Interfacing QMC5883L sensor with NRF52840

[Boopathi]

Hello,I am new to this field.I dont know how to interface QMC5883L Geo-magnetic sensor which is 3-axis magnetic sensor with nrf52840 and read the temperature and axial(x,y,z) readings.

I Initially programmed the sensor with Twi sensor program, but the raw data read was string of 0's. I am not able to sort out from where(register) the 0's are being read. And the QMC5883L sensor is an alternate for the HMC5883L sensor of same purpose.

Get yourself an logic analyzer (for instance https://www.saleae.com/), then you can compare the TWI exchanges with chapter "8.2 I 2C R/W Operation" of the QMC5883L datasheet.
