error trying to compile spi2par2019.ino

[Johny white]

Got an open xenium board which I wanted to add LCD with when installing, already ordered daughter board for spi2par2019 and on its way through UPS. While waiting for this, I thought I'd compile and upload spi2par2019.ino to the Arduino Pro Micro Leonardo board I got but getting the following error towards the end of the compilation.

Do you have the src subfolder with all its content from the spi2par2019 github repository in the sketch folder when trying to compile spi2par2019.ino?

I believe that folder includes the code to use the Wire library. 

When I compiled spi2par2019, I received a few different errors than you but they did not prevent the sketch from compiling:

C:\Users\KaosEngineer\Documents\Arduino\spi2par2019\src\SMWire\utility\twi.c: In function '__vector_36':
C:\Users\KaosEngineer\Documents\Arduino\spi2par2019\src\SMWire\utility\twi.c:541:1: warning: useless type name in empty declaration
 extern unsigned char ;
 ^~~~~~
Sketch uses 11188 bytes (39%) of program storage space. Maximum is 28672 bytes.
Global variables use 1061 bytes (41%) of dynamic memory, leaving 1499 bytes for local variables. Maximum is 2560 bytes.

All of the highlighted files and folders need to be present from the repository in the location you load the spi2par2019.ino file from:

The src folder contains the code to use the Wire function(s).

May be I'm just been blind, is there a download link for the whole repositery? Everytime it gave me a different error, I copied the text of the missing file, pasted into note pad and created it but I cannot find a download for the whole files needed in one place!!!

Click on the green box called code the you can download the whole lot as a zip file

Soft modding is like masturbating, It gets the job done but it's nothing like the real thing.

Click the Code button to display the dropdown menu.  Next, click on Download ZIP.  This action will download all of the files in the spi2par2019 repository in a ZIP archive file for the selected branch.  For this repository, there's only one branch - named master.  The zip archive will be named <repository name>-<branch name>.zip -> spi2par2019-master.zip.

I see you beat me to it.  I had not read your post before I replied. So, the answer is posted twice.

Thanks guys, downloaded this and ran it again, this time its giving me less and different errors but its saying its compiled. Is that good to go and upload or I'm still doing something wrong?

Those are the same warnings that I saw.  I believe the code has been compiled and is ready to be uploaded to the Arduino Leonardo.

 

Edit: I opened the Arduino IDE again and recompiled the code.  This time those error lines did not appear.  Weird...

Very odd indeed, I moved the sketch folder up one level. Open and recompiled few times, at first it gave the same error but now it's not giving it anymore.
