Hey all. I've been enjoying my learning endeavors with the PICAXE 08M2. I have an application in mind which more or less requires the smallest form factor I can work with, and 08M2 has so far seemed promising (re-learning BASIC has been worth it no matter what!). I'm trying to feed 4 switch states into the 08M2, and this has worked fine so far. However, getting the switch states as bits off of the PICAXE and on down the I2C bus is looking to be more problematic. I have run into two problems that give me pause before I plunge in.
Thanks,

- The pinout says that physical pins 5 and 6 (C.2 and C.1) are reserved for I2C operations, and physical 7, C.0 is OUT only. Does this mean I can only input on 3 pins if I'm using I2C on a 08M2?
- My understanding from other posts on this forum is that the 08M2 cannot operate in I2C slave mode. If this is true, what's the smallest form-factor PICAXE I can get that will run as a slave?
Thanks,
