PEARL Pressure Controller: Jog Buttons Active

[JackEAllen]

As a: developer

I would like to implement the DB logic and update OPI to include an LED to display whether or not the jog buttons are active to reflect the existing functionality present within the LabView VI based on information which will be documented as part of #6763 as the manual does not provide sufficient information to achieve desired functionality.

Acceptance Criteria

What is the acceptance criteria?

• DB logic to control joy buttons active LED
• LED in OPI to display whether or not jog buttons are active
• Raise NotImplementedError in function that calls the PEARL Pressure Controller logic

Extra Information

Why it is needed?
To replicate existing functionality present within the LabView VI

Where required files/links are

• Manual: \\isis\shares\ISIS_Experiment_Controls\Manuals\PEARL Pressure Controller\PEARL handbook_v3_5.docx
• Labview Vi: C:\LabVIEW Modules\Instruments\PEARL\PEARL Pressure Cell Controller
• Please see conversation in PEARL: IOC & OPI for Pressure Controller #6040 to view a screenshot of LabView VI for reference.

Detail on the LabVIEW implementation (part of #6763):
The proto file for the st command covers this, the part of that string related to the jog buttons being active is the 6th section and is true if that part of the returned value from status is not equal to 0 (so $1.F as I read the protocol file)
