Overview

Arduino is an open-source physical computing platform based on a simple I/O board and a development environment that implements the Processing/Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Flash, Processing and MaxMSP). The boards can be assembled by hand or purchased preassembled; the open-source IDE can be downloaded for free at https://arduino.cc

Bug reports and technical discussions

To report a bug in the software or to request a simple enhancement go to Github Issues
More complex requests and technical discussion should go on the Arduino Developers mailing list
If you're interested in modifying or extending the Arduino software, we strongly suggest discussing your ideas on the Developers mailing list before starting to work on them. That way you can coordinate with the Arduino Team and others, giving your work a higher chance of being integrated into the official release

Security

If you think you found a vulnerability or other security-related bug in this project, please read our security policy and report the bug to our Security Team 🛡️ Thank you!

Contents of this repository

This repository contains just the code for the Arduino IDE itself. Originally, it also contained the AVR and SAM Arduino core and libraries (i.e. the code that is compiled as part of a sketch and runs on the actual Arduino device), but those have been moved into their own repositories. They are still automatically downloaded as part of the build process and included in built releases, though.

The repositories for these extra parts can be found here:

Non-core specific Libraries are listed under: https://github.com/arduino-libraries/ (and also a few other places, see build/build.xml).
The AVR core can be found at: https://github.com/arduino/ArduinoCore-avr
Other cores are not included by default but installed through the board manager. Their repositories can also be found under https://github.com/arduino/.

Building and testing

Instructions for building the IDE and running unit tests can be found on the wiki:

Updating/Downgrading Arduino-Pico core fails at file extraction
Versions

Arduino IDE: Latest 1.8.19 OS: Windows 11 x64, (ver: Version 10.0.22000.1219), in Oracle VirtualBox from Microsoft Arduino-Pico: 2.6.3 -> 2.6.1

Description

Per https://github.com/earlephilhower/arduino-pico/issues/976.

Users report that when upgrading or downgrading the Arduino-Pico core from 2.6.1 to 2.6.3 (or reverse), updating of the core would fail at the Python interpreter. This leaves the Python interpreter package folder without some crucial files without which it cannot start, and so users get a

Fatal Python error: initfsencoding: unable to load the file system codec ModuleNotFoundError: No module named 'encodings'

when attempting to further compile something.

Reproduction

The steps I used (some may not be needed though):

Install the Arduino IDE from the .zip package for Windows

Install Arduino-Pico's latest version as described

Compile a blink sketch for the Pico. It should compile normally

Close the Arduino IDE

Install Python3 from https://www.python.org/downloads/, tick the checkmark for "Add python to PATH"

Reopen the Arduino IDE

Go to the board manager to downgrade the RP2040 core to 2.6.1

Expected Behavior

The downgrade is done successfully.

Actual behavior

The downgrade fails with

Wire.h signature uint8_t requestFrom(uint8_t, uint8_t); (and others) missing in ArduinoCore-megaavr

Wire.h in ArduinoCore-megaavr for Arduino Nano Every misses signatures which are used in the ArduinoCore

    size_t requestFrom(int, int);

this miss match can throw warnings in libraries using the interface according to the the Arduino-Core - which i consider as "standard" how to do...

example

#include <Wire.h>

void foo()
{
  uint8_t address = 1;
  Wire.requestFrom(address, (uint8_t)1);
}

void setup() {
  Wire.begin();

Trojan:Win32/PackBackdoor ?

I was trying to install Arduino IDE 1.8.19 and as always I ran the installer through VirusTotal. One of the Security Vendor's Analysis detects Trojan:Win32/PackBackdoor.0142b83b. I am thinking that this could mostly be a false alarm? Any thoughts?

Bug? VERY predictable output from random()

VERY predictable output from random(), after being seeded with an incrementing counter.

Attached sketch shows how I'm getting four streams of almost perfectly sequential numbers from an algorithm that uses multiple calls to random() after using an incrementing counter as a seed via randomSeed(). It should not be possible to get anything orderly from that, especially over such an immediately short period.

The sketch (below) produces mac-addresses as my original script does, then has four columns: The first three columns show sequential numbers from the high-byte of the last octet, the fourth column shows sequential numbers from the low-byte of the last octet.

Right from the start, with seed 0xb53fdfdf:

     ba:9e:b0:26:4a:ff    f

That's seeded with 0x3ffe883c, and that output is near the beginning.

The first three columns to the right of the MAC addresses all show the high-byte of the last octet:

The 1st column shows 0xf - 0xf, sequentially
The 2nd column shows 0x4 - 0x4, sequentially
The 3rd column shows 0x9 - 0x9, sequentially

The 4th column counts the low-byte of the last octet over a longer period, but the whole pattern repeats almost perfectly, and seemingly indefinitely, regardless of how it's seeded. Not the behaviour I expect from a PRNG!

Just looking at the "random" MAC addresses I was wanting, it's obvious that the low-byte of the last octet is repeating for 14-15 times (14.7, on average) and then incrementing. Again, should be 100% impossible to get this from any self-respecting PRNG being seeded by a counter.

nb the sketch has a delay() towards the bottom, so it scrolls up on a console at human-readable speed. For data-collection, just comment out the delay.

nb2 the random seed can be set manually.

sketch:

/*
  ===========================================

  buggy "random()" function, as observed here:
  https://github.com/atom-smasher/esp8266_beaconSpam

  this sketch starts with a random seed "randomMacSeed"

  that seeds the prng via "randomSeed()" and an incrementing counter
  
  calls to "random()" are producing some very predictable outputs!

  this sketch shows the mac-addresses as they would be generated,
  and derived from those mac-addresses are four columns, all counting
  incrementally, with very few errors

  expected results: using an incrementing counter to seed the prng, i expect
  to NOT have predictable output like this

  ===========================================
