Re: emulating joystick USB-HID
This page isn't about MicroPython but it seems to have information about how to select or generate the necessary descriptor.

Re: ESP32 access via Ipad
I haven't used any of these but if you can spend a little on hardware it looks as if you can get a terminal app that works with Bluetooth Low Energy serial interfaces, then I think you should be able to connect to the ESP32's UART interface. Alternatively Redpark do Lightning to serial cables, and G...

Re: Asking for Advice: Using SciPy Libraries and a MicroPython Board to create a Graphing Calculator
scipy depends on numpy, and numpy hasn't been ported to MicroPython and is unlikely to be due to its resource requirements - this looks like the nearest thing that exists so far. Do you really need scipy though? What functions does your calculator need to have? IMHO the easiest way of realising some...

Re: Measuring battery percentage
Are you trying to measure the SiPy's own supply voltage, or the voltage of a separate battery? What voltage range do you need to measure? I'm not very familiar with the SiPy / ESP32 but based on the ESP32 MicroPython documentation , the full-scale range of the ADC inputs is about 0 - 1 V unless you ...

Re: Season of Docs proposal for MicroPython
This is a great idea - I hope it's successful.
For me the highest priority looks like getting the user documentation for the popular ports into better shape. With luck that would serve as a model for the documentation of other ports.

Re: Any MicroPython books?
There's also https://pythonbooks.org/python-for-microcontrollers-getting-started-with-micropython/ which I have but haven't yet worked through. The author's style is a little idiosyncratic but the book seems to cover a fair amount, although it may not be completely up to date any more. And if you're...

Re: Developing PCB layout
If you're simply dealing with pull-up or pull-down resistors and decoupling capacitors, then you can almost certainly vary the value by a factor of two or more each way without problems. The only exceptions might be where the resistors are terminating a long or high-speed communication bus, or when ...

Re: datetime and strftime
Methods #1 ('old-style string formatting') and #2 ('new-style string formatting') described in this guide can be used in MicroPython.
Methods #3 ('String Interpolation / f-Strings') and #4 ('Template Strings') can't.

Re: Sensing sound from a speaker
You could connect the LED side of an optocoupler like a 4N35 to those pads on the doorbell, then you have an electrically isolated open-collector output that's easy to interface to a pin on the ESP side. Or if isolation isn't important you can just connect a suitable resistor across them and detect ...
