Power Functions Remote

Control Power Functions from a LEGO MindStorms RCX

Now you can use your RCX to control LEGO Power Functions. That's right, the RCX can act as a PF remote control but it can do something that the PF remote can't do yet. The RCX can do PWM with your PF receiver modules.

While this is based on the BrickOS firmware, you do not need to build BrickOS to get this to work. The Windows executables, RCX firmware, and RCX program that you need are included with the release.

Note

Power Function capabilities are now available as part of brickOS-bibo.
