The existing "PZEM-004Tv30.h" library is not compatible with my Uno R4 board, apparently because it contains AVR-specific instructions. (Library properties says "architectures=avr,stm32,esp8266,esp32".) I can't find an alternative. Does anyone know of another one, or whether this library will be updated in the foreseeable future? Or even how I might contact the author Jakub Mandula? His github page (mandulaj) says he can be reached by email but doesn't say how.
The usual way is to open an issue on the library's github:
But as far I see, the author do not answer to issues for long time.
Thanks, at least that tells me what I should do - github is all new to me. I'm no C/C++ programmer, so updating it myself is clearly 'beyond my pay grade'.
Oh well, I guess that's the way it is. Fortunately the library works fine for the earlier boards, so I can use it with my Uno R3 and just ship the data off somewhere else to be handled.
