Week 1: Introduction. This is the first of my video journals. This is for my Design and Tech class at the Art Institute of Pittsburgh Online Division. Hopefully by week 6 it will be down pat:0) …
Typical embedded applications are rather restricted in how they can present data to a user. Limited amounts of data can be displayed on an LCD or a graphical display, but large amounts of data are more problematical. Often, data is transferred via an electrical interface or via electronic storage media, such as a thumb drive, for further examination, but it can be handy to obtain an immediate snapshot of the data. The USB Printer Class driver and host software stack, used on one of Microchip’s microcontrollers with the USB OTG peripheral, allows an embedded application to utilize a USB printer to provide hardcopy output for quick review and possible archival.
AN1142 describes the Mass Storage Class driver for the Microchip USB Embedded Host firmware stack. It explains the basic operations of a Mass Storage Device (MSD) that uses the Bulk Only Transport (BOT), commonly used by USB Flash drives. It also explains the usage of the USB Configuration tool to change the parameters of the Microchip MSD-host driver for the customer?s specific needs.

With the introduction of Microchip?s microcontrollers with the USB OTG peripheral, microcontroller applications can easily support USB embedded host functionality.
