USB Host Mass Storage Class (MSC)

Compatibility Lincoln 60, Lincoln 60E

This example application utilizes the USB Host port to access a mass storage device. It reads a file named MSREAD.TXT on a USB jump drive and copies it to a file named MSWRITE.TXT on the same jump drive. The first UART, which is connected to the COM1 on the Lincoln microcontroller board, is configured for 115,200 bits per second, and 8-n-1 mode. When the program is started a message will be printed to the terminal. Please make sure that jumper JP2 is set for host.
