Below are a few snippets of example usage. For more thorough usage, please see the source code.
pollGridFrequency()
Polls every 0.5s [default], only printing result [default]. Calls callback only if value changed [default]
pollGridFrequency(my_callback, 0.1)
Polls with custom callback function my_callback
taking ONE argument (frequency). I.e. my_callback(freq) is called. Custom refresh rate.
pollGridFrequency(None, 2, False)
No callback (prints values only), polling every 2s and returning values regardless of whether they have changed.
print("This is freq: " + str(getCurrentFrequency()[1]))
Single-capture frequency.
The data obtained in the continous polling is passed to a provided callback. The format of the callback is as follows
def my_callback(frequency):
desired_freq = 50
print("We differ by {} Hertz".format((desired_freq - frequency))
