I used @pythoncoders fusion lib to work with the lsm9ds1 sensor chip and made a balancing ball example (video link is also in the link above)

Re: ESP8266 HUZZAH breakout + LSM9DS1 9DOF

I'm the author of this driver. It was originally designed to work with the pyb module and its I2C interface. Later I started to port the driver to work with the machine module but unfortunately I couldn't test it because my SenseHat board was broken. It seems that I've overlooked a couple of things....

Re: micropython R1.9 ETA @@ released @@

I guess he meant it was never part of the machine module (pyb still supports high/low)

To me, high/low refers to an electrical state, and that is what a pin's state is. It is somewhat confusing that on/off is now used for both signal and pins... but maybe it's just me...

Re: STM32L467DISC port not working?

It's kind of odd. In mpconfigboard.h, there is MICROPY_HW_SPIFLASH_SIZE_BITS defined (probably to activate the external SPI flash). This in turns activates a compiler switch within storage.c (USE_INTERNAL = 0). So your code snippet shouldn't make a difference on the outcome (since it's not active). ...

Re: SPWF04 - wifi module from ST

lets hope they release their source code so that the module can be upgraded with a more recent uPy version. Without that it is pretty inflexible.

Re: Jupyter notebook kernel from adafruit

I've created a starter jupyter worksheet that explains things (how to install jupyter and the mpy-repl-tool package) and shows how to turn on a LED resp. the example disco flash effect from the official tutorials: https://github.com/hoihu/projects/blob/master/uPy/jupyter/uPy-tutorial1.ipynb It's pre...

Re: SPWF04 - wifi module from ST

On the 1st page of their datasheet they mention uPy as a preprogrammed application. And further reading reveals: The SPWF04Sx includes a MicroPython scripting engine to enable simple and fast custom application development on the module MCU: no external MCU is needed and the customer application run...

Re: Jupyter notebook kernel from adafruit

Really nice.

I'm using jupyter lately quite a bit but it didn't cross my mind that this combination is possible.

Would be cool to have a set of jupyter notebook tutorials, e.g. for uPy workshops.

Re: SPWF04 - wifi module from ST

Despite the odd naming that is interesting. It does offer 2MB flash and wifi at a compelling price but more relevant is that it is coming from one of the major ARM chip manufacturer - and they mention uPy as a key piece of FW. I think that is great! Lets hope other silicon manufacturers (TI, Freesca...
