Programming question, all outputs on?

[gadget-evilusions]

Is there a way to turn all the outputs of the prop-1 on at once, and then off at once. I am making led boards that I will be stobing all on at once and all off at once. P7 is a pot to give me a variable off time between flashes (between 50ms and 1000ms). I belive my on pulse length will only be about 50ms. I have a working program to turn P0 on and off according to my pot, but I couldnt think of an easy way to turn them all on, or all off at once.

That's an easy one: just write your outputs to the PINS register (renamed Leds in the program below).  Only those pins that are made outputs (by setting the associated bit in DIRS to 1) will be affected.

Oh geez. Now I feel dumb. Thanks for the help Jon.

Don't kick yourself; you asked, you learned, you're now a better Prop-1 programmer!   ;D
