readSerialLine() [1/2]

template<typename SerialIn>

fl::optional< fl::string > fl::readSerialLine	(	SerialIn &	serial,
		char	delimiter = '\n',
		fl::optional< u32 >	timeoutMs = fl::nullopt )

Read a line from a serial-like input source (blocking with optional timeout)

Template Parameters

SerialIn

Type providing available() and read() methods

Parameters

serial	Serial input source
delimiter	Line delimiter character (default: ' ')
timeoutMs	Optional timeout in milliseconds (nullopt = wait forever)

Returns

Optional string containing the line (without delimiter), or nullopt if timeout

Note

Follows Arduino's readStringUntil() style - blocks until complete line or timeout
