Code Examples

The following applications are provided to demonstrate the typical or interesting usage models of USB Host capabilities.

| Name | Description | | ————————- | ———————- | | CDC Basic | This application uses the USB Host Layer and CDC Client driver to enumerate a standard CDC USB device. The demonstration host application then operates and uses the functionality of the attached CDC Device. | | CDC MSD | This application creates a USB Host that can recognize and enumerate a CDC USB Device and MSC USB Device. | | HID Basic Keyboard | This application creates a USB Host application that uses the USB Host Layer, HID Client driver and HID Keyboard Usage driver to enumerate a USB keyboard and understand keyboard press release events. The keyboard events are displayed using a terminal emulator on a personal computer. | | HID Basic Mouse USART | This application uses the USB Host layer, HID Client driver and HID Mouse Usage driver to enumerate a USB Mouse and detect Mouse button press release events. The Mouse events are displayed using a terminal emulator on a personal computer. | | HUB CDC HID | This application creates a USB Host that can recognize and enumerate a CDC Emulator USB Device and a HID USB Mouse connected via an external Hub. The host will demonstrate the communication from the CDC emulator device and the HID mouse. | | HUB MSD | This application uses USB Host stack and the Harmony Filesystem Service to copy a file from a source USB pen drive to a target USB pen drive. | | MSD Basic | This application demonstrates the use of the MSD Host Class Driver to write a file to a USB Flash drive. The application uses the USB Host_layer , MSD class driver and the MPLAB Harmony File System Framework to enumerate a USB Flash drive and to write a file to it. | | ROOT HUB DUAL MSD | This application demonstrates the use of the root hub of the host.| | Vendor | This application demonstrates how to interface with a USB device using the generic host client driver. The application includes a generic client driver example for a vendor-specific USB device. __
