Programming PIC Microcontrollers in BASIC - mikroElektronika

LCD connects to microcontroller via 4-bit or 8-bit bus (4 or 8 lines). R/W signal is on the ground, because

communication is one-way (toward LCD). Some displays have built-in backlight that can be turned on with RD1 pin via

PNP transistor BC557.

Our following example prints text on LCD via 4-bit interface. Assumed pin configuration is default.

program LCD_default_test

dim Text as char[20]

main:

TRISB = 0 ' PORTB is output

LCD_Init(PORTB) ' Initialize LCD at PORTB

LCD_Cmd(LCD_CURSOR_OFF) ' Turn off cursor

Text = "mikroelektronika"

LCD_Out(1, 1, Text) ' Print text at LCD

end.

Our second example prints text on LCD via 8-bit interface, with custom pin configuration.

program LCD8_test
