can you be more specific about what you mean, you can print out the value iwth more digits of precision in arduino?
Hi Ladyada, I am using Python driver on the Raspberry Pi. My output currently is: Gravity (m/s^2): (0.62, -0.42, 9.77) When I try to format the output with five digits it just gives extra zeros: 0.62000 It looks like the number of digits is limited when data is converted from binary to float.
could be - that precision may not be available!
OK, but is it possible to get raw output out in in binary or in dec? If yes than I can convert the the data into needed precision on a higher level using range and offeset data.

thats where the response is read from i2c, so you just have to call bno._read_register(0x28, 6)
to get the raw data from that register
Closing. Looks answered.
Is it possible to increase the accuracy of the reported accelerations to at least 8 digits? It is currently just two digits, however, in a 2G mode 14 bit ADC should have an LSB value of 0.002395019531250m/s^2 and we are loosing information.
