28027F Controlling DRV8301 through I2C

Other Parts Discussed in Thread: DRV8301, MOTORWARE, CONTROLSUITE

Hi,

I'm using the Piccolo 28027F launchpad, and I would like to use the I2C to control the DRV8301. Is it even possible ?

I tried to use the 2802xI2C eeprom example, with little success. I cut the jumpers on the launchpad to use the I2c ad SPI separately but now I have no idea hot to include the I2C into the motorware code???

I havent seen anything similar being done on the forum.

Help would be greatly appreciated.

Thank You

    Hi Rok,

    DRV8301 does not support I2C but supports SPI and here is the info:

    DRV8301 said:
    The SPI interface provides detailed fault reporting and flexible parameter settings such as gain options for current shunt amplifier, slew rate control of gate driver, etc.

    Try with the "spi_loopback" example in controlSuite.

    Regards,

    Gautam

    Hi Gautam - thank you for the reply - maybe I wanst clear enough what I want to do - well I definitely wasn't clear enough. I dont want to control the DRV8301, I want to communicate with  the launchpad via I2C, and send commands to control the brushless motor, and receive data from the motor.

    I opened another topic on the forum, and explained the issue in details - here it is: http://e2e.ti.com/support/microcontrollers/c2000/f/171/t/322178.aspx

    Thanks again for the fast answer.
