}
Expand description

Read half of a serial interface

Some serial interfaces support different data sizes (8 bits, 9 bits, etc.); This can be encoded in this trait via the Word type parameter.

Required Associated Types

Read error

Required Methods

Reads a single word from the serial interface

Implementors

Implement serial::Read for Rx Spi structs in Slave OpMode

serial::Read is only implemented for Spi structs with Rx Capability. In Slave OpMode, Read does not have to initiate transactions, so it does not have to store any internal state. It only has to wait on RXC.

Implement serial::Read for Rx Spi structs in a MasterMode

serial::Read is only implemented for Spi structs with Rx Capability. In a MasterMode, Read has to initiate transactions, so it keeps track of the transaction state. If a transaction is in progress, it will wait on RXC. If not, it will wait on DRE, and then send 0.
