I2C between pics..

[sirvo]

Hello !!

The 16F877 has a built-in I2C communication.
The 16F628A has not..

Is it possible to create a comm. using I2C, where 877 is the master and 628A the slave?

Can I use the commands I2C write and read?

How? (sorry)..

Thanks!

PBP has built in I2C communication. If the PIC has a couple of free pins and it's supported by PBP, then your PIC has I2C capabilities (albeit software driven).
What PBP doesn't have is both master and slave capability thru PBP; Master mode only.
If you're looking for I2C slave, try this:

Haven't tried it myself, but it looks viable.
