This repository contains NASA's Telemetry Output Lab (to_lab), which is a framework component of the Core Flight System.
This lab application is a non-flight utility to downlink telemetry from the cFS Bundle. It is intended to be located in the apps/to_lab
subdirectory of a cFS Mission Tree. The Core Flight System is bundled at https://github.com/nasa/cFS (which includes to_lab as a submodule), which includes build and execution instructions.
to_lab is a simple telemetry downlink application that sends CCSDS telecommand packets over a UDP/IP port. The UDP port and IP address are specified in the "Enable Telemetry" command. It does not provide a full CCSDS Telecommand stack implementation.
To send telemtry to the "ground" or UDP/IP port, edit the subscription table in the platform include file: fsw/platform_inc/to_lab_sub_table.h. to_lab will subscribe to the packet IDs that are listed in this table and send the telemetry packets it receives to the UDP/IP port.
- TO remains command-able after a "remove all subscriptions" command; the command now only removes all subscriptions to the Tlm_pipe
- See nasa#75
- Aligns messages according to changes in cFE nasa/cFE#1009. Uses the "raw" message cmd/tlm types in definition
- See nasa#70
- Replaces deprecated SB API's with MSG
- See nasa#65
- Update the TLMsockid field to be
osal_id_t
instead of uint32 - Set revision number to 99 to indicate development status in telemetry
- See nasa#59
- Adds header guard to
to_lab_sub_table.h
- See nasa#59
- Remove reference to deprecated
CFE_ES_SHELL_TLM_MID
. - See nasa#58
- Fixes bug where an unset address values caused subscriptions to MsgId 0 over 200 times. Added a
TO_UNUSED
entry at the end of the subscription list and a break in the subscription loop whenTO_UNUSED
found. No more subscriptions on the unused table slots (no MsgId 0 subscriptions). - Corrects return value of
TO_LAB_init()
to beint32
instead ofint
. Declaration now matches definition, and app builds without errors. - Add build number and baseline to version reporting.
- See nasa#53
- Makes the
TO_LAB_Subs
table into a CFE_TBL-managed table. - See nasa#46
- Replace references to
ccsds.h
types with thecfe_sb.h
-provided type. - See nasa#44
- Apply code style
- See nasa#43
- Configure the maximum depth supported by OSAL, rather than a hard coded 64.
- See nasa#39
- 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.
- Deprecates shell tlm subscription
- Changes to documentation
- See nasa#38
-
Use OSAL socket API instead of BSD Sockets
-
Use global namespace to isolate variables

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