S2 schematics?

ratronic

Is there a schematic posted for the S2? I can tell some of the things from the example code posted like the encoders are hooked to pins a13,a14 etc, but it would be nice to see a schematic of the S2.

Well - I talked to tech support today and they said they didn't have a schematic available for the S2 yet. But I can still gather most of what I need to know from the spin programs included with the S2 graphical user interface.

Attached is a schematic which was current as of 18 October. Some resistor values may have changed since then.

Thanks for that Phil!

Edit: I found everything I needed with that - Thanks again Phil!

Phil, the obstacle detector on that schematic is labeled 38khz. Can that be used for detecting ir remote code pulses?

Yes.

Then that will be my first program (probably crude) running around the Scribbler2 with a compatible Sony tv remote! This little robot has alot of features, I really like the way the adc's were set up. Sorry for all the questions, I'm just excited to play with my new toy when I get it. Phil or Parallax, can you describe the function of the idler_rx ang to the adc?

"ang" in the schematic stand for "analog", not "angle". The idler wheel has three small holes in it that make and break an IR beam as it rotates. The output from the IR detector is read via one of the multiplexed analog inputs.

Thank you Phil
