BMX160

[amar]

Hi everyone,

Present i am working on BMX160 sensor, As part of reading its ACCL and GYRO data, initially i read its CHIP_ID(0xD8) using SPI Driver.

And i configured its registers like in below attached zip file for reading ACCL and GYRO Data and using below attched files of BMX160 but unable to read its ACCL and GYRO data. 

Plaese help me to come out of this issue.

Note:- Can we read ACCL, GYRO,MAGN Data indipendently?

Thank you,

Regards,

Hello 

The sequence in bmi160_read_sensor_data for accel gyro burst data is as below. 

bmi160_get_sensor_data -> get_accel_gyro_data -> bmi160_get_regs

At this time, you can check bmx160 tries to get data from gyro_x_0_7 to accel_z_8_15. ( Length would be 12)

get_accel_gyro_data function in bmi160.c line 3711. If you change some code, line would be a little bit different. 

Thanks,

Hi,

Yes, i am following the sequence what you are suggested. but i am getting below attached log data of accelerometer.

How do i know whether ACC Config registers are configured proprly or not? by using bmi160 driver code.

Thank you,

Regrd,

Do you have logic analyzer? 

I'd like to check yours from beginning. 

Thanks,

Could you please just share a complete logic analyzer frame? So that anyone can reproduce this for his own project?

I uploaded my SPI log and the code I'm using it. 

Please let me know if you have any questions. 

Thank you.
