Module imxrt_hal::iomuxc::pin_config

Pin configuration

All GPIOs take a given PinConfig that specifies features like

• pull up/down resistor connectivity and resistance
• pin speed
• pin drive strength

If the PinConfig does not write to all fields, which is checked by PinConfig::is_modify() the config is applied as a modification to the current PAD_MUX_PAD register value.

Otherwise the PAD_MUX_PAD register is overwritten with the new configuration.

PinConfig docs supply more information on how to build a PinConfig and what typical defaults from the reference manual look like.

Example using const builder functions

use imxrt_hal::iomuxc::pin_config::*;
use imxrt_hal::Peripherals;

const LED_PIN_CONFIG: PinConfig = PinConfig::with_none()
                     .set_pull_up(PullUp::PullUp_100KOhm)
                     .set_speed(Speed::Speed2_150MHz)
                     .set_drive_strength(DriveStrength::R0_DIV_6);
let mut peripherals = Peripherals::take().unwrap();
peripherals.iomuxc.gpio_ad_b0_00.configure(&LED_PIN_CONFIG);
