The world of microcontrollers and embedded systems just got more exciting! Imagine a protocol that simplifies communication to a single data line, and you have PJON. But here's where it gets intriguing: it's not just a concept; it's now a tangible hardware implementation!
PJON, a protocol that has been around for almost a decade, is making waves with its recent hardware incarnation. This protocol, which can connect up to 255 devices, is a software complexity trade-off, requiring frequent bus monitoring. However, a Verilog-written hardware implementation of PJDL, a PJON-based bus, has changed the game. This implementation, shared by Giovanni Blu Mitolo, significantly reduces the software overhead, making it a game-changer for hardware enthusiasts.
The PJDL peripheral, as Giovanni calls it, is a product of the CROC chip project, an educational SoC endeavor. This development is a dream come true for those who admired the simplicity of the DS18B20 sensor's OneWire but wanted a more versatile and hardware-friendly solution. And this is the part most people miss: it's not just about simplifying communication; it's about empowering makers and developers with a robust, open-source tool for their innovative projects.
We've previously witnessed Giovanni's magic with PJON, establishing data links through LEDs. This new hardware implementation is a significant step forward, offering a concrete solution for efficient inter-processor communication. And the best part? It's all open-source, inviting collaboration and innovation.
What's your take on this development? Are you excited about the potential of PJON and its hardware implementation, or do you have reservations about its real-world applications? Share your thoughts and let's spark a discussion on the future of single-wire communication protocols!
