void abort_read ( )

inherited

Abort the on-going read transfer.

It is safe to call abort_read() when there is no on-going transaction.

void abort_write ( )

inherited

Abort the on-going write transfer.

It is safe to call abort_write() when there is no on-going transaction.

void attach	(	Callback< void()>	func,
		IrqType	type = `RxIrq`
	)

inherited

Attach a function to call whenever a serial interrupt is generated.

Parameters

func	A pointer to a void function, or 0 to set as none
type	Which serial interrupt to attach the member function to (Serial::RxIrq for receive, TxIrq for transmit buffer empty)

void attach	(	T *	obj,
		void(T::*)()	method,
		IrqType	type = `RxIrq`
	)

inherited

Attach a member function to call whenever a serial interrupt is generated.

Parameters

obj	pointer to the object to call the member function on
method	pointer to the member function to be called
type	Which serial interrupt to attach the member function to (Serial::RxIrq for receive, TxIrq for transmit buffer empty)

Deprecated:: The attach function does not support cv-qualifiers. Replaced by attach(callback(obj, method), type).

Definition at line 121 of file SerialBase.h.

void attach	(	T *	obj,
		void()(T )	method,
		IrqType	type = `RxIrq`
	)

inherited

Attach a member function to call whenever a serial interrupt is generated.

Parameters

obj	pointer to the object to call the member function on
method	pointer to the member function to be called
type	Which serial interrupt to attach the member function to (Serial::RxIrq for receive, TxIrq for transmit buffer empty)

Deprecated:: The attach function does not support cv-qualifiers. Replaced by attach(callback(obj, method), type).

void baud ( int baudrate )

inherited

Set the baud rate of the serial port.

Parameters

baudrate The baudrate of the serial port (default = 9600).

void clear_break ( )

inherited

Clear a break condition on the serial line NOTE: Should be run at least one frame after set_break is called.

void enable_input ( bool enable = true )

inherited

Enable serial input.

If both serial input and serial output are disabled, the peripheral is freed. If either serial input or serial output is re-enabled, the peripheral is reinitialized.

On re-initialization rx interrupts will be enabled if a rx handler is attached. The rx handler is called once during re-initialization.

void enable_output ( bool enable = true )

inherited

Enable serial output.

If both serial input and serial output are disabled, the peripheral is freed. If either serial input or serial output is re-enabled, the peripheral is reinitialized.

On re-initialization tx interrupts will be enabled if a tx handler is attached. The tx handler is called once during re-initialization.

void format	(	int	bits = `8`,
		Parity	parity = `SerialBase::None`,
		int	stop_bits = `1`
	)

inherited

Set the transmission format used by the serial port.

Parameters

bits	The number of bits in a word (5-8; default = 8)
parity	The parity used (SerialBase::None, SerialBase::Odd, SerialBase::Even, SerialBase::Forced1, SerialBase::Forced0; default = SerialBase::None)
stop_bits	The number of stop bits (1 or 2; default = 1)

int getc ( )

inherited

Read a char from the serial port.

Returns: The char read from the serial port

int putc ( int c )

inherited

Write a char to the serial port.

Parameters

c	The char to write

Returns: The written char or -1 if an error occurred

int puts ( const char * str )

inherited

Write a string to the serial port.

Parameters

str	The string to write

Returns: 0 if the write succeeds, EOF for error

int read	(	uint8_t *	buffer,
		int	length,
		const event_callback_t &	callback,
		int	event = `SERIAL_EVENT_RX_COMPLETE`,
		unsigned char	char_match = `SERIAL_RESERVED_CHAR_MATCH`
	)

inherited

Begin asynchronous reading using 8bit buffer.

The read operation ends with any of the enabled events and invokes registered callback function (which can be NULL to not receive callback at all). Events that are not enabled by event argument are simply ignored. Operation has to be ended explicitly by calling abort_read() when no events are enabled. This function locks the deep sleep until any event has occurred.

Parameters

buffer	The buffer where received data will be stored
length	The buffer length in bytes
callback	The event callback function
event	The logical OR of RX events that should end operation
char_match	The matching character

Returns: Zero if new transaction was started, -1 if transaction is already on-going

int read	(	uint16_t *	buffer,
		int	length,
		const event_callback_t &	callback,
		int	event = `SERIAL_EVENT_RX_COMPLETE`,
		unsigned char	char_match = `SERIAL_RESERVED_CHAR_MATCH`
	)

inherited

Begin asynchronous reading using 16bit buffer.

The read operation ends with any of the enabled events and invokes registered callback function (which can be NULL to not receive callback at all). Events that are not enabled by event argument are simply ignored. Operation has to be ended explicitly by calling abort_read() when no events are enabled. This function locks the deep sleep until any event has occurred.

Parameters

buffer	The buffer where received data will be stored
length	The buffer length in bytes
callback	The event callback function
event	The logical OR of RX events that should end operation
char_match	The matching character

Returns: Zero if new transaction was started, -1 if transaction is already on-going

int readable ( )

inherited

Determine if there is a character available to read.

Returns: 1 if there is a character available to read, 0 otherwise

void send_break ( )

inherited

Generate a break condition on the serial line.

void set_break ( )

inherited

Generate a break condition on the serial line NOTE: Clear break needs to run at least one frame after set_break is called.

int set_dma_usage_rx ( DMAUsage usage )

inherited

Configure DMA usage suggestion for non-blocking RX transfers.

Parameters

usage The usage DMA hint for peripheral

Returns: Zero if the usage was set, -1 if a transaction is on-going

int set_dma_usage_tx ( DMAUsage usage )

inherited

Configure DMA usage suggestion for non-blocking TX transfers.

Parameters

usage The usage DMA hint for peripheral

	)

inherited

Set the flow control type on the serial port.

Parameters

		int	length,
		const event_callback_t &	callback,
		int	event = `SERIAL_EVENT_TX_COMPLETE`
	)

inherited

		int	event = `SERIAL_EVENT_TX_COMPLETE`
	)

inherited
