good morning
I want a code C for reading and writing of i2c for the HM5883 sensor.
best regards

I doubt you'll get a good answer on this, for several reasons:

1: This is an FPGA group, and yours is an embedded programming question --
at least, doing it in 'C' implies that you'll be running the thing
on a processor.

2: Code like that is highly specific to the processor and the peripheral,
so you'd need to luck out with someone who's done it and can share --
and you didn't say what your processor is.

3: Code like that is also highly specific to the problem to be solved,
unless someone really went all out to make generic code.

4: If you know what you're doing, it usually takes less time to write code
like that than it takes to use someone else's. If you don't know what
you're doing, then someone else's code won't help you.

This sounds harsh, but I think you need to either learn how to do the work
yourself, or you need to hire someone to do it for you -- and if you hire,
given the level of competence implied by your question, you probably want
to hire someone to do the WHOLE project, for reason 4 stated above.

The only halfway point that I can see in this is if you own a business and
want to hire someone to both do the work and teach you, or if you're a
trusted employee and your boss is willing to hire someone to do the work
and teach you (which will cost him more the one time, and less in the
future if you're trainable and loyal).

If you DO decide to do the work, and want help doing it, then try posting
a question on comp.arch.embedded (which you can do via
embeddedrelated.com). Give it a title like "Interfacing to an I2C
Sensor", and a first line like "I need to interface an XXX processor to a
HM5883 YYY (gyro, accel, temperature -- whatever it is) sensor from ZZZ
(i.e. -- what company?). I've never done I2C before and I'm lost". Don't
expect someone to do your work for you -- expect people to helpfully point
your way. If you're polite and humble, someone will help you.
