The link https://community.cypress.com/external-link.jspa?url=http%3A%2F%2Fwww.cypress.com%2Ffile%2F384511%2Fdownload has the zip file with the python api file and psoc creator api files included. jeffr_71
The folder arduino\EZSLib for the Arduino support don't exist in the zipped library file .
The entire folder of the zip file contains the files for the EZSLib;
Just rename the extracted folder name to "EZSLib" from "EZ-Serial_Host_API_Protocol_Library" and then follow the steps in the guide.
The .c, .h, .json, .py files are all in there. (You can remove the cy8ckit-042-psoc4 folder within it if necessary I think)
Folder renamed and copied to Arduino Library link.
Step6; Use the File -> Examples -> EZSLib -> Examples -> EZSLib_generic_demo menu item to open a simple example sketch.
I can't select the example sketch , it seems there is no required files in our EZSLib .
Board: Freesoc2 ( PSOC5LP )
Hmmmm; Weird. It seems like the files for EZSLib were pulled out of the example/zip.
Possibly HimaM_31 has information on getting an arduino example working?
Otherwise, you can try making a support case to see if they can get it resolved.
Could you estimate when all material is updated on the webpage to enable
a error free usage ?
