Struct Rfid 

pub struct Rfid<'a> { /* private fields */ }

Available on target_os=none only.

A device abstraction for an RFID reader using the MFRC522 chip.

use device_envoy::rfid::{Rfid, RfidEvent, RfidStatic};

    p: embassy_rp::Peripherals,
    spawner: embassy_executor::Spawner,

Implementations

impl Rfid<'_>

pub const fn new_static() -> RfidStatic

Create static channel resources for the RFID reader

pub async fn new<Sck, Mosi, Miso, Dma0, Dma1, Cs, Rst>( rfid_static: &'static RfidStatic, spi: Peri<'static, SPI0>, sck: Peri<'static, Sck>, mosi: Peri<'static, Mosi>, miso: Peri<'static, Miso>, dma_ch0: Peri<'static, Dma0>, dma_ch1: Peri<'static, Dma1>, cs: Peri<'static, Cs>, rst: Peri<'static, Rst>, spawner: Spawner, ) -> Result<Self>

where Sck: Pin + ClkPin<SPI0>, Mosi: Pin + MosiPin<SPI0>, Miso: Pin + MisoPin<SPI0>, Dma0: Channel, Dma1: Channel, Cs: Pin, Rst: Pin,

Create a new RFID reader device abstraction

Note: Currently hardcoded to SPI0. All peripherals must have ’static lifetime.

pub async fn wait_for_tap(&self) -> RfidEvent

Wait for the next RFID event (card detection)
