工具/软件：

您好：

我遵循 “用户指南 电机控制 SDK 通用工程和实验“文档中的“3.2.10 BOOSTXL-DRV8323RS 设置“来设置 LAUNCHXL-F280025C 和 BOOSTXL-DRV8323RS。

为了验证 LAUNCHXL-F280025C 是否通过 SPI 与 BOOSTXL-DRV8323RS 成功通信、我执行了以下步骤：

我修改了源代码、如下所示。用途：将数据写入 DRV8323RS 的控制寄存器后、我读回这个相同的控制寄存器。

bool HAL_MTR_setGateDriver(HAL_MTR_Handle handle)
{
    ...
    ...
    drvicVars_M1.ctrlReg02.bit.OTW_REP = true;
    drvicVars_M1.ctrlReg02.bit.PWM_MODE = DRV8323_PWMMODE_6;

    drvicVars_M1.ctrlReg05.bit.VDS_LVL = DRV8323_VDS_LEVEL_1P700_V;
    drvicVars_M1.ctrlReg05.bit.OCP_MODE = DRV8323_AUTOMATIC_RETRY;
    drvicVars_M1.ctrlReg05.bit.DEAD_TIME = DRV8323_DEADTIME_100_NS;

    drvicVars_M1.ctrlReg06.bit.CSA_GAIN = DRV8323_Gain_10VpV;         // ADC_FULL_SCALE_CURRENT = 47.14285714A
//    drvicVars_M1.ctrlReg06.bit.CSA_GAIN = DRV8323_Gain_20VpV;       // ADC_FULL_SCALE_CURRENT = 23.57142857A
    drvicVars_M1.ctrlReg06.bit.LS_REF = false;
    drvicVars_M1.ctrlReg06.bit.VREF_DIV = true;
    drvicVars_M1.ctrlReg06.bit.CSA_FET = false;

    drvicVars_M1.writeCmd = 1;
    HAL_writeDRVData(handle, &drvicVars_M1);
    SysCtl_delay(1000U);

    drvicVars_M1.writeCmd = 1;
    HAL_writeDRVData(handle, &drvicVars_M1);
    SysCtl_delay(1000U);

    // My code to read control register after write data
    drvicVars_M1.readCmd = 1;
    HAL_readDRVData(handle, &drvicVars_M1);
    SysCtl_delay(1000U);
    ...
    ...
}
