esp-hal-MFRC522
Non-blocking RFID library for esp-hal (maybe for other hal's in the future). This project is just "port" of this Arduino Library.
Example
let dma = Dma::new(peripherals.dma);
let dma_chan = dma.channel0;
let (descriptors, rx_descriptors) = dma_descriptors!(32000);
let dma_chan = dma_chan.configure_for_async(false, esp_hal::dma::DmaPriority::Priority0);
let cs = Output::new(io.pins.gpio5, Level::High);
let spi = Spi::new(peripherals.SPI3, 5.MHz(), SpiMode::Mode0, &clocks);
let spi: Spi<SPI3, FullDuplexMode> = spi.with_sck(io.pins.gpio4).with_miso(io.pins.gpio2).with_mosi(io.pins.gpio3);
let spi: SpiDma<SPI3, _, FullDuplexMode, Async> =
spi.with_dma(dma_chan, descriptors, rx_descriptors);
//mfrc522_esp_hal::MFRC522::new(spi, cs, || esp_hal::time::current_time().ticks());
let mut mfrc522 = mfrc522_esp_hal::MFRC522::new(spi, cs); // embassy-time feature is enabled,
// so no need to pass current_time
// function
_ = mfrc522.pcd_init().await;
_ = mfrc522.pcd_selftest().await;
log::debug!("PCD ver: {:?}", mfrc522.pcd_get_version().await);
if !mfrc522.pcd_is_init().await {
log::error!("MFRC522 init failed! Try to power cycle to module!");
}
loop {
if mfrc522.picc_is_new_card_present().await.is_ok() {
let card = mfrc522.get_card(UidSize::Four).await;
if let Ok(card) = card {
log::info!("Card UID: {}", card.get_number());
// this function dumps card blocks using log::debug
// use mfrc522_esp_hal::debug::MFRC522Debug;
//
//_ = mfrc522.debug_dump_card(&card).await;
}
_ = mfrc522.picc_halta().await;
}
Timer::after(Duration::from_millis(1)).await;
}
