## Summary
uorb_generator this tool can be used in conjunction with uorb_listener.
Before using the tool, it is necessary to set the CONFIG_LINE_MAX parameter
to a sufficiently long length to ensure that the terminal can accept complete
input data. A recommendation is to set it to 256 or 512.
Incoming data can be printed via uorb_listener or concatenated manually
using format information, but it must be ensured that the string and struct
information are consistent. Topics saved using uorb_listener -f can be pulled
and imported into the simulator for debugging (mount -t hostfs -o fs=/home/xxx/
/data).
Parameter Description:
-f specifies the path to the input playback file. -n specifies the number of
times to playback the data. This option is only effective when -s is enabled.
-r specifies the playback frequency (in HZ, e.g., 5hz, 20hz). This option is
only effective when -s is enabled. -t specifies the topic for playback, with
the option to specify a specific instance value afterward. -s enables playback
of simulated (fake) data, generating struct data from input entered via the
terminal. It will modify the timestamp of the current data to real-time.
Simulated data should be placed at the end of the entire command.
By following these instructions, users can effectively utilize the Generator
debugging tool in conjunction with uorb_listener for system debugging and
verification.
The tool publishes topic data via uorb.
Notice:LINE_MAX must be set to 128 or more.
generator <command> [arguments...]
Commands:
<topics_name> The playback topic name.
[-h ] Listener commands help.
[-f <val> ] File path to be played back(absolute path).
[-n <val> ] Number of playbacks(fake model), default: 1
[-r <val> ] The rate for playing fake data is only valid when parameter
's' is used.
default:10hz.
[-s <val> ] Playback fake data.
[-t <val> ] Playback topic.
e.g.:
sim - sensor_accel0:
uorb_generator -n 100 -r 5 -s -t sensor_accel0
timestamp:23191100,x:0.1,y:9.7,z:0.81,temperature:22.15
sim - sensor_baro0:
uorb_generator -n 100 -r 5 -s -t sensor_baro0
timestamp:23191100,pressure:999.12,temperature:26.34
fies - sensor_accel1
uorb_generator -f /data/uorb/20240823061723/sensor_accel0.csv -t
sensor_accel1
## Testing
e.g.:
1. uorb_generator -f /data/sensor/19700101000003/sensor_accel_uncal0.csv -t
sensor_accel_uncal2
2. uorb_generator -s -r 5 -n 200 -t sensor_accel_uncal2
timestamp:1,x:-2.0,y:3,z:4,temperature:5
