Expand description

Full duplex (master mode)


  • It’s the task of the user of this interface to manage the slave select lines

  • Due to how full duplex SPI works each read call must be preceded by a send call.

  • Some SPIs can work with 8-bit and 16-bit words. You can overload this trait with different Word types to allow operation in both modes.

Required Associated Types

An enumeration of SPI errors

Required Methods

Reads the word stored in the shift register

NOTE A word must be sent to the slave before attempting to call this method.

Sends a word to the slave


FullDuplex trait implementation, allowing this struct to be provided to drivers that require it for operation. Only 8-bit word size is supported for now.
