Add QMC5883P driver

[BortEngineerDude]

User description

This should close #10744
I made this driver looking into the datasheet, and I don't have the QMC5833P device, so testing is mandatory before merging.

compared QMC5883L and QMC5883P on M10Q-5883 board
Maybe we can set the alignment of QMC5883P to be the same as that of QMC5883L.
This way, users will not be confused when setting it up.

PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

⏱️ Estimated effort to review: 3 🔵🔵🔵⚪⚪

⚡ Recommended focus areas for review Typo in Constant Line 63 contains a typo in the constant name QMC5833P_CONF1_MODE_SINGLE which should be QMC5883P_CONF1_MODE_SINGLE to match the chip name pattern used throughout the file. #define QMC5833P_CONF1_MODE_SINGLE 0x02 #define QMC5883P_CONF1_MODE_CONTINUOUS 0x03 Typo in Constant Line 100 contains a typo in the constant name QMC5833P_STATUS_OVFL_MASK which should be QMC5883P_STATUS_OVFL_MASK to match the chip name pattern used throughout the file. #define QMC5833P_STATUS_OVFL_MASK 0x02 Missing Y-axis Reset In the qmc5883pRead function, only X and Z axes are reset to zero on line 132-133, but the Y-axis is not reset. This could leave stale data in magADCRaw[Y] if the read operation fails. mag->magADCRaw[X] = 0; mag->magADCRaw[Z] = 0;

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
Possible issue	✅ Reset all magnetometer axes Suggestion Impact: The suggestion was directly implemented - the missing Y-axis reset line was added exactly as suggested code diff: + mag->magADCRaw[Y] = 0; The Y-axis is not being reset to zero in case of failed read, which could leave stale data. All three axes should be reset to maintain consistency and prevent potential issues with outdated magnetometer readings. src/main/drivers/compass/compass_qmc5883p.c [131-133] // set magData to zero for case of failed read mag->magADCRaw[X] = 0; +mag->magADCRaw[Y] = 0; mag->magADCRaw[Z] = 0; [Suggestion processed] Suggestion importance[1-10]: 8 __ Why: The suggestion correctly identifies a bug where only the X and Z axes are cleared, potentially leaving stale data in the Y axis upon a failed read, which could lead to incorrect sensor fusion.

QMC5883P alignment is same as QMC5883L now.

[sensei-hacker]

It would be great if someone can test this.

im on it, what do you need I have a controller here with the QMC5883P.

[synersignart]

Right now its detecting the Mag but wasnt able to read data off it. I need more info from BortEngineer on this

any update on your end regarding the QMC5883P drivers'?

Manage to confirm it from BortEngineerDude from another independent test of the mag.

[synersignart]

after a few more test we can push this on the next INAV release

[sensei-hacker]

@synersignart
Thanks for doing that testing!

You had said "Right now its detecting the Mag but wasnt able to read data off it"
From your latest message, does that mean this PR is now working properly for you? Based on your testing, this is ready to merge?

[synersignart]

w working properly for you? Based on your testing, this is

its currently working on my flight controller as is now.
and near ready thanks to BortEngineer assistance. whats remain is do we need to mount it on a drone to test it?

excuse for having it ported to the INAV 8.0.1 as I need the configurator to visualize it at the moment

I don't think there is any need for that - just need to check that it correctly reads north, south, and east and west on the bench.

[synersignart]

Ive tested it too with the compass 0-360 readout at setup its showing correctly so far I can reconfirm it again later when I get home

[sensei-hacker]

Thank you very much, all of you!

[synersignart]

so far I can confirm on several bench test that the compass heading is all good 0-N 90-E 180-S 270-W
