Signal Endpoint

Interface to digital pins configured to produce square wave signals.

This class is designed to allow for square waves at various frequencies and duty cycles.

Control is defined by specifying the wave period as (T3Time) and the active portion of the cycle as (T2Time).

See the entity overview section of the reference for more detail regarding the timing.

See the Signal Entity for generic information.

PUT /api/v1/brainstem/(serial_num)/signal/(index)/enable

Enable/Disable the signal output.

See JSON Schema for Request Object and Response Object

Parameters:

  • serial_num – Serial Number of device to access. Formatted as a hex string (e.g. “0x1234ABCD’). Optional on embedded REST server.

  • index – Index of entity to access. Default is 0.

Request JSON Object:

  • value (boolean) –

    Boolean value to set.

    May be specified as a boolean, integer, or a string (formatted as “True”, “FALSE”, “1”, etc.)

Response JSON Object:

  • response.value (boolean) – Value formatted as a boolean

  • response.rawValue (integer) – Unformatted value

GET /api/v1/brainstem/(serial_num)/signal/(index)/enable

Get the Enable/Disable of the signal.

See JSON Schema for Response Object

Parameters:

  • serial_num – Serial Number of device to access. Formatted as a hex string (e.g. “0x1234ABCD’). Optional on embedded REST server.

  • index – Index of entity to access. Default is 0.

PUT /api/v1/brainstem/(serial_num)/signal/(index)/invert

Invert the signal output.

Normal mode is High on t0 then low at t2.

Inverted mode is Low at t0 on period start and high at t2.
