(...) Either single pin modes allow to set each output to 1 (9V) or 0 (0V). (...) See the drive datasheet: (URL) can reach 1A peak, continuous value is lower (500-600mA) especially if both outputs are heavily loaded at the same time.

(...) Bob, I could not wait to get home from work to try this. I want to say thank you; your effort has saved me many countless hours. I loaded the Firmware, and the Program into a 1.0 RCX, and the brick worked flawlessly! On my 1.0 brick, I was (...)

(...) The toggle bit is checked in Single output mode (the documentation is not quite right for this mode) and in both single pin modes. each message is sent 5 times you need to toggle the toggle bit in every message sent. 0 1 0 1 0 1 0 1 etc. bob (17 years ago, 25-Jan-08, to lugnet.general, lugnet.technic, lugnet.trains, lugnet.robotics, FTX)

(...) This is great news indeed, thank you for posting. Has anyone tried the rc train remote on a power function reciver to see if it uses the single output pwm control signals? If not, hopefully the new RC train system will be compatible. It also (...) (17 years ago, 25-Jan-08, to lugnet.technic, lugnet.trains, lugnet.robotics, FTX)

(...) I don't have BrickOS, but I have been playing with the protocols in NBC. I got the twin-motor PWM mode to work in tests, and the original 'Combo direct'. But I can't get 'Single output' or either of the 'Single pin' modes to work. Have you had (...) (17 years ago, 25-Jan-08, to lugnet.general, lugnet.technic, lugnet.trains, lugnet.robotics, FTX)

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 reciever moduals. You do not need to install (...) (17 years ago, 25-Jan-08, to lugnet.general, lugnet.technic, lugnet.trains, lugnet.robotics, lugnet.announce, FTX) !
