For a microcontroller to interface with and control a USB peripheral, i.e., USB printer, the microcontroller must be able to configure its interface as a OTG/Embedded Host USB Interface via a USB Protocol Stack with supports a OTG/Embedded Host configuration.

It should be noted that both the OTG and the Embedded Host USB configuration offer only a limited subset of the USB Host Interface features in comparsion with a USB Host Interface found on a PC or Laptop for example.

Of course, typically the more elaborate the offered features, the more device resources are required, e.g., Flash and RAM memory, to successfully implement the design.

Utilizing either the PIC24 or PIC32 such a design is definitely doable, however it is doubtful that most PIC18s can provided the required resources to implement a USB Host interface and still leave enough to store and execute a worthwhile embedded application.




The following documents and example projects discuss and demonstrate implementing a OTG or Embedded Host USB Interface:
