USIWire issue?

[pawsnizzy]

Hi,
I am intent on implementing this device on my RPi, but am getting the following errors in the Arduino IDE:

`In file included from C:\Users\Dave\Documents\Arduino\libraries\USIWire\src\USI_TWI_Master/USI_TWI_Master.h:76:0,

             from C:\Users\Dave\Documents\Arduino\libraries\USIWire\src\USIWire.cpp:27:

`
Can you suggest where I went wrong - these error messages might as well be in greek:(

Thanks

Hi, To me this looks like multiple libraries/library versions for the USIWire implementation in your library path. Could you check and verify that you have only one library version (and preferably the one that I used i.e., 0.1.0)? The same seems to have happened with your eeprom library... Cheers, Joachim Am 24.

No multiple libaries at all - I've even gone so far as to delete EVERY library except the 2 above - and it's still the same

I have same problem. Arduino 1.8.12. Without Usiwire library I get error about missing library (as expected)

In file included from /Users/adrianmihalko/Downloads/attiny_daemon-master/firmware/ATTinyDaemon/ATTinyDaemon.ino:1:0:
ATTinyDaemon.h:1:10: fatal error: USIWire.h: No such file or directory
 #include <USIWire.h>
          ^~~~~~~~~~~
compilation terminated.
exit status 1
USIWire.h: No such file or directory

Now, I install library as Sketch - Include Library - Add .ZIP Library and I choose USIWire-0.1.0.zip.

I click Very/Compile and I get the same error:

Ok, I'm not sure how this happens, but if you use "Sketch - Include Library - Add .ZIP Library", then the file contains only the following: "../USI_TWI_Slave/usi_io.h". This is clearly wrong and two possible explanations are on the top of my mind:

• The original author uses a symbolic link that is interpreted wrongly by the Arduino IDE when unpacking the files
• The Zip-Archive knows that both files are the same and saves only a reference, which again is interpreted wrongly by the Arduino IDE
  In both case I would see the problem in the Arduino IDE.

Two simple possible fixes:

• Copy the file from the TWI_Slave over to the TWI_Master
• Remove the directory, unpack the library manually and copy it to your libraries folder

I suggest the second way as the general way to install libraries. This ensures that everything that goes wrong comes from your own errors.

Hello, I am the original author of USIWire. Please note that I have released version 0.2.0, which no longer contains symbolic links. It is also back in the Arduino Library Manager.

PS: @jbaumann very amazing project! I had something like this in mind when developing USIWire. I will give it a try!

[adrianmihalko]

Thank you guys, release 0.2.0 solved the issue.
