HAL InterfaceΒΆ

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.component("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)
