pigpio is a Python module for the Raspberry which talks to
the pigpio daemon to allow control of the general purpose
input outputs (GPIO).
[http://abyz.me.uk/rpi/pigpio/python.html]
*Features*
o the pigpio Python module can run on Windows, Macs, or Linux
o controls one or more Pi's
o hardware timed PWM on any of GPIO 0-31
o hardware timed servo pulses on any of GPIO 0-31
o callbacks when any of GPIO 0-31 change state
o creating and transmitting precisely timed waveforms
o reading/writing GPIO and setting their modes
o wrappers for I2C, SPI, and serial links
o creating and running scripts on the pigpio daemon
*GPIO*
ALL GPIO are identified by their Broadcom number.
*Notes*
Transmitted waveforms are accurate to a microsecond.
Callback level changes are time-stamped and will be
accurate to within a few microseconds.
*Settings*
A number of settings are determined when the pigpio daemon is started.
o the sample rate (1, 2, 4, 5, 8, or 10 us, default 5 us).
o the set of GPIO which may be updated (generally written to). The
default set is those available on the Pi board revision.
o the available PWM frequencies (see [*set_PWM_frequency*]).
*Exceptions*
By default a fatal exception is raised if you pass an invalid
argument to a pigpio function.
If you wish to handle the returned status yourself you should set
pigpio.exceptions to False.
You may prefer to check the returned status in only a few parts
of your code. In that case do the following:
...
pigpio.exceptions = False
# Code where you want to test the error status.
pigpio.exceptions = True
...
*Usage*
This module uses the services of the C pigpio library. pigpio
must be running on the Pi(s) whose GPIO are to be manipulated.
The normal way to start pigpio is as a daemon (during system
start).
sudo pigpiod
Your Python program must import pigpio and create one or more
instances of the pigpio.pi class. This class gives access to
a specified Pi's GPIO.
...
pi1 = pigpio.pi() # pi1 accesses the local Pi's GPIO
pi2 = pigpio.pi('tom') # pi2 accesses tom's GPIO
pi3 = pigpio.pi('dick') # pi3 accesses dick's GPIO
pi1.write(4, 0) # set local Pi's GPIO 4 low
pi2.write(4, 1) # set tom's GPIO 4 to high
pi3.read(4) # get level of dick's GPIO 4
...
The later example code snippets assume that pi is an instance of
the pigpio.pi class.
