MicroPython Port

[dbrgn]

Would be great.

[thijstriemstra]

why.. what is micropython?

[dbrgn]

A Python interpreter that runs on microcontrollers: https://micropython.org/

@dbrgn is there already any progress on this? I need to control a HD44780 with PCF8574 with my LoPy.
Im thinking about working on this. However, I need something to have it working by next Monday :)

[dbrgn]

No, but it shouldn't be too hard, since the I2C functionality is already in there.

You could copy RPLCD/i2c.py to RPLCD/micropython.py to get started. Common code could be moved into a common_i2c file, but I don't think there's actually enough code in the i2c module for this to be worthwhile.

Ok, what are other critical parts?

• I2C: is very straightforward in MicroPython, not a lot to do there
• future: Just saw that there is a port https://github.com/micropython/micropython-lib/blob/master/__future__/__future__.py
• Context managers: https://github.com/micropython/micropython-lib/tree/master/contextlib

I guess I start working on this Thursday.

[dbrgn]

The context managers are deprecated anyways, so maybe you can avoid support for them in the first place?

I'm currently working on a custom codec, but the codecs module is probably supported by MicroPython as well.

Hi, any progress on this? I'd be willing to contribute too if the work can be split, just let me know

[dbrgn]

@melbow Not yet. Feel free to give it a stab, I haven't found the time to do so yet in the last few weeks.

In case you have trouble with the enums, I think these could also be removed from RPLCD since they don't provide that much benefit but make porting harder.
