These two LCD modules can be bought in our online shop. You’ll need the interface described below and a PIC microcontroller to get these LCD modules running.
PIC example Source code (CCS C) , pcb layout and schematics (Eagle) available. Last update: March 24, 2007.
PIC software example: routines
| ccs routine | example | explanation |
| LCD initialization | dt_lcd_init(); | init parameters needed after power on |
| Clear screen | dt_lcd_clear_screen(); | resets all pixels, needed after power on |
| Cursor position set | dt_lcd_gotoxy(0,5); | goto cursur location x= 0..127 PIXEL COLUMNS // y= 0..7 CHAR. ROWS |
| Write text to LCD | printf(dt_lcd_printchar,” DisplayTech LCD”); | show simple unformatted text |
