Hi there,

I bought a P1 cable at sos solutions and was able to read messages using a PiZero using cu. I tried your solution, made sure to install ragel and build-essentials first, cloned the github but then when running make.sh I get the following error:

pi@ZeroW-Black:~/dsmr-p1-parser $ ./make.sh fsm name : parser num states: 576

Any idea how I can continue?

Kr,

Andreas

@lvzon could you please help?

lvzon commented 4 years ago

These are merely compiler warnings, it looks like the application does compile. Does the script create an executable file called p1-test-p1?

InvertedMinor commented 4 years ago

yep

lvzon commented 4 years ago

Well then the program should work. :-) Do note that it's just a test-application though... (This code is mostly meant as a basis for writing your own lightweight applications for reading smart meters in C.)

I'm compiling for FreeBSD. Compiler gets stuck at: ...

Adding -z muldefs to the gcc compiler options in make.sh seems to do the trick. I hope this is the correct way to go ;-)
