Post by: semed 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

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);
}
