Open Source Framework for USB Generic HID devices based on the PIC18F and Windows

Open Source Framework for USB Generic HID devices based on the PIC18F and Windows

Introduction If you’ve dabbled with PIC18F microcontrollers and the USB Generic HID standard before (perhaps you’ve even tried my Building a PIC18F USB device project) then you will have noticed that there is a lot of complexity in supporting USB on both the PIC18F and the Windows host-side of things. Getting beyond the basic steps of
