Looking for some info on smart pins etc

Bob Drury

Just received edge P2 looks like a lot of good work . Congrats. Just a couple of questions.
1) Was trying to work through smart pins and was wondering what was going on with “pintoggle()” and “pinwrite()”. There are 4 registers Mode,x,y,z are these written too with the methods (spin2 commands)? Is there some info on what These commands are doing in the background?
2) Some documentation on “debug” stated that Propeller Tool ver 2.5 is required. The Blinky program runs but the serial “Hello” never appears in the PST
Terminal. Does Propeller tool ver 2.4 just ignore any debug commands? The PST objects(jm_format_strings_demo.spin2) seem to be working fine, I would assume debug is using a custom piece of the serial interface. Is debug not in ver 2.4?
3) Propeller P1 manual was extremely well done. Is there a plans for a similar P2 manual. The Manual is a work in progress from what I can ascertain from
The forum and website is there a date to check back for purchasing a copy?

This is a simple pin object.

When you enable a smart pin, you no longer have basic IO control over it. Some smart pin modes, e.g., PWM, need to make the pin an output so there is a configuration bit for that. When the smart pin field of the pin register is not 0, the dir bit for the pin is used to enable that smart pin mode. Yeah, it can be a little confusing at first.

I posted an archive called jm_p2_starter in this thread:

Some of the objects use smart pins -- this should help you get a handle on them (be sure you have the Spin2 docs open, too).

Thanks DigitalBob and JonnyMac for responding. The info will keep me going for a while,

Just in case you missed it, the Propeller 2 documentation page at:

has links to some helpful documents.
