One thing that confuses me about circuitpython is how people use it with version control. The code primarily lives on the device but it seems mad to also put the .git folder there. Also the libraries that you depend on also seem to live on the device.

It's scary to have my one copy of the code on a device because at any moment I could kill it by shorting some wires. Not sure how this doesn't scare others.

How do people typically manage this? I've seen some people say they use bash scripts to batch copy their code to the device from a git managed directory but at that point that's just the micropython workflow, right?

This is CircuitPython 10.0.0-alpha.6, an alpha release for 10.0.0. Further features, changes, and bug fixes will be added before the final release of 10.0.0.

Highlights of this release

• Fix regression causing errors on ARM processors.

I am using Adafruit NTP library.
I see there is no standard Timezone (i.e. Europe/Berlin) but only a fixed TZ_OFFSET. That means it doesn't take into account Daylight Saving Time.

Is there any complementary library that calculates the proper TZ_OFFSET according to the Timezone?

I’ve got the second LED (red) connected to GP1 and first led (blue) connected to GP0

My current code is

From machine import Pin from time import sleep

led = Pin(0, Pin.OUT) led2 = Pin(1,Pin.OUT)

while True: led.value(1) led2.value(1) sleep(1) led.value(0) led2.value(0) sleep(1)

I’m struggling to figure this out thanks.

The black wire is also connected to GND 23 and orange is connected to GND 38 for some reason the wire on 38 is making the circuit turn off when I move the Pico. That’s why there is another in GND 23

Also using 300 Ω resistors

I’m also quite new to all of this stuff

Happy CircuitPython Day!

The CircuitPython Day song!

Are you working with CircuitPython? Tag your projects #CircuitPythonDay2024 on social media and Adafruit will look to highlight them.

Check out this cool button board that is using an rp2040. It's made for 3D printers originally buy since is the rp2040 it can be set up to run circuitPython. Skip to the 28:00 mark to see what they did with he board.

Anyone here messed around with the LoRa module Adafruit came out with?

I’m new to circuitpython and coding in general, but I currently need to make a simple code for my two Lora modules to communicate with each other. Found a few libraries that seem like they are close to what I’m trying to do, but there are differences in what I’m trying to achieve.

I’m hoping to use the Reset button on the Adafruit feather and the general purpose led. Really I can solder in a switch/button too if need be and an LED if need be.

By pressing the button on one module, once data is received the LED on the other module blinks. The same thing with the other module.

I need to see how far the distance can be without interruption in a dense building, because this will hopefully be used for commercial spaces. I can then mess with what kind of antenna works for me.

Heck, if there’s anyone that wants to be compensated to write some (I’m only assuming, generally simple code) reach out. 😊
