[][src]Enum rppal::spi::Error

pub enum Error {
    Io(Error),
    BitsPerWordNotSupported(u8),
    BitOrderNotSupported(BitOrder),
    ClockSpeedNotSupported(u32),
    ModeNotSupported(Mode),
    PolarityNotSupported(Polarity),
}

Errors that can occur when accessing the SPI peripheral.

Variants

Io(Error)

I/O error.

BitsPerWordNotSupported(u8)

The specified number of bits per word is not supported.

The Raspberry Pi currently only supports 8 bit words. Any other value will trigger this error.

BitOrderNotSupported(BitOrder)

The specified bit order is not supported.

The Raspberry Pi currently only supports the MsbFirst bit order. If you need the LsbFirst bit order, you can use the reverse_bits function instead to reverse the bit order in software by converting your write buffer before sending it to the slave device, and your read buffer after reading any incoming data.

ClockSpeedNotSupported(u32)

The specified clock speed is not supported.

ModeNotSupported(Mode)

The specified mode is not supported.

PolarityNotSupported(Polarity)

The specified Slave Select polarity is not supported.
