Sensor meta data for BNO080

[Shri1395]

Hi,

I was testing out the nrf52840, and i wanted to initialize the BNO_080 sensor with the nrf52840 DK. Now, i realized that if i want to read from registers to get the quaternion data, i need to create a sensor meta data, and find out the q point for that. Also, i noticed from the datasheet the quaternion data are no longer quat w, x, y, z. They are quat i, j, k,  real. 

It is a bit different than others, because for BNO_055, i needed to specify the register, for example the register addresses for the QUATERNION_REG_LSB, and MSB, and then i could read from the data from it.

It would be helpful if you could provide me with the steps in order to configure the nrf52840 with BNO080 to read the quaternion data.

Hi,

I see you can use either SPI, UART or I2C (TWI). You ca find examples for all these interfaces in the nRF5 SDK, but I haven't seen any code specifically for interfacing with the BNO_080 sensor. I would expect it to be quite simple, though, provided you have the datasheet or a reference driver.
