    Hi,

    Download C2000ware if you've not. Navigate to following directory for I2C example code:
    C:\ti\c2000\C2000Ware_1_00_05_00\device_support\f2803x\examples\c28\i2c_eeprom

    Let us know if you find difficulty in modifying the example code wrt the DAC.

    Regards,
    Gautam

     i can get also from C:\ti\controlSUITE\device_support\f2803x\v125\DSP2803x_examples_ccsv4 how to connect i2c
    but know i can not clear about DAC of HVM KIT SCH attached below. i know i can use either 1(red line circle) or 2 for DAC purpose, i am not clear about SN74LVC2G17 BUFFER ic(FIRST question can this ic used as DAC device like MCP4728 IC?)

    second question

    (from induction motor control PWMDAC driver macro used for the input of dac pins to hvm kit, but can i reject this PWMDAC drive macro code and can i observe the dac output ? please correct me my answere for this i think SN74LVC2G17 ic used as dac device with only PWMDAC drive code, without this drive code it is not give dac output)

    third question

    if the 1(red line circle not used as dac without PWMDAC drive macro code can i 2(red line circle) with the circuit after i assemble on PCB(file name: EXTERNAL DAC PCB) also how to programe when i connect external i2c to the kit )

    thank you for your helping me.

    Hi Tesfaye,

    Since you posted a similar question about the interface between hv-kit and external DAC. We have replied to these questions in your another thread. We would like to close this thread first if no any further questions. Thanks.
