P1 DIP40 Bare bones

Digikey are showing 1000+ in stock and I'm thinking of relieving them of a few.

I like DIP :smile:

I should have a bare-bones schematic for this device but darned if I can find it. Please point me in the right direction :+1:

    Please disregard....Since realised that I have @Coley's design which is really close to what I need :+1:

  • Well, think again.
    Mouser has them significantly cheaper (in singles). If that is of any importance to you, that is.

    Suggestion: Put pull-ups on both I2C pins (many Parallax schematics show the pull-up on P29/SDA). Some I2C drivers, like mine, follow the I2C rules and do not drive the SCL line high (the Propeller does when loading code from the EE on boot-up).
