msb-server

The msb-server is a program which interfaces with the MSB via the serial port and handles logging of uwar files and transmission of the sensor data over IPC and other shared memory mechanisms. msb-server was written by Dirk Hähnel of Intel Research Seattle.

usage

    Typical Usage

      msb-server -ini msb.ini

      where msb.ini will typically contain: 

      #Desktops should use the USB device
#SERIAL_DEVICE 			/dev/ttyUSB1
#the iMote2 uses ttyS0 only
SERIAL_DEVICE 			/dev/ttyS0
BAUD_RATE			      921600
HARDWARE_FLOW_CONTROL		0
SOFTWARE_FLOW_CONTROL		0
USE_RTC                       1
SCHEDULE_INTERRUPT_COUNT      5120
SCHEDULE_MIC                 8192
SCHEDULE_ACCELEROMETER        5120
SCHEDULE_AMB_LIGHT            2560
SCHEDULE_BAROMETER              71
SCHEDULE_DALS                   30
SCHEDULE_HUMIDITY               10
SCHEDULE_POWER                   0
MIC_GAIN                        64

LOG_FILE			 test.uwar
LOG_START			 1

    Available Commands

      In addition the msb-server also supports the following switch commands: 
      -ipc-publish-data    publish the converted data via IPC
-ipc-publish-raw     publish the raw sensor data via IPC
-ipc-publish-stream  stream serial data via ipc
-shm-publish-stream  stream serial data via shared memory
-ipc-publish-mic     publish microphone packets
-sync-rtc
-show-rtc
-set-rtc
-use-rtc
-log        specify a file to log data to, see -max-size and -max-time for log rotation settings
-log-type   specify the type of data to log:
  uwar      serial data is stored as packets in a uwar file
  stream    serial data is written directly to a file
-max-size   maximum size of the uwar file before rotating the log file (in kilobytes)
-max-time   maximum time between file rotations

example output

    Typically the msb-server will output something similar to the following. Where the final recieved stats will continue until the program is terminated or an error occurs.
