Current state of SDI12 capabilities?

[rkertesz]

I've been using the stroudcenter SDI12 libraries for communication with a YSI device but I ran into two challenges: (1) it is a little bit fast and loose with no error checking, and (2) it is only compatible with AVR chips. Your project appears more robust (includes master and slave) and generally more structures. Is it compatible with cortex based *inos? Have you tested it with other non-decagon devices? Is it in a state in which I can utilize it?

Hi Ruben,

We have access to a YSI sonde but haven't yet tested with that device. Also
we have only tested using arduino/atmel devices but the code relies on the
platform's hadrware/software serial so it shouldn't be too hard to get
going (we intentionally don't make any low-level calls). This summer we
will be deploying using the codebase with multiple sdi-12 sensors. After
that it should be much more robust but you're welcome to give it a try now.
Feel free to get in touch with me if you have questions.

Thank you for the reply. Quick followup Q regarding hardware vs software serial (vs low level calls). What I ran into was that other implementations of SDI-12 were all built using software serial exclusively. Most 32 bit boards I've seen and used don't support software serial. So, as long as hardware serial is supported without any use of software serial or similar AVR-specific interrupts, then I think this is great. I haven't dug in yet. Also, just an FYI but someone developed a low level sdi12 library for a 32bit chip (https://github.com/duff2013/SDI12_T3) ... actually this is likely very compatible with the chip I'm using in the Konekt Dash.
