API Commands

HTTP RESTful APIs

APIs follow general rule of '=' indicates set and no '=' indicates get. The exception is when a get API requires a
value. Set APIs generally return xxx=PASS or xxx=FAIL. Get APIs return either a single value or a JSON object.

Note that frames referenced by sequences need to be loaded first. Similarly, sequences referenced by series
needed to loaded first.

Info

/info

Returns number of HTTP accesses since power up.

/version

Returns firmware name and version.

/PCB

Returns PCB info (id, rev, and mod) in 12 bit in hex format.

/id

Returns processor 96 bit unique factory programmed Device ID in hex format.

/temp

Returns floating point temperature inside processor in degrees C.

Recipe

/frame=

Sets a Frame in active Recipe (JSON format).

/frame

Returns space separated list of Frame names contained in active Recipe.

/sequence=

Sets a Sequence in active Recipe (JSON format).

/sequence

Returns space separated list of Sequence names contained in active Recipe.

/series=

Sets the Series in active Recipe (JSON format).

/series

Returns Series names contained in active Recipe.

/config=

Sets the Config in active Recipe (JSON format).

/config

Returns Series names contained in active Recipe.
