Programming PIC Microcontrollers in BASIC - mikroElektronika

The following example toggles LEDs of PORTB every second.

program LED_Blinking

main:

TRISB = 0 ' PORTB is output

PORTB = %11111111 ' Turn ON diodes on PORTB

Delay_ms(1000) ' Wait for 1 second

PORTB = %00000000 ' Turn OFF diodes on PORTB

Delay_ms(1000) ' Wait for 1 second

goto main ' Endless loop

end.

7.2 Seven-Segment Displays

Seven-segment digits represent more advanced form of visual communication. The name comes from the seven diodes

(there is an eighth diode for a dot) arranged to form decimal digits from 0 to 9. Appearance of a seven-segment digit is

given on a picture below.
