Re: Little wonders need some thanks

I can only chime in.

I've been using MicroPython both privately and professionally for more than three years now and it makes embedded work so much more fun...

Thanks a lot!

Re: Project Help Pool Motor

Solid state relays don't provide safety isolation
just wondering. afaik the isolation barrier of an opto isolated ssr is sufficient for safety isolation

Re: How can I use Webrepl for ESP32?

@goatchurch if you use jupyther you may also check this notebook: https://github.com/hoihu/projects/blob/master/uPy/jupyter/uPy-tutorial1.ipynb (note you will need to view it in desktop mode - it isn‘t rendered on mobile devices) it uses an extension of the adafruit jupyther kernel made by @zsquarep...

Re: MicroPython running "bare metal" in the browser via unicorn.js

Just saw that the link has been updated with examples to select/test virtual LEDs, Servos and ADC in the browser.

Awesome.

Re: SenseHAT with PyBoard

Just for the sake of completness: I thought I could use the frambuf module for the 8x8 LED display. But no luck - each pixel occupies 3 byte of color data (24 bit RGB mapping) and that is apparently not yet supported by the framebuf module. Would that be a useful addition? I guess there must be othe...

Re: SenseHAT with PyBoard

I updated this with a fritzing wiring diagram: https://github.com/hoihu/projects/blob/master/raspi-hat/sensehat-pyboard_bb.png 5 wires are necessary to connect a SenseHAT to a pyboard. I updated the hts221 and lps25 drivers to work with the machine API and tried to make them as compatible as possibl...

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...
