Steve,

Thanks for looking at the code.  A few Si570 questions since you and Pete have built your Brainard boards.

The schematic shows either an AC or a DC connection.  For the LVDS should we use the AC connection?

In the W0CNN code he has two I2C flavors:  TWI and bit-bang.  From scanning the data sheets it appears that the ATmega168 has a full fledged TWI but the ATmega169 is only partially implemented.  Should we use the TWI only for th 168 and the bit-bang approach for 169?  Would it hurt to use the bit-bang for both?  By the way I didn't know what TWI meant until I wikied it, so I may have misunderstood the data sheets.

Thanks and 73
Rich, N3III
