Here's the code I'm testing with so far:

    let mut dma = Dma::new(dp.DMA1, &mut dp.RCC);
    spi.enable_dma(&mut dma);

    let mut xmit_buf = [0x00_u8]; // Buffer to request a read of the config data.
    let mut read_buf = [0_u8; 1];  // Buffer to place the resulting read in.

    loop {
        cs_rtd.set_low();
        spi.write_dma(xmit_buf, &mut dma);
        cs_rtd.set_high();

        delay.delay_ms(100);

        cs_rtd.set_low();
        spi.read_dma(read_buf, &mut dma);
        cs_rtd.set_high();

        delay.delay_ms(1_000);
    }

Would it be possible to impl the e-h blocking traits in embassy in such a way that other tasks could continue while one is blocking?

no :(

not with async/await at least. With a full RTOS (with actual threads with a stack each) it'd be definitely possible

Oops: Correction to above:

    let mut xmit_buf = DmaWriteBuf { buf: [0x00_u8] }; // Buffer to request a read of the config data.
    let mut read_buf = DmaReadBuf { buf: [0_u8; 1] };  // Buffer to place the resulting read in.

hi all! I'm new to the embedded rust world--but have about a year of experience from school, I'm really comfortable with the tm4c123 launchpad. Does anyone know of any issues with systick in the tm4c123x hal? My led seems to be staying on/off for double the amount of time specified...I apologize in advance for a trivial solution lol. ignore the & on the embedded_hal::digital lines, i quickfixed it and forgot to remove those
