gpiod2go
Golang bindings for libgpiod v2.1.x
Link-time dependency is used
Incomplete surely, as I'm only interested in the very simple usecase to switch relais with a RaspberryPi
Building
Assuming you have Linux+go+gcc+pkgconf+libgpiod just do
cd cmd/example
CC=gcc go build
./example
Note that you need according rights to use /dev/gpiochip*
More Notes
Here are some of my notes I did while coding:
gpiod_line_request_set_value takes a 'request' and 'offset' and 'value', but 'request' has 'line_config' which has 'line_setting' which has 'offset' and 'value' again
--> why is this repeated?!
TODO consider using the plural version gpiod_line_request_set_values everytime, even for single lines
There is a mixture of 'free' and 'release' suffixes or missing '_new' prefix, e.g.
gpiod_line_settings_new -> gpiod_line_settings_free
gpiod_line_config_new -> gpiod_line_config_free
but
gpiod_chip_request_lines --> gpiod_line_request_release
