Re: AttributeError: 'function' object has no attribute '__name__

Haha, mostly what I do when answering MicroPython questions on stackoverflow is suggest people come here.

I'm not familiar with defining decorators (I'm sure it's something I should learn) but is this an example of User-defined attributes for functions are not supported?

Re: ESP32 Custom PCB design

Is anything in that document relevant to using a module such as the WROVER? The second "Standalone ESP32 Module" made me wonder if for example I must use a four-layer design. I had hoped to place a WROVER on a two-layer board. The WROVER is a standalone ESP32 module, so that document explains how t...

Re: WIFI problems and wlan.status

These are constants defined by the network module. So if the result of WLAN.status() is equal to network.STAT_GOT_IP you have successfully connected, and so on.

Re: ESP32 Custom PCB design

Do you want to design your own PCB for a bare ESP32 chip? I'm not an expert but I suspect that is in the category of 'if you need to ask, it's probably outside your capabilities'. If you just need to save some space by integrating an ESP32 module with some support circuitry, I think the answer to yo...

Re: Is there a lcd_seg library ?

Do you have a specific LCD in mind, and what board are you running MicroPython on (and how many GPIOs will you have available)?

Re: Calculate percent value

Rounding sometimes gives you more "significant" digits than the stated rounding parameter. Python's round calculates the result of rounding the input to the specified number of decimal places , not significant figures. If you want to round to significant figures there are several methods suggested ...

Re: Micropython Google sheets

It looks as if you should be able to detect the condition on your Google sheet with IFTTT, then you might be able to notify your MicroPython code via some other service?

Re: RFC Hardware Choices

Yes, sounds like a good project and the Pico sounds like a good board. Developing everything on breadboard with logic level voltages first is a good idea. If you aren't already familiar with this, you'll want to learn sooner rather than later how to protect the inputs, outputs and power supply of yo...

Re: if statement short circuiting

Well, MATLAB has short-circuiting and non-short-circuiting versions of the logical operators: x = false && undefined executes without an error, but x = false & undefined fails. (The non-short-circuiting version can operate on array as well as scalar inputs - and it does short-circuit if it's in the ...
