DRV8308EVM: Registers configuration using SPI

Part Number: DRV8308EVM

when motor running using PWM mode setting and try switching to register mode and write configuration ,the motor stopped . i can't understand what happen ? and how to write registers and control speed 

  • Gehad,

    Thanks for posting on the MD forum!

    Did you use the READ ALL button to first read the registers?

    Which registers are you trying to change?

    Which version of the GUI are you using? Is it the downloaded installer version? or the online version?

    Regards,

  • thanks for your response , i didn't use read all button 

    i tried to write 0x00 register

    i used version 1.0.1  online 

    is there any sequence to do that ? and it appears any message to indicate that fail or success ?

  • Gehad,

    I would recommend first using the Read All button to get the default values loaded from the device into the GUI, then make your changes, then write the register you want to modify.

    There is no success/fail check but if you use the Read All button you should always see the values that are stored in the device.
