This repository contains NASA's Scheduler Lab (sch_lab), which is a framework component of the Core Flight System.

This lab application is a non-flight packet scheduler application for the cFS Bundle. It is intended to be located in the apps/sch_lab subdirectory of a cFS Mission Tree. The Core Flight System is bundled at https://github.com/nasa/cFS (which includes sch_lab as a submodule), which includes build and execution instructions.

sch_lab is a simple packet scheduler application with a one second resoluton.

To change the list of packets that sch_lab sends out, edit the schedule table located in the platform include file: fsw/platform_inc/sch_lab_sched_tab.h

• Implement Coding Standard in CodeQL workflow
• See #83 and nasa/cFS#270

• Fix infinite loop by making sch_lab exit by making "RunStatus" return ERROR if initialization fails. This causes the CFE_ES_RunLoop function to return false.
• See #82 and nasa/cFS#263

• Removes app registration call, CFE_ES_RegisterApp() since applications do not need to register themselves.
• See #76

• Update sequence count in transmitted messages
• Add Testing Tools to the Security Policy
• See #71

• Aligns messages according to changes in cFE nasa/cFE#1009. Uses the "raw" message cmd/tlm types in definition
• See #59

• Update to use MSG module. Replaces deprecated SB APIs with MSG
• See #58

• Adds header guard (the other warning on the ticket was already resolved)
• See #53

• Reorganize the sch_lab table so it matches the sample_app usage and format.
• See #52

• Fixes schedule table documentation
• Add baseline and build number to version reporting
• See #48

• Apply the CFE_SB_MsgIdToValue() and CFE_SB_ValueToMsgId() routines where compatibility with an integer MsgId is necessary - syslog prints, events, compile-time MID #define values.
• See #41

• Apply the CFE_SB_MsgIdToValue() and CFE_SB_ValueToMsgId() routines where compatibility with an integer MsgId is necessary - syslog prints, events, compile-time MID #define values.
• See #39

• Improved table handling
• sch_lab now builds on Raspbian OS
• Minor updates (see #36)

• Fix for clean build with OMIT_DEPRECATED
• Minor updates (see #35)

• Minor updates (see #28)

• Table definition include update (see #18)

• Minor updates (see #16)

• Minor updates (see #13)
• Not backwards compatible with OSAL 4.2.1
• Released as part of cFE 6.7.0, Apache 2.0

• Released as part of cFE 6.6.0a, Apache 2.0

As a lab application, extensive testing is not performed prior to release and only minimal functionality is included.
