Development Environment
- MPLAB IDE > V8.1x
- Microchip C30 compiler > V3.0
- ICD2 or Real-ice programmer connected to PSER1C connected to target board
data collection
SWIFI dataport
- wifi_fast.py -i <ip address or name> [-p <matlab listen port>] -V <variable list filename> -F -f <log file name>
- -i - the IP address of the SWIFI. Typical 192.168.192.xx or "sw8"
- -V specifies the format and names of the packets from the dataport. use : -V imu2.vlist
- -p (optional), default is 9999 - use if multiple plotters running simultaniously. If not 9999, before starting matlab plotter, assign the variable "matlab_listen_port" to some value in the range of 9990 and 9999
- -F (optional) - flush the SWIFI buffer at startup. The buffer could be holding upto ~2 mins of the past data.
- -f the base filename used for logging of the binary packet data, and ASC form of the packets.
- sometimes at power up, SWIFI outputs garbage. The solution is to power cycle the SWIFI until it works.
- this appears to be a baud rate problem - and is being corrected.
- the wifi_fast.py directory is generally something (often \ceb or \cbarn\svn) \pfcmd_python\wifi_v3
- example : wifi_fast.py -F -i sw5 -V imu2.vlist -f ss0103_tuning
matlab
Matlab is used for 'real-time' plotting.
- start matlab
- cd to C:\ceb\0svn\matlab (or the local version of svn://pedant/........./branches/cbarn/matlab)
- optionally set the variable "matlab_listen_port" to something in the 999x range.
- on the laptop generally use plot_laptop
- or on my PC, run the program "plot_float" and bypass the prompts.
