How we made the PJON network protocol from scratch

Thanks, that helps.

I had to check quick at a gas station and post this.

For the most part, I took away 27kbps, and it seems the intention is software bit bang.

Sure, it’s not master/slave like LIN, and with an arbitration scheme more like CAN. But, without hardware codec, DMA buffering and interrupts, I feel it’s a lot less useful to me as my embedded projects are already pushing their limits with hardware communication.

Still, while it’s not good for me, I do see utility in a bit bang format for LED, IR, simple RF, etc. This makes sense and seems well thought out.

No worries, for sure the SoftwareBitBang implementation is not designed to stream digital audio or video at high speed but it is handy for many to move few bytes from sensors in a local network that can be built very quickly and at a low cost.

Have a nice Christmas :)
