jevois::Serial Class Reference

#include <jevois/Core/Serial.H>

Interface to a serial port.

This class is thread-safe. Concurrent read and write (which do not seem to be supported by the O.S. or hardware) are serialized through the use of a mutex in the Serial class.

◆ fileGet()

void jevois::Serial::fileGet ( std::string const &  abspath)

Send a file from the local microSD to the host computer.

abspath should be the full absolute path of the file. The port will be locked during the entire transaction.

◆ filePut()

void jevois::Serial::filePut ( std::string const &  abspath)

Receive a file from the host and write it to the local microSD.

abspath should be the full absolute path of the file. The port will be locked during the entire transaction.

◆ readSome()

bool jevois::Serial::readSome ( std::string &  str)
overridevirtual

Read some bytes if available, and return true and a string when one is complete.

This would usually only make sense to use in non-blocking mode.

Implements jevois::UserInterface.

Definition at line 262 of file Serial.C.

References jevois::imu::get(), and SERFATAL.

◆ sendBreak()

void jevois::Serial::sendBreak ( void  )

transmit continuous stream of zero-valued bits for specific duration.

Definition at line 253 of file Serial.C.

◆ setBlocking()

void jevois::Serial::setBlocking ( bool  blocking,
std::chrono::milliseconds const &  timeout 
)

Set the access to blocking or not.

Default is non-blocking. If blocking, can also specify a timeout (rounded to tenth of seconds)

Definition at line 213 of file Serial.C.

◆ toggleDTR()

void jevois::Serial::toggleDTR ( std::chrono::milliseconds const &  dur)

Set the DTR mode off momentarily.

◆ type()

jevois::UserInterface::Type jevois::Serial::type ( ) const
overridevirtual

Return our port type, here Hard or USB.

Implements jevois::UserInterface.

Definition at line 415 of file Serial.C.

◆ writeString()

void jevois::Serial::writeString ( std::string const &  str)
overridevirtual

Write a string, using the line termination convention of serial::linestyle.

No line terminator should be included in the string, writeString() will add one.
