MCP4725 breakout board

Other Miscellaneous

I just wanted to let you know that the reference firmware from the hookup guide for this breakout board seems to have the wrong I2C address listed. The source code (and a post here in the forums) says to use address 0x60 or 0x61, depending on the solder jumper.

However, according to the datasheet (and the test I just performed), the address should be 0xC0 or 0xC1. Or is Arduino somehow mangling the address? I am using bare metal with my own i2c driver.

Please disregard, I see the difference - Arduino is looking at the 7-bit address which gets left-shifted by one for the R/W bit. So the resulting byte sent on i2c is 0xC0 etc. depending on read/write and solder jumper.
