I2C and SPI are competing standards. No they're not compatible. However it
is pretty easy to bit-bang I2C; just use open-collector outputs (or drive
the SDA and SCL lines with NPN transistors -- float the collectors to +V and
connect the emitters to ground; the output will be taken from the junction
of the collector and the resistor and the output will be the opposite of
what you spit out to the port.
