Uwar tools

Overview

This document lists the various tools for working with uwar files and related data. An example .uwar file is hosted on this machine that you can use to test with. All outputs on this page are from this file: example.uwar.

uwar_cat

• msp/src/fileio/uwar-cat.c
• linux download
• windows download (does not support shared memory streaming)

uwar_cat is a program to extract data from uwar files and dump them in a human readable format. The output format is something of the form:

SENSORA      TIMESTAMP DATA ...
SENSORB      TIMESTAMP DATA ...
SENSORC      TIMESTAMP DATA ...

usage

uwar_cat <filename>

uwar-info

• msp/src/fileio/uwar-info.c
• linux download
• windows download

uwar_info will display the meta data stored in the uwar file. This information can be useful in determining what streams are inside a uwar file and what settings might be in use, for example you can retrieve the schedule and the calibration data from the sensor boards with this command.

usage

uwar_info <filename>

uwar_msb_dump

• msp/src/fileio/uwar_msb_dump.c (not yet committed to CVS)
• linux download
• windows download

uwar_msb_dump is a program to dump the raw serial packets stored inside the uwar file to a single binary output file. This is useful for debugging problems with the MSB itself and analyzing the packets received by the msb-server.

usage

uwar_msb_dump <input_uwar_filename> <output_binary_file>
