ibex_bluesky_core.devices

ISIS-specific bluesky devices and device-related utilities.

The devices in this module are implemented using the ophyd_async library, which in turn reads or writes to the underlying EPICS PVs to control equipment.

Submodules

block	bluesky devices and utilities for communicating with IBEX blocks.
dae	Low-level bluesky device interface to the DAE.
muon	Muon-specific bluesky devices and utilities.
polarisingdae	Specialised DAE interface for polarisation measurements.
reflectometry	Reflectometry-specific bluesky devices and utilities.
simpledae	High-level bluesky device interface to the DAE for 'typical' measurements.

Members

NoYesChoice	No-Yes enum for an mbbi/mbbo or bi/bo with capitalised "No"/"Yes" options.
compress_and_hex	Compress the inputted string and encode it as hex.
dehex_and_decompress	Decompresses the inputted string, assuming it is in hex encoding.
isis_epics_signal_rw	Make a RW signal with ISIS' PV naming standard.

class ibex_bluesky_core.devices.NoYesChoice(*values)

Bases: StrictEnum

No-Yes enum for an mbbi/mbbo or bi/bo with capitalised “No”/”Yes” options.

ibex_bluesky_core.devices.compress_and_hex(value: str) → bytes

Compress the inputted string and encode it as hex.

Parameters:

value – The string to be compressed

Returns:

A compressed and hexed version of the inputted string

ibex_bluesky_core.devices.dehex_and_decompress(value: bytes) → bytes

Decompresses the inputted string, assuming it is in hex encoding.

Parameters:

value – The string to be decompressed, encoded in hex

Returns:

A decompressed version of the inputted string

ibex_bluesky_core.devices.isis_epics_signal_rw(datatype: type[T], read_pv: str, name: str = '') → SignalRW[T]

Make a RW signal with ISIS’ PV naming standard.

For a PV like IN:INSTNAME:SOME_PARAMETER:

• The read_pv will be set to IN:INSTNAME:SOME_PARAMETER

• The write_pv will be set to IN:INSTNAME:SOME_PARAMETER:SP
