Module gpio

i.MX RT GPIO driver

Design

Allocate a Ports collection. Use this to access GPIO pins and GPIO ports.

• A Port maps to a GPIO pin bank. GPIO3 is a port. Ports may provide access to pins. Ports handle interrupts.
• A Pin maps to a physical GPIO pin. GPIO3[17] is a pin. It’s identified by its PinId, SdB0_05. Pins can be set as inputs or outputs.

Example

use imxrt10xx::gpio::{Ports, Port, PinId};

let ports = Ports::new(&ccm);
let pin_from_id = ports.pin(PinId::Emc25);
let pin_from_port = ports.gpio4.pin(25);
assert_eq!(pin_from_id as *const _, pin_from_port as *const _);
