Re: Jupyter :: Anaconda :: getting started
I think you can find everything you need to know at https://www.anaconda.com/products/individual When I use Python in my day job it's always in a conda environment and I'd strongly recommend it - there are other ways of creating virtual environments for Python but conda works pretty well in my opini...

Re: BLE Joystick on ESP32
According to this post there's a pull request, basically meaning Jimmo's change is submitted and waiting to be integrated into the code base.

Re: How to use a low-signaling sensor to trigger wake interrupt
It sounds as if your GPIO16 is a push-pull output, so when you had it connected to both the board's RESET and the sensor's output pin, it was actively holding both of those either high or low - this would explain why it actually stopped the sensor working. If you have an input with a pullup to V+, e...

Re: New to micro controllers and MicroPython
I would kind-of recommend the Donald Norris book (listed here ). It's three years old now and doesn't cover the ESP32 specifically, and he can veer off into wordy discussions of language and design philosophies which you won't miss too much by skipping, but the book does cover a good range of practi...

Re: being pythonic ?
You don't usually specify the types of a function's input arguments in Python. As a dynamic language, functions and operators in Python generally adapt to the type of their inputs as far as possible and that's what other programmers would expect your function to do too. What happens if you pass an i...

Re: MicroPython using a Virtual Machine?
If you're going to run it on Windows or Linux, why not create your project in standard Python?

Re: Large color LCD?
I'm very doubtful that any way of doing this will be easier than connecting the display to a Pi Zero and writing a little code to implement some sort of protocol for your MicroPython board to tell the Pi what to display - but then I don't really see why it would make sense to attach a keyboard, mous...

Re: Micropython spectrometer just released!
Many commercial spectrometers have some sort of interface that you can use to acquire data programatically, so it's not quite true that 'all you are left is Excel'. In my last job I needed to build lab equipment to measure chemical and physical properties at low cost, so I might have been interested...

Re: search for an inexpensive device to detect housebreaking
A quick web search for ' glass break sensor ' shows that there are already low-cost products available to do this, either with the sensor and alarm all in one unit or with a sensor that communicates by low-power radio (e.g. 433 MHz) to a central alarm system. What's your objective - to set up your o...

Re: Shift Register PWM
Yes, the transistor solution would look like this: srpwm.png Apologies for the horrible diagram, I was trying out the Digi-key online schematic editor... would not buy again ;) The blue thing is supposed to be your MicroPython board and the pink one is the shift register. The bottom wire, from the t...
