USB Host Application with File System and Graphical User Interface

This tutorial shows you step-by-step how to create a complete embedded application. The application uses middleware components to read the contents of a text file from an USB memory stick attached to a development board. After pressing the update button this content is shown on the LCD. The following MDK-Professional middleware components are incorporated:

  • USB Host supporting Mass Storage Class (MSC)
  • File System for FAT devices
  • Graphics for displaying a graphical user interface (GUI) using a touch screen

Various CMSIS-Driver connect the application code and the middleware to the device peripherals:

  • USB for attaching the memory stick
  • SPI for connecting the TFT LCD
  • I2C for controlling the touch interface of the display
