tango_utils module
Generic utility functions for working with Tango devices.
- aiv_utils.tango_utils.member(dev)
Return the member part of the device TRL.
For example, if the TRL is “low-mccs/tile/s8-1-tpm01”, then the member part is “s8-1-tpm01”.
- Return type:
- Returns:
the member part of the device TRL.
- aiv_utils.tango_utils.read_all(devs, attr)
Uses GreenMode.Futures to read the same attr on all devs.
- Return type:
- aiv_utils.tango_utils.single_prop(dev, prop_name)
Return the first value of a device property.
Properties are always lists but many properties only expect a single value. This convenience method makes accessing those less verbose.
- Return type:
- aiv_utils.tango_utils.tango_attr_value(dev, attr, default=<object object>)
Like getattr(dev, attr, default), but using item lookup rather than attribute access.
- aiv_utils.tango_utils.wait_for(devs, attr, desired_value, timeout=60.0, quiet=False)
Block until attr of each of devs has a certain value or matches a predicate.
- Parameters:
devs (
DeviceProxy|list[DeviceProxy]) – a DeviceProxy or a list of DeviceProxyattr (
str) – the name of the attribute to wait fordesired_value – an attribute value to wait for, or a custom predicate which may accept either one argument (the value) or two (the value, and the device)
timeout (
float) – maximum time to wait for each device to meet the conditionquiet (
bool) – don’t log anything
- Return type:
- Returns:
None
