HI, I don't know your french 
.
Actually I ask you how many data bytes the ADIS16223 can retaine before to send with SPI ? So, how many time measurement ?
A rough example: One secon of measurment = (3*16bits + 2*12 bits)*72.9kHz = about 5250 kbits/s or 656 kbytes/s ! If ADIS16223 can't send and measure at the same time, what is its memory capacity ?
Thank you,
Adrien
