ANSWER

Answered 2022-Apr-17 at 15:02

I am also a little suspicious of the bytes retrieved from wlan_sta.config('mac'). I would have expected something that looked more like b'\xaa\xbb\xcc\x11\x22\x33' instead of b'0\xae\xa4z\xa7$'. The z and the $ seem very out of place for something that should be hexadecimal and it seems too short for what should be six pairs of digits.

You're not getting back a hexadecimal string, you're getting a byte string. So if the MAC address contains the value 7A, then the byte string will contain z (which has ASCII value 122 (hex 7A)).

Am I using the correct method to get the MAC address?

You are!

If it is correct, how can I format it as six pairs of hex digits?

If you want to print the MAC address as a hex string, you can use the ubinascii.hexlify method:

QUESTION

micropython and sys.implementation- different on XIAO SAMD21 and XIAO RP2040

Asked 2022-Mar-27 at 18:05

I was working with micropython on a SEEED XIAO (SAMD21) using version 1.18, and wanted to use 'compiled' libraries (.mpy) to conserve space. I had mpy-cross for version 5 which worked okay for me. I also wanted to have floating point so I built a new micropython with that option- from the latest (20220302) github version- and noticed that mpy-cross had updated to version 6. I thought I would check to see which versions of .mpy were used The micropython documentation suggests some code to check the version of .mpy using the sys.implementation object. I noticed a variety of sys.implementation implementations.

Version 1.18- released by micropython 20220117 on the XIAO SAMD21 gave the following results:

If you want to use precompiled/bytecode .mpy files then you will need to Decide to use either bytecode or compile to native code for your mcu platforms.

For bytecode you will need to distribute a bytecode version that matches the runtime firmware, 1.12-1.18 == 5, next version will increase

For native code you'll need to distribute versions for each platform that you want to support. An esp32c3 cannot run stm32 native code and vice-versa

Also the different ports/board will indeed have differences in some of the stdlib APIs. Your code must be robust enough to handle these differences.

How to send the contents of a variable to Micropython repl

I am trying to create a file in an ESP32 named "PassWord" containing a password, using Micropython Serial.

You could do something like this. Just made this as an exaggerated example so you can learn. You could put this whole thing into the send function input if you wanted.

Change url of a webpage on a local network

Asked 2022-Mar-01 at 08:57

I built a webpage on an ESP32 chip, charged to create an access point allowing my computer to connect in order to access this page.
For the moment I can only access it using the IP of my ESP by typing it in a browser but it can be very bothersome.
I'd like to know if it was possible to change the url of the page using words instead of the ESP's IP.
Maybe I'm missing some technical terms but I didn't find any solution on the internet.

Certainly. The easiest option is enabling mDNS. This allows hosts in the same local network to resolve the device's name (e.g. espressif.local) into its IP. Only works in local network and requires an mDNS client on the computer (Mac, Linux and Windows all tend to have it built in these days).

No idea how to do it in Micropython, though. Give Google a try.

SPDT Switches with a Raspberry Pi Pico

Asked 2022-Feb-23 at 12:37

Basically I'm just trying to figure out how an spdt switch would work with a raspberry pi pico. When I search for information on how to interface a switch with a pico, all I get is info on button switches.

Does the spdt switch act like a closed circuit, constantly providing power to the pin I connect it to?

Assuming the answer to the question above is "yes", how would I go about telling micropython to do different things based on which pin is receiving power?

Sorry for the simple questions, I have no experience in the domain of microcontrollers and can't find this info anywhere.

...

ANSWER

Answered 2022-Feb-23 at 12:37

A switch -- by itself -- doesn't provide power to anything. All it does is close and open a circuit. You can replace the switch with a wire and connect/disconnect the wire and accomplish the same thing.

If you had the middle pin of the switch connected to GPIO 2, and the two outer pins wire to Ground and Vcc, you could use the switch to switch the value of the GPIO between logic 0 and logic 1.

Reading the value would look something like this:

QUESTION

Is it possible to wait for either button A or button B?

Asked 2022-Feb-11 at 15:27

This is code that waits for an event coming from button A.

control.waitForEvent(Button.A, EventBusValue.MICROBIT_EVT_ANY)

I want to wait for either button A OR button B to be pressed.

Is this possible?

EDIT

I know that in Scratch this is possible with something like button.any, also the above code is written in microjavascript, but it is written similarly in micropython, so maybe someone from this field can also help. Thank you.

Have a look at the python code generated using the 'on event from' block in https://makecode.microbit.org. This block can be found under the Advanced tab. The block can be set to wait for either button A or B to be pressed. The micropython code generated in this case is:

your on the right track, os.listdir works just fine on any version of MicroPython, but does not recurse the sub-folders.

so you need to distinguish a folder from a filenode as in the below.

It appears that you are attempting to upip install a CPython module on MicroPython. (sorry , could have seen that sooner)

That will not work - unless that module is packaged specifically for MicroPython.

The error message could be clearer though...

I would suggest searching PyPi for MicroPython specific packages, either through the micropython- prefix or using the programming language filter:

lastly: in upip you can enable some debug messages by setting upip.debug = True as in the below sample
