Edit

PIC32 tools setup

Install software

• Install MPLAB IDE and other Microchip tools
  • for dsPIC33 and PIC24 : C30 C compiler V2.05 and then license, then install the C compiler V3.23
  • for PIC32, install C32 compiler

• Install python 2.6.4 and support modules Python2.6 32 bit version (Python 2.5.4 or 2.7.x may also work)

• Install development support tools (SVN client, win merge, grep, Baregrep, Visual Studio for IDE, editor, etc.) Dev support
• checkout source code and support scripts from SVN server (user biomech, password:biomechXXX where XXX is the primary lab room number)
• Top level tools
• Install drivers for FTDI CHIP FT2232H [1]

config

mplab IDE config

• This IDE can be used to both edit and compile/build/program

To load a PF project, the default settings of the MPLAB IDE need to be changed:

1. open "MPLAB IDE"
2. Under Configure -> Settings select the "projects" tab
3. Uncheck the "use one-to-one project-workspace model"

Some other suggested changes:

• From the "other" tab, select "automatically reload"
• From the "workspace" tab, select "no", "reload last workspace", and "always show full path"

Some programmer settings could also be changedLLLLL9

• Select Programmer -> settings and then "Program after successful build"

After this works, try to open and compile a workspace/project.

1. From MPLAB IDE, select "File, Open Workspace"
2. Navigate to "trunk/StateController" and open "sc_workspace_mit.mcw" (or similar)
3. Ignore complaint about files having been relocated.
4. after it opens, press "Ctrl F10" to do a "make clean" followed by "make all"

python config

A file that describes the directory structure of the project needs to be placed in c:\

• Edit the file "support_scripts\python_paths.py", so that variables point the root of your project tree.
• The root of your project tree the directory that contains the directories "support_scripts" and "pf_python"
• the string "c:\ceb\0svn" is replaced with your root.
• Afterward, copy it to c:\

The python interpreter needs to be added to the system path:

• Ctrl click "My Computer" and then select "Properties"
• From the new object, select the "Advanced" tab
• Select "Environment Variables"
• To the "PATH" variable, append "c:\python25;"
  • The path variable may exist under "user variable" or "system variables"
• Verify that python is in the system path by starting a DOS prompt and running python

connect to the target (Pic32 or robot)

All the tools below live in the directory "support_scripts". Open a command shell and CD to that directory. Python is needed to run them and should be in your path.

wifi_fast.py

wifi_fast.py is the primary utility for receiving real-time telemetry from the target. It makes connection to the target via either a standard RS-232 serial port, or via a TCP connection. Once connected it reads telemetry, can log the data to a file, and can send the data via UDP for real-time plotting. It also sends keyboard characters to the target which can then be read via the C function 'getchar'.

• get help with wifi_fast.py -h

via a wired connection

via a wireless connection

• Make sure you make a coonection with the [access point http://bmech4.media.mit.edu]
  • also ping bmech4.media.mit.edu

From the support scripts folder run :

• FOR S3 : wifi_fast.py -i 216 -F -f xx -V dataport
• FOR S5 : wifi_fast.py -i 218 -F -f xx -V dataport

do_command.py

do_command.py is used to send 'special' commands to the robot.

do_command.py -h

robo_config.py

robo_config.py is used to read / write the robot's EEPROM and to read some the data structures in RAM.

robo_config.py -h

other tools

dataport

• in the SC file "dataport.c" there is the statement : switch(sc_dp.dataport_select)
  • for each case, there are a number of assignment of robot variables to variables of the form "pf[n]".
  • the special command "157" is used to set the value of the variable "sc_dp.dataport_select"
  • thus the command "do_command.py -i IP_ADDRESS -s 157 1" sets dataport select to 1.
