SH7285/SH7286 USB Function Module

USB to Serial Conversion Application Note

3. USB to Serial Conversion System Using the USB Function Module

3.1 Overview

The sample program converts USB to serial using the USB function module and the serial communication interface

embedded in the SH7285 MCU. To transfer keyboard-input characters, text files, or binary files, activate the terminal

software both on the USB host (a computer in this case), and on the serial device. For example, some characters are

input using the keyboard of the USB host, and the characters are transferred to the serially connected device. On the

other hand, some characters are input using keyboard of the serially connected device for transfer to the USB host.

A system configuration of the USB to serial conversion is shown in

Figure 3.1, and Table 3.1 lists its specifications.
