 Bigger Bigger Smaller Smaller Reset Reset
I have Arduino Duemilanove with ATmega328 chip - is 8-bit chip.
I have sensor ADIS16354  (datasheet http://www.analog.com/static/imported-files/data_sheets/ADIS16354.pdf )
has 16-bit output register contents.
On picture is SPI Sequence for Read Commands. (from datasheet)

It is possible to read the data with my Arduino?
If yes so how?
Thanks for advice.

Easy: after you received 8 bits, store the byte and read another 8 bits. If you store the second byte in the right place, you can access the resulting value directly as a 16-bit integer.

How do I know that I store the second bite at the right place?
Would be a simple program / code for example ?
Help anyone?
