Pattern

I succeeded in creating a two part pattern loop. An issue was that blanking the image in between each shift caused the LED to be less bright. By adding a delay the impact of the blank could be reduced, however, initially there was too much delay and the pattern seemed to be blinking. The correct code is as follows:

PatternDelay
  call Blank
  movf p1,w
  movwf PORTC
  movf p1+1,w
  movwf PORTB
  call SmallDelay
  call Blank
  movf p2,w
  movwf PORTC
  movf p2+1,w
  movwf PORTB
  call SmallDelay
  decfsz delay+1,f
  goto PatternDelay
  decfsz howlong,f
  goto PatternDelay
  retlw 0

Here the two patterns are in p1 and p2. As you can see it is relatively easy to extend to more patterns. The next step would be to write an application that can find the minimum sets needed to display a certain pattern.
