Getting data from ADIS16470AMLZ

Question

Hi all, 
 I'm just starting in the embedded field and i need some help to reading the data from the ADIS16470AMLZ device to a Linux system. 
 Is there any example program to read and process these data? 
 
 Can someone point me in the right direction? Any help will be appreciated. 
 
 Regards,

Here is a sample python program to read data from the senosr 
 
 import spidev import time 
 spi = spidev.SpiDev() spi.open(0, 0) spi.max_speed_hz = 100000 spi.mode = 0b11 spi.lsbfirst = False 
 def read_x_gyro_out(): return convert_deci_to_deg_per_sec(read_signed_decimal(0x07)) 
 def read_y_gyro_out(): return convert_deci_to_deg_per_sec(read_signed_decimal(0x0B)) 
 def read_z_gyro_out(): return convert_deci_to_deg_per_sec(read_signed_decimal(0x0F)) 
 def read_signed_decimal(address): decimal_list = spi.xfer([address, 0x00]) if decimal_list is None or len(decimal_list) != 2: raise RuntimeError('Did not read expected number of bytes from device!') 
 hex_list = [hex(x) for x in decimal_list] 
 hex_int_1 = int(hex_list[0], 16) hex_int_2 = int(hex_list[1], 16) 
 hex_16_bit = (hex_int_1 << 8 | hex_int_2) binary_string = bin(hex_16_bit)[2:].zfill(16) 
 # Check if the binary number is negative (starts with 1) if binary_string[0] == '1': # Convert the binary number to an unsigned integer unsigned_decimal = int(binary_string, 2) # Subtract 65536 from the unsigned integer to get the signed decimal signed_decimal = unsigned_decimal - 65536 
 return signed_decimal # If the binary number is not negative (starts with 0), simply convert it to an integer else: return int(binary_string, 2) 
 def convert_deci_to_deg_per_sec(deci): return str((deci/10)) + ' deg/sec' 
 while(True): print('x_gyro_out: ' + read_x_gyro_out()) print('y_gyro_out: ' + read_y_gyro_out()) print('z_gyro_out: ' + read_z_gyro_out()) print('================================') time.sleep(0.5)
