architecture

pf_arch_overview ; pf_comm_arch ; Pf_sc_arch ; Pf_mc_arch ; Pf_imu_arch ; Pf_defs ; Pf_insects

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.

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.
  • run the program, "plot_float" and bypass the prompts.
