Editing Programming the Device

==Requirements==

===Hardware===
#PC with COM port (Windows XP Installed for MPLAB)
#ICD2 Programmer
#Target Board
#5V Power Supply

===Software===
#[http://ww1.microchip.com/downloads/en/DeviceDoc/MP750.zip MPLAB IDE v7.50]: v7.60 is not compatible with our current [http://www.sure-electronics.com/ ICD2 Programmers]. There are consistent "Devices cannot be founded" warnings.

===Files===
#[http://chungyan5.no-ip.org/websvn/listing.php dsPicBootloader] ('''bl_5011.hex'''). Original assembly code by ingenia can be downloaded from [http://www.ingenia-cat.com/download/iBL.s here].
#Application hex file (e.g. '''app.hex''')

*If you have not connected and powered up the target, you might see Warnings on invalid device IDs, and/or running self tests.
*See results of self test if necessary: Programmer>Settings, Status Tab. Refer to [http://ww1.microchip.com/downloads/en/DeviceDoc/51331B.pdf ICD2 User's Guide] Chapter 7.

==Hardware Setting==
[[Image:DSC00921.JPG]]
*Connect your usb to rs232 cable to your computer
*Or Using a real RS232 Port -- COM PORT

==Download and Loading Firmware==

===Make sure the RS232 Port in your computer===
[[Image:1.jpg]]
*Go to Control Panel \ Device Manager

[[Image:2.jpg]]
*Find out your Device comm port Number

===Get the Dspic Programmer===
*Download [http://chungyan5.no-ip.org/open_data/electronic_computer/platforms/dspic/dsPicProgrammer/dsPicProgrammer1.5.5.zip dsPic_Programmer.zip], [http://chungyan5.no-ip.org/open_data/electronic_computer/platforms/dspic/dsPicProgrammer/ws/ updated directory] or [http://chungyan5.no-ip.org/vc svn server]
*Save to a directory.
::e.g. desktop
*Unzip the dsPic_Programmer.zip, then you have an unziped file.
[[Image:prog_guid_dl.JPG]]

----

*Drag the unzip file to a director.
::eg. USB memory devics
[[Image:prog_guid_drag.JPG]]

----

*Save your .hex file(foo.hex) to your directory location  
::e.g. X:\dsPic_Programmer\ ---> X:\ is the driver where the dsPic_Programmer located
[[Image:prog_guid_hex.JPG]]

===Download Firmware===
*Start a Command Prompt
**Start -> Run<br>[[Image:2 1 run.JPG]]<br>
**Enter cmd<br>[[Image:2 2 cmd.JPG]]<br>
*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, '''jre\bin\java -Djava.library.path=.\rxtx\bin -jar dspicProgrammer.jar COM1 115200 foo.hex'''
***Or directly using '''dsPicProgrammer.bat COM1 115200 foo.hex'''(Windows)
***'''jre\bin\java -jar dsPicProgrammer.jar /dev/ttyS0 115200 foo.hex''' (Linux)
:::where COM1 is your COM Port ID
:::115200 is communication speed [in bps]
:::foo.hex is your firmware new file
::[[Image:5.jpg]]
:*When the program prompt you for an input, press y:<br>[[Image:2 4 prompt.JPG]]<br>
:*If communication can be established, you should see something like this:<br>[[Image:2 5 progress.JPG]]<br>
:*Wait until programming is completed.<br>[[Image:2 6 complete.JPG]]<br>
:*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:<br>gnu.io.NoSuchPortException: Choosing COM Port Error<br>[[Image:3 1 com err.JPG]]<br><br>
===Missing firmware file===
*In case of selecting a firmware file that does not exist, you should see the error message:<br>java.io.FileNotFoundException: foo1.hex <The system cannot find the file specified><br>[[Image:3 2 file err.JPG]]<br><br>
===Missing RXTX driver===
*In case of missing the RXTX driver, you should see the error message:<br>Exception in thread “main” java.lang.NoClassDefFoundError: gnu/io/UnsupportedCommOperationException<br>[[Image:3 3 rxtx err.JPG]]<br><br>
