Hello,
i am using ardiono 1.8.19 and the RX8010SJ library >> https://docs.arduino.cc/libraries/rx8010sj/#Releases
when i compile an example for the arduino "FrequencyOutput" i get the following errors:

Erreur de compilation pour la carte Arduino Uno

What is the problem?
Thanks for your help

The problem is that the library is 5 years old and either a) the Wire library has been altered in that time in such a way that requires the RX8010SJ library to be updated or b) the compiler had been updated is now checking something much more rigorously now than it did 5 years ago and the RX8010SJ library has to be updated.

Whichever it is, the solution is to bring the RX8010SJ library up to date with the compiler's expectactions and/or the Wire library's needs.

Also... what on earth is main.cpp, with its own setup and loop doing in the src subdirectory of the library??? Has anyone ever even tried to use this thing?

Apparently, this file is an example of use that accidentally got into the library code, for practical use it should be removed...

It seems that for all five years not a single real user has tried to compile the library in Arduino IDE :slight_smile:
Created an issue on GitHub.

Try to remove a main.cpp file from the src folder of the library and compile again.

Bravo !! by deleting main.cpp the problem is solved
Thanks for your precious help !

Please mark the topic as "solved"

Just to inform if anyone encounters the RX8010 library problem, after deleting main.cpp visibly in the logs it has problems with the RX8010SJ-0.1.0 library, however the compilation arrives until the end with this error.

RX8010SJ.cpp: In member function 'byte RX8010SJ::Adapter::readFromModule(byte)':

Which was already addressed back in post #2.
