HOW TO PRINT CHARACTERS ON NHD-3.12-25664UCB2 DISPLAY
« on: February 04, 2018, 04:47:11 PM »
I am wondering how to print Ascii characters on this display given a font table
I am not sure which of the functions in the example code to print characters on the display screen
Can  anyone describe for me how to get characters on the screen I am not familiar with working with this kind of display

Steps:

1. write one pixel
2. Using this write a single character
3. using this write a string

thanks for your response Balahji
 mine has 119 columns by 127 rows and its 460 x64 dot matrix
I ve read the data sheet and I ve been playing around with the controls I am able to fill the screen with commands like the one below but i am still not sure how to go to a specific address and turn on a pixel there
would you be able to describe to me how to turn on a single pixel at a specific address on the display
thanks again

Set_Column_Address_25664(0x00,Max_Colmn);
   
   Set_Row_Address_25664(0x00,Max_Row);
 Set_Write_RAM_25664();
 for(f=0;f<Max_Row/2;f++)
  {
     writeLCD_data(0xff);
}
