Modulation Plugin

2012-04-26T06:35:37Z

59.148.253.117: /* SVN Server */

This project aims to develop an Modulation Plugin Module, to be used in conjunction with a 8/16 bits embedded system such as the dsPic33F development board.

==ToDo==
*Voltage during "Lo" time of DAC can also be set (i.e. not necessary zero)
*modulation cct & PCb
**Bias resistors for op-amp
**crystal & SMD res. too close, easy to short when soldering
**footprint of some chips are too small, enlarge it for easily soldering
**some cct modification
***modify the res. value

==Objectives==
*The modulation module is used to deliver a digital output signal with the following characteristics:
**Square wave
**Variable frequency (0 - >10kHz)
**Variable amplitude (0V - 2.5V)
**Accuracy frequency response (error < 2%)
*Interface to MCU which do the control

==Software Solution==
*Timer Interrupt controlling I2C DAC can only achieve frequency response of about 500Hz
**5byte/cmd
**8bit/byte
**baudrate = 400kHz
**This yields 10kHz (0.1ms)
**As OS context switch is 10ms, set timer to 1ms (1kHz), so that 0.9ms can be used to process other tasks
**timer frequency of 1kHz yields a modulation frequency of 500Hz
*Due to higher freq. response requirement, so using hardware to implement the clock

==Hardware Solution==

===Circuit===

+-----+ +--------+ +--------+
I2C Bus | | | Analog | | Op-Amp |
------------+-----| DAC |------------| Switch |---------| |---------Output
| | | +--------+ +--------+
| +-----+ |

| +--------------+ |
| | Programmable | |
+-----| Clock |-------+

*This architecture allows the square wave to run at a very high frequency, even with a slow I2C and a slow DAC.

===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'' [[Image:3 1 com err.JPG]] 
*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>'' [[Image:3 2 file err.JPG]] 
*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'' [[Image:3 3 rxtx err.JPG]] 
*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'''

===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'' [[Image:3 1 com err.JPG]] 
*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>'' [[Image:3 2 file err.JPG]] 
*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'' [[Image:3 3 rxtx err.JPG]] 
*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'''

Description on how to use dsPicProgrammer to download firmware to [{{SERVER}}/DsPIC30F_5011_Development_Board DsPIC30F 5011 Development Board]

==Loading Bootloader (Once only)==

===Hardware Requirement===
#PC with USB port (with Windows)
#ICD2 Programmer
#Target Board
#5V Power Supply

===Software Requirement===
#[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. See [http://www.sureelectronics.net/pdfs/DB-DP003.pdf manual] for details.

===Hardware Requirement===
#PC (Linux/Windows) with COM Port OR USB-COM converter cable
#Target Board (with bootloader)
#5V Power Supply

===Software Requirement===
#[http://java.sun.com/javase/downloads/index.jsp JAVA JDK or JRE]
#[http://users.frii.com/jarvi/rxtx/download.html RXTX Driver]: Download rxtx-2.1-7-bins-r2.zip or later
#[http://chungyan5.no-ip.org/vc/?root=dspicProgrammer dsPicProgrammer] ('''dsPicProgrammer.jar''')

===Files===
#Application hex file (e.g. '''app.hex''')

===Procedure===

====Setup COM Port====
[[Image:DSC00921.JPG]]
*Connect your USB-COM converter cable to your computer
*Or Using a real COM PORT

[[Image:1.jpg]]
*Go to Control Panel \ Device Manager

[[Image:2.jpg]]
*Find out your Device COM 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], from [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 directory.
::e.g. USB memory devices
[[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 [[Image:2 1 run.JPG]] 
**Enter cmd [[Image: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
::[[Image:5.jpg]]
:*When the program prompt you for an input, press y: [[Image:2 4 prompt.JPG]] 
:*If communication can be established, you should see something like this: [[Image:2 5 progress.JPG]] 
:*Wait until programming is completed. [[Image:2 6 complete.JPG]] 
:*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'' [[Image:3 1 com err.JPG]] 
*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>'' [[Image:3 2 file err.JPG]]

*In case of missing the RXTX driver, you should see the error message: ''Exception in thread “main” java.lang.NoClassDefFoundError: gnu/io/UnsupportedCommOperationException'' [[Image:3 3 rxtx err.JPG]] 
*Solution:
**Copy '''RXTXcomm.jar''' to '''/dsPicProgrammer/rxtx/lib'''
**Copy '''rxtxSerial.dll''' to '''/dsPicProgrammer/rxtx/bin''' (Window)
**Copy '''librxtxSerial.so''' to '''/dsPicProgrammer/rxtx/bin''' (Linux)
