Pov Help

Post by Andiroo »

Hello i have built my own pov using a 16f84a

I just need to know what frequency should the LED's blink at for this to work correctly? I am using a 4mhz crystal and i've set the blink speed to 1 millisecond 0.001 hz? (i've no clue really ;))

Here is my pro basic code:

'****************************************************************

'****************************************************************
speed var WORD 'speed at which the leds flash
speed = 2
tracking var BYTE 'space between each letter
tracking = 5

main:
TRISB = 0
loop:
PORTB = %00011111
PAUSE speed
PORTB = %00000101
PAUSE speed*3
PORTB = %00000001
PAUSE speed
PORTB = %00000000
PAUSE speed

PAUSE tracking
goto loop
end
