Mine actually does support both hard and soft iron bias correction. The class methods to calculate those values are not included yet though. Been pondering about the best way to do it. I did my version mostly for two reason. It was a nice exercise to learn Python. I also have a bit different program...

Do you want to compile an additional c library to the MicroPython intepreter itself, or do you want to use a third party library written in MicroPython with a MicroPython project?

Open separate thread about individual projects.

My existing driver uses soft I2C which is not supported here # Standard port i2c = I2C(-1, scl=scl_pin, sda=sda_pin) # Loboris port doesn't support soft I2C i2c = I2C(scl=scl_pin, sda=sda_pin) A programmatic means of determining the port would be generally useful as there are inevitable differences...

I'm trying to write a portable driver and there is a minor difference in I2C initialisation between the standard port and yours.

What is the difference?

Makes sense, thanks. Guess I need to purchase some other boards than ESP32 for development to make sure code is portable.

I am bit confused about heap and interrupt handlers. Documentation says in several places that ISR cannot allocate memory from heap. For example: ISR’s cannot create instances of Python objects. This is because MicroPython needs to allocate memory for the object from a store of free memory block cal...

Thank you, the heap size option fixed it. So much RAM

I hope we get this also in vanilla MicroPython

One of the reason I am actually considering CircuitPython over MicroPython for a project is the unified API between boards. That and ATSAMD support. I would however prefer the vanilla MicroPython API.

I2C module, which was based on Pycom code (GPL licensed), is now rewritten from scratch (by the way, it now includes i2c slave and some improvements) and is MIT licensed. The update will be commited later today. Awesome! I was looking forward for the I2C slave. Is it also committed to GitHub? I cou...
