Hello.

In my [developer.mbed.org/compiler](https://developer.mbed.org/compiler) apeared new project BUT have error witch compilation:
Can not open source input file device.h : No such file or directory
If I change target platform from W7500P to W7500 - project sucessfull compiled.
But I have W7500P (no W7500).
Please let me link to working project for W7500P or say - what change need to do witch this project.

Sorry for late reply.
I think this problem would be caused by “old mbed library”
So I recommend updating to the latest mbed library.
Thank you
