请教关于 ADE7878 SPI通讯问题

各位好:
     参考官网的ADE7878示例代码,然后发现SPI读任何寄存器都全是0XFFFFFFFF,感觉应该是没通讯上,但是又不知道问题在哪,有哪位用过的可以帮忙看下吗? 附上示例代码, 诚心请教! 有好心人可以加我的QQ:79444528或者微信solo_wen,求指导. 已经弄了两周了. 下面是我的一些详细信息:

1.硬件原理图:

已经量VREF(C28)两端电压为1.19V

2.软件:
SPI配置:
void MX_SPI1_Init(void)
{
  hspi1.Instance = SPI1;
  hspi1.Init.Mode = SPI_MODE_MASTER;
  hspi1.Init.Direction = SPI_DIRECTION_2LINES;
  hspi1.Init.DataSize = SPI_DATASIZE_8BIT;
  hspi1.Init.CLKPolarity = SPI_POLARITY_HIGH;
  hspi1.Init.CLKPhase = SPI_PHASE_1EDGE;
  hspi1.Init.NSS = SPI_NSS_SOFT;
  hspi1.Init.BaudRatePrescaler = SPI_BAUDRATEPRESCALER_64; // 80M/64
  hspi1.Init.FirstBit = SPI_FIRSTBIT_MSB;
  hspi1.Init.TIMode = SPI_TIMODE_DISABLE;
  hspi1.Init.CRCCalculation = SPI_CRCCALCULATION_DISABLE;
  hspi1.Init.CRCPolynomial = 7;
  if (HAL_SPI_Init(&hspi1) != HAL_OK)
  {
    _Error_Handler(__FILE__, __LINE__);
  }
}
然后CLKPolarity  HIGH,LOW都试过, CLKPhase 1,2EDGE也都试过,都没用.

  return ret;
}

以上基本参考的示例程序, 只把发送和接收这里改成了我的库函数.

ADE7878.C就是示例程序一模一样了.

然后我在Main里面函数这样调用的.
  MX_SPI1_Init();
  ADE7878Reset();
  ADE7878SPICfg();
然后最后执行读写寄存器,如下图:
