AVR Reverse Engineering Hack Chat

Join us on Wednesday, April 21 at noon Pacific for the AVR Reverse Engineering Hack Chat with Uri Shaked!

We’ve all become familiar with the Arduino ecosystem by now, to the point where it’s almost trivially easy to whip up a quick project that implements almost every aspect of its functionality strictly in code. It’s incredibly useful, but we tend to lose sight of the fact that our Arduino sketches represent a virtual world where the IDE and a vast selection of libraries abstract away a lot of the complexity of what’s going on inside the AVR microcontroller.

While it’s certainly handy to have an environment that lets you stand up a system in a matter of minutes, it’s hardly the end of the story. There’s a lot to be gained by tapping into the power of assembly programming on the AVR, and learning how to read the datasheet and really run the thing. That was the focus of Uri Shaked’s recent well-received HackadayU course on AVR internals, and it’ll form the basis of this Hack Chat. Then again, since Uri is also leading a Raspberry Pi Pico and RP2040 course on HackadayU in a couple of weeks, we may end up talking about that too. Or we may end up chatting about something else entirely! It’s really hard to where this Hack Chat will go, given Uri’s breadth of interests and expertise, but we’re pretty sure of one thing: it won’t be boring. Make sure you log in and join the chat — where it goes is largely up to you.

Our Hack Chats are live community events in the Hack Chat group messaging. This week we’ll be sitting down on Wednesday, April 21 at 12:00 PM Pacific time. If time zones have you tied up, we have a handy time zone converter.

Click that speech bubble to the right, and you’ll be taken directly to the Hack Chat group on You don’t have to wait until Wednesday; join whenever you want and you can see what the community is talking about.

Arduino Announces Board Based On Raspberry Silicon

The Raspberry Pi Pico burst onto the microcontroller scene last month with much fanfare, and is already popping up in projects left, right and center. Notable for its high clock speed and exciting IO features, it’s a breath of fresh air in a market slowly weaning itself onto ARM architectures and away from 8-bit staples. Not one to miss out on a slice of the action, Arduino have announced their own upcoming board based on the Pico’s RP2040 chip.

The board is named the Arduino Nano RP2040 Connect, a moniker that’s not just a mouthful but likely to be confused with existing Arduino Nano products. It sports several differences to the Raspberry Pi Pico, namely packing WiFi, Bluetooth, and an IMU on board which should make developing motion-sensitive and IoT projects easier, particularly in cases where the Pico’s flexible IO could be useful.

Naturally, Arduino IDE integration will be a major plus point that gets many makers on board, and we can imagine there will be swift development of libraries leveraging the RP2040’s PIO subsystem. If you still haven’t gotten the low down on the Raspberry Pi Pico yet, though, never fear – our own [Elliot Williams] can tell you everything you need to know!
