Module capsules::gpio_async
[−]
[src]
Provides userspace applications with a driver interface to asynchronous GPIO pins.
Async GPIO pins are pins that exist on something like a GPIO extender or a radio that has controllable GPIOs.
Usage
Generate a list of ports to group into one userspace driver. let async_gpio_ports = static_init!( [&'static capsules::mcp23008::MCP23008; 1], [mcp23008]); let gpio_async = static_init!( capsules::gpio_async::GPIOAsync<'static, capsules::mcp23008::MCP23008<'static>>, capsules::gpio_async::GPIOAsync::new(async_gpio_ports)); // Setup the clients correctly. for port in async_gpio_ports.iter() { port.set_client(gpio_async); }
