when using i2c, i recommend to select i2c master and slave in a way, =
that main traffic is sent from master to slave. this gives you an easier =
i2c handling (slave does not need to slow down access speed).
for the slave, I recommend to use the pic's built in i2c interface, =
which is interrupt controlled (there is an application note from =
microchip).
for the master, you can use a bit bang routine, which, I think, is =
easier to handle than the interrupt driven i2c master interface, if =
there isn't a high data rate to be transferred.
unfortunately, I have no basic code.
