CDC Serial Bridge
This lab demonstrates a bridge between CDC and a serial port (SCI). The CDC-Serial example
emulates a virtual serial port on the PC. The instructions below will guide you to program the
JS16 MCU, install the driver for the virtual serial port and communicate with a true serial port
using the two independent terminal windows.

Open CodeWarrior for Microcontrollers. From the
Windows start menu, you can locate it using the path
“Programs>Freescale CodeWarrior>CW for Microcontroller
V6.2>CodeWarrior IDE.exe.”
From the CodeWarrior startup dialog, click “Start Using
CodeWarrior.”
Open the CDC-Serial example project by pressing “Ctrl”
+ “O” keys simultaneously. Follow C:\Program Files\
MC9S08JS16Demo\JS16_CDC_Serial and select
“JS16_CDC_Serial.mcp” and click “Open.”
Short 1&2, 3&4 of J4 with jumpers.
From the connection manager menu, select “DEMOJM on
USB1” port and click
“Connect (Reset).”
From the Erase and Program Flash menu, click “Yes” to
allow the debugger to mass erase the MCU’s on-chip flash
memory and program it with the new application.
Your computer will automatically recognize the JS16 as a
CDC device and begin the installation. Some interaction is
needed to install the USB driver. When prompted by
the computer to specify a location, select the
“MC9S08JS16CDC.inf” driver located
in C:\Program Files\MC9S08JS16Demo\JS16_CDC_Serial.
When hardware installation is
complete, the JS16 will be recognized as a CDC device with
an assigned virtual COM port.
With the board turned on and both cables
attached between host and board, compile and
program the JS16 MCU with CDC serial example
by clicking the button to launch the debugger.
Click the “Start/Continue (F5)” button in the
debugger to run the application. Close the
debugger.
