Pwmout On More Than One Pin

Hi all got a couple of 08M and 14M chips and been playing with PWMOUT command, to make an LED beacon effect. If I want to drive two outputs the same can I do this on a 08M chip or 14M chip?? Or could I drive a transistor and couple two leds on the output with suitable limiting resistors?

cheers

PWMout is limited to certain pins on the PICAXE chips as detailed in PICAXE manual 2 page 140.

For the 08M and 14M it states:

- Pin is a variable/constant which specifies the i/o pin to use. Note that the
pwmout pin is not always a default output pin - see the pinout diagram.
08M/14M - 2
18M/18X - 3
20X2 - C.5
28X/X1 40X/X1 - 1 or 2
28X2 40X2 - C.1 or C.2

For the 08M that is IO pin2 and for the 14M that in input 2

If you need to drive multiple devices then you need (as you mention) an external circuit such as a transistor or chip if you need extra current drive capacity.
