Thank you for your feedback, Phil. You’re right, many people are confusing the 2 models and I will add the Q model tutorial as soon as I will get one of these

I also did not initially distinglish between H and Q versions and didn’t get far. Fortunately I did have an old H and your calibration and test programs worked perfectly. I wish you would consider presenting this again with the Q version as well (I have 1 H and 10 Q’s).

Hi Bent. I’m sorry but I don’t have a QMC5883L for tests and I can’t publish a code without testing it. You can try to search on Google (or whatever search engine you prefer) if there’s something about “QMC5883L micropython” and tests these scripts.
Sorry

From comments found it must be a QNC5883, since the I2C address is 0x0D. However, using code examples for the HMC5883 all its data output values are 0. Does anyone know how to solve this.

I bought the HA5883L whic seems to be a QMC5883, cause it’s i2c address is 0x0D. All data outputis 0.
Please le me kow if you found a solution.

I have the exact same issue, except heading is also 0.00. Please let me know if you found a solution.

Thank you for your appreciation. Enjoy your Pico 😉

Well, thats a day I’ll never get back. HaHa
I should have read more carefully. I have a handful of these QMC5883L I bought as HMC5883L. I did find one actual HMC5883L, and using your code and instructions got it working fine. Thankyou vary much for your timely response and your help, much appreciated.

Hi Jim,
as in previous commenti, this address means that your sensor is a QMC5883L. It appears a lor similar to the HMC5883L but they don’t work with the same code. I don’t have a QMC5883L for testing and coding, so you should search on google for tutorials on that specific hardware
