Programming PIC Microcontrollers in BASIC - mikroElektronika

Using the previous scheme, we could display a sequence of nine digits like this:

program seven_seg_onedigit

dim i as byte

' Function mask returns mask of parameter 'num'

' for common cathode 7-seg. display

sub function mask(dim num as byte) as byte

select case num

case 0 result = $3F

case 1 result = $06

case 2 result = $5B

case 3 result = $4F

case 4 result = $66

case 5 result = $6D

case 6 result = $7D

case 7 result = $07

case 8 result = $7F

case 9 result = $6F

end select

end sub

main:

INTCON = 0 ' Disable PEIE, INTE, RBIE, T0IE

TRISA = 0

TRISB = 0

PORTB = 0

PORTA = 2

for i = 0 to 9

PORTB = mask(i)

Delay_ms(1000)

next i

loop until false ' Endless loop

end.

Purpose of the program is to display numbers 0 to 9 on the ones digit, with 1 second delay. In order to display a number,
