Please clarify what working means as im sure that i have sucessfully added libs in apde and so has Jafal.

> Ok. I realized. difficulties arose with both libraries. this hour I will write in detail, I have little experience in installing libraries. Only automatically-zip and manually dfx. but in both cases, the archive must have a “libraries” directory, which must contain the core library files with the .jar extension. The libraries you referenced do not contain this “libraries” directory and there are no .jar files. Don’t know how to install them on APDE. please give instructions.

I just need to take the last step to victory. how did you install the library you specified in APDE? after all, this library lacks the elements necessary for connection, namely: jar files are missing in the “libraries” folder! How did you manage to connect such a library to APDE? You wrote in your post that you did it. Did you convert the library with something, if so, how and with what?

OK. I will definitely try today. I’m still slowly moving forward with the old library on APDE5.2

This is the freshest.  
how to glue them? not .jar files!

installs very well on APDE5.2  
and I was almost able to run it.

as i said hardware problems i cannot help with as i dont have an arduino to test.

ultimately there are a lot of reasons this could fail and im simply not capable of answering why atm.

glv method works I followed the steps and it is success now the library could be use with APDE

@glv  
I managed to establish a connection.  
I used normal APDE5.2 (unmodified) and normal 0.2.0beta library. The manifest and file filter are used normal. the problem was that all together it absolutely didn’t work at 57600. At any other speed it started to work well.

however, the 57600 terminal worked well in a third-party program.
