What kind of data unit should I feed to the BSXLite?

[ZhuRan]

hello, I am using BMF055 on Cortex-M4F and I have get the acc, gyro and mag data from the sensor, and now I want to let it work  with BSXLite, but I get some puzzle about the data which I feed to the BSXLite.

I got the acc data is  like  {x = -35, y = -355, z = 4025} with an range of -2g~2g which is as the example code of BMF055(that is right because 4025*0.000244g/LSB=0.9821g=9.8m/s^2), but after I send it to the BSXLite, I get the result as below bsx_get_accrawdata(&acc_raw_data) then the acc_raw_data = {x = -0.248996973, y = -3.562572, z = 38.5945282} , it is same with the acc_cor_data, that is absolutely wrong because this function return the acc value with a unit of m/s^2, why?

another question is about the calib_stat, I perform the calibration as this video https://www.youtube.com/watch?v=Bw0WuAyGsnY ,I then I can get the bmf055_mag_calib_stat value of 3, but the bmf055_acc_calib_stat and bmf055_gyr_calib_stat looks like is always 0(though the video said that the calibration of gyro just need to still the sensor, it not work in my board)

Hi,

I'll check if BSX-Lite support BMF055, because the bsxlite_cortex_m3_m4_m4f\ConfigStings don't have BMF055.

Another suggest about your first question, please refer to BSXlite-integration and try this solution.

thanks.

BMF055 is a package of several sensors so i think i can use BSXLite.

And now I have done the mag and acc calibration(means got the stat of 3), but I am in trouble that I cdont konw how to calibrate the gyroscope, how should I put the sensor?

感谢！
