Serial I/O

Introduction

Small set of Scilab/Xcos blocks designed for serial communication in Linux. Source code available on request, please send e-mail to fabo(dot)peter(at)gmail(dot)com.

Pipe (FIFO) interface

Simple interprocess communications (peer to peer) via Linux (POSIX) system FIFO.

	Block for writing into the FIFO. Input scalar value (double) is converted to a string terminated with '\n' and entered into FIFO.
	Block for reading from FIFO. Reads strings terminated with '\n' from FIFO and converts it into double.

Usage

debugging
real-time data exchange with others programs (Scada ...)
communication with separated GUI programs
etc ...

Examples

Writing data to the pipe

Reading from pipe(s)

Reading/writing from/to pipes

Standard serial interface

Communication with standard serial devices (/dev/tty****) - USART, USB/RS232 adapters with FTDI chips and virtual serial ports (/dev/pts/*)

	Block for writing <0.0 ... 255.0> double vector[max 32] in the serial device. Negative values are ignored.
	Block for reading double vector[max 32] from serial device with timeout. Standard value range <0.0 ... 255.0>, -1 after timeout.
