GUI controllers¶

The files in pyhard2.ctrlr initialize and launch the GUI controllers.

In order to remain compatible with the Dashboard, they must contain a function named createController() that returns the initialized Controller.

The initialization itself may be driven on the command line with the help of the ArgumentParser setup in Config() or in the configuration file passed to Config().

See also:

The format for the configuration file and the command line arguments is describe in Config().

Example:

The skeleton for the createController() function follows:

import pyhard2.ctrlr as ctrlr
import pyhard2.driver as drv
from pyhard2.driver.MODULE import Driver  # import the actual driver
import pyhard2.driver.virtual as virtual

def createController():
   """Initialize controller."""
   config = ctrlr.Config("NAME")  # name of the driver module
   if config.virtual:
      driver = virtual.VirtualInstrument()
      # The virtual instrument comprises input, output, setpoint, and
      # a PID.
      iface = ctrlr.Controller.virtualInstrumentController(
         config, driver)
   else:
      driver = Driver(drv.Serial(config.port))
      iface = ctrlr.Controller(config, driver)
      # We need at least one command.
      iface.addCommand(driver.SUBSYSTEM.COMMAND, "COLUMN_NAME")
   # We need at least one node.
   iface.addNode(0, "ROW_NAME")
   iface.populate()
   return iface
