AsyncGPIO allows easy access to the GPIO pins on your Raspberry Pi or similar embedded computer.
It is based on libgpiod and its CFFI adapter by Steven P. Goldsmith <sgjava@gmail.com>, as downloaded from github.
To run examples, make sure to install trio first.
Testing AsyncGPIO requires a Linux distribution that enables the mock-GPIO module. As of mid-2020, Debian's kernel does not include this module, but Raspbian's does.
If you can compile your own kernel: the option is named CONFIG_GPIO_MOCKUP, in Device Drivers / GPIO support / Memory mapped GPIO drivers / GPIO Testing Driver.
Writing an actual test suite is TODO. There is a more elaborate test script in DistKV-GPIO.
