I’m trying to read data from ADIS16223 via SPI interface.
But, somehow the received data always read 0x00.
I have checked the signals on oscilloscope which SDO (MOSI) was correct.
But SDI (MISO) stills have no signal sending back from ADIS16223.
I sent the register PROD_ID shown in datasheet (page 9), and tried Manual Mode capture process (page 11). It didn’t work.
I also read this discussion. http://ez.analog.com/thread/36413
But I’m not quite sure how did this solution work?
Manual Mode capture process.
MOSI: 0x9C00 (select manual mode.), 0xBF08 (start the data capture.)
MOSI: 0x1400, 0x0000(dummy), ...
