Hi,

As far as I understand this board (DAC7678evm) communicates through i2c interface.
Here are some examples on how Beaglebone Black uses I2C to communicate with slave devices:
elinux.org/Interfacing_with_I2C_Devices
beaglebone.cameon.net/.../i2c-devices

These examples are used in Linux File system. You can also use i2c commands in u-boot environment.

Best Regards,
Yordan

Thanks for reply.
DAC7678evm has octal DAC and it has ADDR0, ADDR1, LDAC, RSTSEL, TWOC except SCL & SDA . All these pins are to be configured in a proper sequence. I am not getting how to configure it.

I have asked there and someone has replied " The DAC7678 device uses I2C communication. You can post to the Microcontrollers/Processors forum to get example library code for standard I2C communication. "

There are no example drivers for this DAC in the Sitara Linux SDK.
