a nice diagram of a ZX40n showing each pin annotated with its function ? I can't find one in the zx40n hardware reference, only parts showing supporting circuitry.

I like to use such a thing to scribble on during development

thanks

There is no one diagram that indicates which pins are used for every function. You can start with the package diagram that is in the Atmel datasheet (excerpted below) and add notes as you go.

Things to keep in mind:
  • The RxD0/TxD0 pins are used for Com1
  • The RxD1/TxD1 pins are used for Com2
  • Pins B.4-B.7 are used for SPI
  • Pins C.0 and C.1 are used for I2C
  • Pins D.2, D.3 and B.2 are used for INT0, INT1 and INT2, respectively
  • All of the pins marked PCINTnn are possible pin change interrupt pins
  • Pins D.7 and D.6 are 8-bit PWM channels 1 and 2, respectively
  • Pins D.5 and D.4 are 16-bit PWM channels 1 and 2, respectively
  • Pin D.4 is the standard OutputCapture() pin
  • Pin D.6 is the InputCapture() pin
  • The analog inputs are A.0 through A.7
