Member Function Documentation

void swri_serial_util::SerialPort::Close

(

)

Close the serial port.

Definition at line 85 of file serial_port.cpp.

std::string swri_serial_util::SerialPort::ErrorMsg

(

)

const [inline]

Get the most recent error message.

Definition at line 150 of file serial_port.h.

bool swri_serial_util::SerialPort::Open	(	const std::string &	device,
		SerialConfig	config = SerialConfig()
	)

Open and configure the serial port.

The default configuration is: baud = 115200 parity = NO_PARITY flow control = false data bits = 8 stop bits = 1 low latency mode = false

Parameters:

[in]	device	The OS path of the device.
[in]	config	The port configuration settings.

Definition at line 94 of file serial_port.cpp.

int32_t swri_serial_util::SerialPort::ParseBaudRate

(

int32_t

baud

)

[private]

Parses integer and enumerated baud rates into enumerated baud rates.

Parameters:

[in]

baud

The baud rate (either integer or enumerated)

Returns:

The enumerated baud rate or -1 if invalid.

Definition at line 228 of file serial_port.cpp.

SerialPort::Result swri_serial_util::SerialPort::ReadBytes	(	std::vector< uint8_t > &	output,
		size_t	max_bytes,
		int32_t	timeout
	)

Read bytes from the serial port.

Appends up to max_bytes into the provided vector. If max_bytes is 0, it reads all available bytes.

Parameters:

[out]	output	The output buffer for bytes read in.
[in]	max_bytes	The maximum number of bytes to read. If set to 0, all available bytes are read.
[in]	timeout	The maximum time to block in milliseconds

Returns:

Read result (SUCCESS, TIMEOUT, INTERRUPTED, or ERROR).

Definition at line 352 of file serial_port.cpp.

bool swri_serial_util::SerialPort::SetLowLatencyMode

(

)

[private]

Attempts to put serial port in low latency mode.

Definition at line 201 of file serial_port.cpp.

int32_t swri_serial_util::SerialPort::Write

(

const std::vector< uint8_t > &

input

)
