Hello everybody,

i have a simple question but i can't find any answer for that.

So my question is: Support the I/O pins of the Propeller a open collector mode so that i can use external pull-ups? For example for a I2C Bus?

Best Regards

Flo

    Hello fbeek

    to use a pin as open collector, you just set the output fixed to low, then control it with the direction register.
