ADIS16405 communicating with STM32F103CBT6 using SPI

Thanks for your attentation. As the topic says, I have some problem. I have connected ADIS16405 and STM32 just as the datasheet provides except for the DIO1 pin floating. The problem is I can only get 0xFFFF when either reading product ID or ZACCL_OUT.

I have tried to communicate with the method of direct SPI and simulated SPI, but neither works. I can observe useful and right singals from the SCLK pin, the DIN pin and the CS pin, but not the CS pin by oscilloscope.

Here's how I read things using the ST official firmware functions.

int16_t ADIS16405_Read(int16_t RegAddress)


          GPIO_ResetBits(GPIOA, SPI1_NSS);

          while(SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_TXE) == RESET);

          SPI_I2S_SendData(SPI1, RegAddress);


          while(SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_RXNE) == RESET);

          GPIO_SetBits(GPIOA, SPI1_NSS);

          return SPI_I2S_ReceiveData(SPI1);


I have gotten the code of ADuC7026 communicating with ADIS16405 using a simulated way. I tried to adapt it, but it still doesn't work anyway.

This problem seems to have annoyed me for more than a week. Can anybody help me? Any response would be appreciated!
