IO Serial Port Communicator

Aim

The task is to create a demonstrative version of a program, that is responsible for connecting to the serial port with provided parameters, send new data (binary or text), have the option to see the last message and have the ability to safely disconnect.

Input

Data required for connection:

Port Name
Baud Rate
Parity
Data Bits
Flow Control
Stop Bits

Output

Used Filters

Icon	Name	Description
	FormatIntegerToString	Useful for preparing a number for display or communication with specific number of digits, sign etc.
	SerialPort_Config	Configures the serial port.
	SerialPort_WriteString	Writes string characters to serial port.
	ReadIntegerArrayFromBuffer	Reads an array of integer values in specified binary format from a byte buffer.
	ConcatenateStrings	Joins two or more strings into a single one.
	ConcatenateStrings_OfArray	Joins multiple strings into a single one.
	SplitString	Divides the input string into an array of strings using the specified delimiters.
	RemoveNils	This filter is useful e.g. when inspecting multiple objects while some of the inspections may fail (Nil result). RemoveNils is used to ignore the failed cases in the final result.
	SerialPort_WriteBuffer	Writes raw binary data from a byte buffer to serial port.
	ParseInteger	Returns the integer number represented by a string.
	WriteIntegerArrayToBuffer	Converts an array of integer values into specified binary representation and writes it to a byte buffer.
	Loop	Put this filter into a task that should have a loop, but does not have any other loop generators (e.g. GrabImage).
	SerialPort_ReadBuffer	Reads raw binary data from serial port.
	ChooseByPredicate	E.g. to choose GREEN color to visualize correct objects or RED to visualize defective ones.
	LastMultipleObjects	Returns an array of most recent objects.
