BIGdsPIC6 Development System 

MikroElektronika

page

17.0. 2x16 LCD 

The

 BIGdsPIC6

 development system provides an on-board connector for the alphanumeric 2x16 LCD. This connector is linked to 

the microcontroller via ports PORTB and PORTD. Potentiometer P1 is used to adjust display contrast. Switch LCD-GLCD on the DIP 
switch SW11 is used to turn the display backlight on/off.
Communication between the LCD and the microcontroller is performed in a 4-bit mode. Alphanumeric digits are displayed in two lines 
each containing up to 16 characters of 7x5 pixels.
