asyncpio is an asynchronous Python client for pigpio, which allows control of the Raspberry Pi's General Purpose Input Outputs (GPIO).
This is a port of pigpio's thread-based Python client to asyncio.
pigpio is a dependency: you must have the pigpio daemon, pigpiod.
Create an asyncpio.pi() and await pi.connect(), then await the various pi.* function calls as you would for pigpio,
async def main():
pi = asyncpio.pi()
await pi.connect()
# ... await pi.<func> calls.
asyncio.run(main())You may call asyncpio.pi() outside of a running event loop if you need greater control over the loop,
async def main(pi):
await pi.connect()
# ... await pi.<func> calls.
pi = asyncpio.pi()
loop = asyncio.get_event_loop()
loop.run_until_complete(main(pi))See the pigpio Python documentation and EXAMPLES for the pi API.

ALL GPIO are identified by their Broadcom number. See https://pinout.xyz.
There are 54 GPIO in total, arranged in two banks.
Bank 1 contains GPIO 0-31. Bank 2 contains GPIO 32-54.
A user should only manipulate GPIO in bank 1.
There are at least three types of board:
It is safe to read all the GPIO. If you try to write a system GPIO or change its mode you can crash the Pi or corrupt the data on the SD card.
