GPIO access via Trio and libgpiod
Project description
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.
