IO Serial Port Communicator
目的
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.
Data required for connection:
- Port Name
- Baud Rate
- Parity
- Data Bits
- Flow Control
- Stop Bits

使用したフィルタ
アイコン | 名前 | 説明 |
---|---|---|
ChooseByPredicate | E.g. to choose GREEN color to visualize correct objects or RED to visualize defective ones. | |
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. | |
ConcatenateStrings_OfArray | Joins multiple strings into a single one. | |
SerialPort_Config | Configures the serial port. | |
SerialPort_WriteString | Writes string characters to serial port. | |
SerialPort_ReadBuffer | Reads raw binary data from serial port. | |
WriteIntegerArrayToBuffer | Converts an array of integer values into specified binary representation and writes it to a byte buffer. | |
SerialPort_WriteBuffer | Writes raw binary data from a byte buffer to serial port. | |
Loop | このフィルターを、ループを持つ必要があるタスクに配置しますが、他のループ ジェネレーター (例: GrabImage) を持たないようにします。 | |
LastMultipleObjects | Returns an array of most recent objects. | |
ParseInteger | Returns the integer number represented by a string. | |
FormatIntegerToString | Useful for preparing a number for display or communication with specific number of digits, sign etc. | |
ConcatenateStrings | Joins two or more strings into a single one. | |
SplitString | Divides the input string into an array of strings using the specified delimiters. | |
ReadIntegerArrayFromBuffer | Reads an array of integer values in specified binary format from a byte buffer. |
