| A | Toggle the use of AIRPORT. If AIRPORT is OFF, this turns it ON, if AIRPORT is ON, this turns it OFF. By default AIRPORT is ON the first time EaKiu is run. When ON EaKiu uses the Apple AIRPORT connection to sniff wireless access points. When access points are found they will appear as small green and red arrows above the chart in the corresponding channel locations (red arrows for SECURE and green arrows for OPEN networks). Use the 'a' key to see a list of all networks. |
| a | When using AIRPORT mode, the 'a' key will show a list of all the channels and what networks are on them (if more than one network is on the same channel only one will be shown for that channel). If a channel is no longer a network it grays out but the information is still visible. To return to the main display hit any key. |
| g | Use the 'g' key to switch graphing modes. The first time EaKiu is run it comes up in the LINEAR multi-graph. Click 'g' once and EaKiu will show the 3D Spectrum Graph. Click 'g' again and EaKiu will show the 3D Interactive Quad Graph. Clicking 'g once more will show the 3D Interactive Wireframe Graph. Clicking it again brings you back to the original LINEAR Multi-Graph. |
| G | The 'G' key is identical to the 'g' key with the only difference being that it moves in the opposite direction. |
| h | Shows a brief Help page of interactive and command line options. To return to the main display hit any key. |
| i | Captures the current EaKiu window as an image and saves it in a file in the current directory. The file is named:
YYYYMMDD-HHmmSS.tga
Where 'YYYY' is the year, 'MM' is the month, 'DD' is the day and 'HH' is the hour, 'mm' is the minute and 'SS' is the second. The file is stored as a RGB TGA (.tga) file (Truevision file format). Most image programs can read this format. |
| l | When in either the 3D Interactive Quad Graph or 3D Interactive Wireframe Graph the 'l' key will toggle 3D lighting ON and OFF. The lighting defaults to ON. Lighting can often enhance the readability of the QUAD and WIRE graphs. If you find that lighting interferes with viewing the graph turn it OFF. Note that as of version 3.0 of EaKiu, the status of the light no longer appears on the main window. |
| p | Pauses the current device being viewed in EaKiu. While paused no data is recorded or displayed for the paused device. Hit any key to un-pause. |
| q | This key quits EaKiu and writes the current configuration file out to disk. This is the normal way to exit the program. See also the 'Q' command below. |
| Q | This key quits EaKiu but does NOT write any configuration file to disk. |
| r | This key starts and stops RECORDING mode. When recording EaKiu writes the streaming the devices wi-fi data to a CSV file (comma separated value).
Click 'r' once to start RECORDING and click 'r' again to STOP recording. Each recording will be stored in a file with the name:
YYYYMMDD-HHmmSS-n.csv
Where 'YYYY' is the year, 'MM' is the month, 'DD' is the day and 'HH' is the hour, 'mm' is the minute and 'SS' is the second. 'n' is an incrementing number to avoid duplicate files. |
| R | This key will reset all values that were overridden by the configuration file, thus returning a running program back to initial default conditions. |
| s | Each time you click the 's' key EaKiu will switch between your active data sources. |
| w | Each time you click the 'w' key EaKiu will switch between your active USB (WiSpy) data sources. |
| Z | This key will zero all the data. All arrays (Current, Peak, Maximum, and Average) are all reset to base values. |
| z | This key will zero ONLY the Maximum data - allowing new maximums to be tracked. |
| ( ) | This will slow down '(' or speed up ')' the GL frame rate (frames per second) at which the window is refreshed. The values can span between 10 and 110 and indicate approximate frames per second. If you set the value to 111 it will read "OFF" and frame rate limiting will totally be turned off (meaning that GL will run full-speed). With version 1.4 the FPS defaults to 30 frames per second. Note that this is an approximation only. You can set FPS to a value that may be unreachable due to the current complexity of the display. The system tries to maintain as close to the selected FPS as it can, based on what else is happening in the system. |
| < > | This will decrease '<' or increase '>' the chart depth used for the 3D, and LINEAR averaging views. By default the chart depth is set to 400 rows (where each row has 85 samples). Under normal USB fob usage, this is approximately 6 seconds of data. You can decrease the chart depth to as low as 5, or as high as 5000. Higher values allow you to view more consecutive samples of data (at a slower rate depending on your CPU). |
| { } | This will decrease '{' or increase '}' the flowing average. By default the flowing average is set to 3 consecutive samples. Using these keys you can get the flowing average to range anywhere from a low of 3 to a high of the current chart depth. The higher the value, the more consecutive signals are averaged to produce the average display for the charts. Use this to filter out noise or spikes in the data. |
