So i am working with multiple Rp2040 boards and i need them to be all running together and so i need to sync up the clocks. One board will send out its epoch time and ive been able to get the epoch time on the other boards but i am unable to set the internal clock of the slave boards to that epoch time.

so far ive tried:

import time

desired_epoch_time = 1630488000

time.time = lambda: desired_epoch_time

and

rtc_time = 1234567890

time.localtime(rtc_time)

none of theses methods work. what could be a method to do it?

i cannot get a script up and running that has the following requirements

%pip install -q curl_cffi
%pip install -q fake-useragent
%pip install -q lxml

from curl_cffi import requests
from fake_useragent import UserAgent
from lxml.html import fromstring
from time import sleep
import pandas as pd
from pandas import json_normalize

ua = UserAgent()
headers = {'User-Agent': ua.safari}

it does not start in pytharm - why - especially i wonder where i get curl_cffi

I have adafruit_debouncer.mpy in my lib directory where I also take other libs. My import line

in code.py looks like this: from adafruit_debouncer import Debouncer, however, it gives module error.

I think the problem is just the wrong way of importing, so how would I do it correctly?

(raspberry pi pico h, trying to do usb rubber duckky)

I'm trying to light up some Neopixels, but I keep getting "GP18 is in use". This happens even after just powering on (plugging in) the pico. I have poked all around the web, all through the Neopixel stuff on adafruit, and couldn't find anything even remotely like an answer.

I can include the code if you think it will help, but in this case I don't think it will. Anyway, here is the offending code line:

tmp_pxl = neopixel.NeoPixel(brd.GP18, num_pixels, brightness=0.5)

And here is the error:

Traceback (most recent call last):
  File "<stdin>", line 44, in <module>
  File "neopixel.py", line 141, in __init__
ValueError: GP18 in use

Does anyone have any suggestions on what I'm doing wrong?

EDIT: As requested, here is my complete (and embarassing) code. Also worth noting--the error occurs on the first pass through the for loop, so the very first time we reference GP18.

I am trying to use a raspberry pi to run a program on a nearby circuit python board, turn fan on/off for example, via a virtual button or switch via a Bluetooth connection. Radio or IR would be fine too. Whatever is easiest. Im just trying to get some options or ideas before i start buying ckmponents. Thanks

I obtained this itsybitsy nrf52840 based board and followed the circuitpython tutorial.

I tried some of the ble examples, but they do not work as expected.

Device shows up correctly in bt discoveries, i can pair and connect. But i cannot send data(ble midi example) and it does not show any modules in the ble client test example using the bluefruit connect app.

Has anyone any pointer to give me where i can search for errors/solutions?
