cfv_1065
Purpose:
Compute air mass flow on a continuous basis per the 1065 standard using inputs from a specification file.
Enter:
cfv_1065 <priority> <process_interval> <spec_file> [+c] [d|v]
Where:
priority Specify the task priority. process_interval Specify the processing interval in milliseconds. spec_file Specify the full path and specification filename. +c Optional. Specify this flag to identify the task as critical to the watchdog . This option is mutually exclusive with the d option. d|v Optional debug flags. Specify:
- d for basic output
- v for verbose diagnostics
Example:
cfv_1065 12 1000 /specs/cfv_spec.214 +c &
The preceding command spawns cfv_1065’in the background at a priority of 12. The computations are performed once every one hundred milliseconds using the specifications in the file /specs/cfv_specs.214. The task is also assigned to be a critical task. As a result, if the task ever stops responding to the watchdog, any test that is running will be aborted.
Notes:
The cfv_1065 task will register its name with the filename (not the full pathname), in this case “cfv_specs.214”. This name can be used by the ‘re-read’ command to request that it update the specifications by reading the specification file again. This feature allows the specifications to be changed “on-the-fly” without slaying and restarting the app.
