Updated Pico Logic Analyzer Rolls Out with Enhancements
Here's a fresh spin on that article:
Are you ready to dive into the world of DIY logic analyzers? Check out Happy Little Diodes' latest creation, a Pi Pico logic analyzer, designed by none other than El Dr. Gusman. But that's not all! They recently got their hands on the newest version of this design, and it's a game-changer.
The original design could handle 24 channels at 100 MHz, spread across two different PCBs. Just imagine, now it's all on a single board with a whopping 400 MHz operation speed! And guess what? You can even chain several boards together for more channels! The level shifters support 5 V, 3.3 V, or an external voltage, making it ideal for projects like Happy's ZX Spectrum where 5 V conversion is a must.
He's shared his thoughts on the new design in a recent video. The code is available on GitHub, but be warned, version six—the one featured in the video—isn't quite stable yet, so you might need to wait to give it a whirl yourself. The software is impressive with promising prospects for potential integration with Sigrok.
Missed our earlier coverage on this? Don't worry, catch up here. If Sigrok integration is your primary goal, Pico-Coder could be your shining knight!
Here's a quick snapshot of the latest version:
- Based on Raspberry Pi Pico 2 microcontrollers
- Offers a sampling rate of up to 400 MHz
- No support for hardware glitch detection or streaming
- Sigrok integration is not yet confirmed
- Project is currently in active development
- Cost per unit (excluding shipping and initial Pico 2 hardware) is just under €20
Stay tuned for more updates on this amazing DIY project!
This Pi Pico logic analyzer, designed by El Dr. Gusman, not only operates at a faster speed of 400 MHz on a single PCB, but it also numbers among the gadgets that leverage advanced technology, making it a valuable tool for DIY enthusiasts and technology aficionados alike. With its compatibility with various voltage levels and potential for multiple board chaining, it could be an ideal choice for projects in the technology domain, such as Happy's ZX Spectrum.
