This document describes how to migrate from RS232-only applications to RS232/USB applications using Turbo Plus uPSD. Turbo Plus uPSD has two UART ports, one of which is used for the USB-to-Serial Bridge connection. The goal is to implement an easy migration with minimal impact on legacy applications.
This document explains how to migrate legacy RS232 applications to RS232/USB applications using the Turbo Plus uPSD. The solution utilizes the microcontroller's two UART ports, where one is dedicated to the USB-to-Serial Bridge connection.
The guide details the architecture, including loading CDC class drivers for USB on Windows 2000 and XP. It covers the configuration of the USB_UART1 bridge, hardware connections between UART0 and UART1, and the firmware requirements for handling CDC class requests to emulate a virtual COM port.
| Supported Operating Systems | Windows 2000, Windows XP |
|---|---|
| UART Baud Rates | 40.0 KHz oscillator supports 115200, 57600, 28800, 19200, 9600 |
| Maximum Power Consumption | 100 mA |
The UARTs can be configured using Timer2 to operate at 40.0 MHz oscillator speeds with resulting baud rates of 115200, 57600, 28800, 19200, or 9600.
The configuration specifies a maximum power consumption of 100 mA.
The installed driver works with Windows 2000 and Windows XP, though the .inf file must be modified to work with Windows 98/Me.
