I know most of you guys run the HMC5883l

but recently Ive been getting QMC5883 and MMC5883 Version of the chip

the only issue is MMC5883MA is fairly new and its replacing some of the HMC5883l

I have difficulty understanding data sheets unless there is a use code basis

theres not alot of projects or topics discussing on its addressing and registry on how to use them

plan to implement it to the multiwii 2.4 code just needed help understanding these chips

thanks.

you can personal message me too on how to implement

Which datasheet? I didn't find one in your post.

The HMC5883L was discontinued a couple of years ago and the clones or imitations don't work very well.

Better magnetometer modules are available from Pololu, with working example code.

need help on this one also another recent chip MMC5883MA

https://datasheetspdf.com/datasheet/MMC5883MA.html

#define MAG_ADDRESS
#define MAG_DATA_REGISTER

static void getADC() {
i2c_getSixRawADC(MAG_ADDRESS,MAG_DATA_REGISTER);
MAG_ORIENTATION( ((rawADC[1]<<8) | rawADC[0]) ,
((rawADC[3]<<8) | rawADC[2]) ,
((rawADC[5]<<8) | rawADC[4]) );

this to implement on the Multiwii code sensors

Just an update

I have uploaded my codes here for anyone to check see where the issues is .

I try adding the new sensors manage to get signal but the numbers are way off and fluctuating . if anyone knows on I2c can help me work it out

here is the data sheet to the sensor

thanks
