Hardware Requirement

1. PC (Linux/Windows) with COM Port OR USB-COM converter cable
2. Target Board (with bootloader)
3. 5V Power Supply

Software Requirement

1. JAVA JDK or JRE
2. RXTX Driver: Download rxtx-2.1-7-bins-r2.zip or later
3. dsPicProgrammer (dsPicProgrammer.jar)

Files

1. Application hex file (e.g. app.hex)

Procedure

Setup COM Port

• Connect your USB-COM converter cable to your computer
• Or Using a real COM PORT

• Go to Control Panel \ Device Manager

• Find out your Device COM Port Number

Get the Dspic Programmer

• Download dsPic_Programmer.zip, from updated directory or svn server
• Save to a directory.

e.g. desktop

• Unzip the dsPic_Programmer.zip, then you have an unziped file.

---

• Drag the unzip file to a directory.

e.g. USB memory devices

---

• Save your .hex file(foo.hex) to your directory location

e.g. X:\dsPic_Programmer\ ---> X:\ is the driver where the dsPic_Programmer located

Download Firmware

• Start a Command Prompt
  • Start -> Run

  • Enter cmd
    File:2 2 cmd.JPG
    
• Run dsPicProgrammer
  • Make sure your device is connected through a "Direct RS232 Cable" to PC Serial Port.
  • Change to the directory where dsPicProgrammer.jar is located and run the command, for example:
    • Windows
      • jre\bin\java -Djava.library.path=.\rxtx\bin -jar dspicProgrammer.jar COM1 115200 foo.hex or
      • dsPicProgrammer.bat COM1 115200 foo.hex
    • Linux
      • java -Djava.library.path=./rxtx/bin -jar dsPicProgrammer.jar /dev/ttyS0 115200 foo.hex or
      • dsPicProgrammer.sh /dev/ttyS0 115200 foo.hex
  • Legend:

COM1 is your COM Port ID

115200 is communication speed [in bps]

foo.hex is your firmware new file

• When the program prompt you for an input, press y:

• If communication can be established, you should see something like this:
  
  
• Wait until programming is completed.
  
  
• after all completed, power OFF your device, then power ON again, enjoy your new updated.

Troubleshooting

Invalid COM Port

• In case of selecting an invalid COM port, you should see the error message:
  gnu.io.NoSuchPortException: Choosing COM Port Error
  
  
  
• Solution: check the COM port ID, or close any programs that are using the COM Port

Missing firmware file

• In case of selecting a firmware file that does not exist, you should see the error message:
  java.io.FileNotFoundException: foo1.hex <The system cannot find the file specified>
  
  
  
• Solution: check the file path

Missing RXTX driver

• In case of missing the RXTX driver, you should see the error message:
  Exception in thread “main” java.lang.NoClassDefFoundError: gnu/io/UnsupportedCommOperationException
  
  
  
• Solution:
  • Copy RXTXcomm.jar to /dsPicProgrammer/rxtx/lib
  • Copy rxtxSerial.dll to /dsPicProgrammer/rxtx/bin (Window)
  • Copy librxtxSerial.so to /dsPicProgrammer/rxtx/bin (Linux)

Missing JAVA

• In case of missing JAVA JDK or JRE, an error message will be prompted.
• Solution:
  • Copy the contents under directory C:/Program Files/Java/jre$(VERSION)/ to /dsPicProgrammer/jre
