RE: [AVR-Chat] Hardware i2c with atmega 32

Hi
Lee,
This
library: http://hubbard.engr.scu.edu/embedded/avr/avrlib/ has
some i2c routines to support both interrupt driven and non-interrupt driven
hardware TWI.
I was
able to get it up and working fairly easily.

Subject: [AVR-Chat] Hardware i2c with atmega 32Hello, I am toying around with an mcp23016 (i2c port expander) with my atmega 32.I have everything hooked up right.. but lack sample code for hardware i2c (as I have heard this is very diff from software i2c).Does anyone have any stripped down code (code just to handle 1 device on the i2c) for the avr to be the master on an i2c bus?thanks-Lee
