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 ...
If you want to retrieve data from a specific sensor you can use the grep command.
Windows users: You can download a win32 version of grep from the gnuwin32 webpage. You will also need to grab some additional libraries or you can try this zipped version which should contain all the necessary libraries. Simply extract the zip to your Windows\system32 directory.
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 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>
