but not until long after the serial communication has finished.  Any thoughts?

Morning Laxmikant,

The NHD-5.0-800480TF-ATXL# is not a sun-readable display. We will be introducing a sunlight-readable 5.0" TFT in the up coming year.  These new displays have brightness levels and features that allow for excellent viewing quality even in direct sunlight conditions.

In the mean time feel free to check out our new 4.3" Sunlight Readable TFT:

Dear sir,

We have short listed the Display NHD-5.0-800480TF-ATXL# for our product Mobile Data Terminal. I am not sure, if this display is sunlight readable. This is essential feature requirement for our product.
Please confirm, NHD-5.0-800480TF-ATXL# is sunlight readable display.

Best regards
