HAL Interface
This module allows the creation of userspace HAL components in Python. This includes pins and parameters of the various HAL types.
Example:
from qtpyvcp import hal
# create a new component and add some pins
comp = hal.getComponent("loop-back")
comp.addPin("in", "float", "in")
comp.addPin("out", "float", "out")
# mark the component as 'ready'
comp.ready()
# define a function to call when the input pin changes
def onInChanged(new_value):
# loop the out pin to the in pin value
comp.getPin('out').value = new_value
# connect the listener to the input pin
comp.addListener('in', onInChanged)
