Connect One Ethernet shield

[dhouston]

you are using plain I/O and bit-banged serial where the polarity can be inverted instead of the microcontrolers onbaord USART?

Ahh, methinks you presume too much.

On the rare occasions when I use a PIC bigger than the 8-pinners, I use ones where the comparator inputs and outputs are exposed. I use them as inverters for TX & RX. (@Bruce: On the 16F88, this uses up 6 pins so I'm just barely violating my 8-pin limit.) Most of the PICs, PICAXEs discussed in relation to these shields qualify and the Xino designers have agreed to look into making this optional in the DS30 bootloader. You only need current limiting resistors in TX & RX and it looks easy to add these to most of the Arduino clone main boards I've seen.
