BOOSTXL-DRV8323RS: How to change iDrive setting using the Instaspin

Part Number: BOOSTXL-DRV8323RS
Other Parts Discussed in Thread: MOTORWARE

Hi,

We a re seeing some ringing on the high and low side turning off, a possible mean is to adjust the iDrive.

May I know how the iDrive setting can be adjusted on DRV8323RS using the Instaspin code?

Can it be done on the fly using the GUI?

Thanks,

Christina

    Hello Christina,

    You can adjust IDRIVE on the DRV8323RS BoosterPack using the GUI associated with that EVM.

    For Instaspin support, I'm reassigning this post to C2000.

    Hi Christina,

    You may download the drv8323rs patch as the link below for motorware v18, you could find some example project for BOOSTXL-DRV8323RS in the patch. And then you may add some lines code as below to change the IDRIVE per your h/w specification.

    gDrvSpi8323Vars.Ctrl_Reg_03.IDRIVEP_HS = ISour_HS_0p500_A;
    gDrvSpi8323Vars.Ctrl_Reg_03.IDRIVEN_HS = ISink_HS_0p500_A;
    gDrvSpi8323Vars.Ctrl_Reg_04.IDRIVEP_LS = ISour_LS_0p500_A;
    gDrvSpi8323Vars.Ctrl_Reg_04.IDRIVEN_LS = ISink_LS_0p500_A;
    gDrvSpi8323Vars.WriteCmd = true;

    HAL_writeDrvData(halHandle,&gDrvSpi8323Vars);
