RE: [AVR-Chat] I2C interface question (AVR <-> ARM)

Yes, 100khz (although I have tried from 10khz -> 500khz with identical
results).

There is no "speed" configuration for the AVR since they are in slave mode
only (except when I make one a master for testing purposes...)

| Do you have pullups on both sides of the level shifter?
| 
| What speed do you have the ARM and AVR configured for?
