im trying to flash 4 leds with multiple flash patterns but i need to know the command(s) to flash all 4 of them at the same time. everything i try flashes them in sequence. please help!

 

One way to do it would be to set up four counters, and an "LED image" variable.
Load the counters with different numbers.
Run a loop like this:

Loop:
       Decrement counter1
       if Counter1 == 0 then
            Reload Counter1
            Toggle LED1 bit in the LED image
       end if
       Repeat for the other counters
       Send the LED image to the LED port
endloop

Using the image allows you to send out different ON and OFF commands simultaneously.
