Double click on the block to let the following dialog box appear: This allows a serial communication between Arduino and Scilab. Start to build the Xcos schema, with the configuration blocks: This sketch is based on the demo “potentiometre” of the Arduino toolbox: annexe 2 for the scilab code generating this graphical user interface (with the serial communication)Īlternative procedure with the Arduino toolbox for Xcos Go on the following website: ‐arduino And download the following file: toolbox_arduino_v3.ino Plug your Arduino Board to your PC, open the Arduino IDE and flash the file toolbox_arduino_v3.ino on the Arduino Board. Graphical User Interface 2: historical temperature values visualizationĬf. annexe 1 for the scilab code generating this graphical user interface ![]() Graphical User Interface 1: instant temperature value visualizationĬf. We have to enter the communication parameters, in the form "baud,parity,data_bits,stop_bits": -‐-‐>h=openserial(1,"9600,n,8,1") Second, we will in this case read the data on the serial port, coming from the temperature sensor on the Arduino board: -‐-‐>readserial(h) At last, as we have received the data, we have to close the serial communication: -‐-‐>closeserial(h) Open serial communication Read/write on the serial communication Close the serial communicationįirst we open the serial communication on the COM port 1 (example running on Windows OS). The way to exchange data with the serial communication is the following: -‐ -‐ -‐ ![]() The serial communication toolbox enables to get the data wired through this protocol in Scilab. Scilab-‐side script for temperature acquisition The temperature acquisition is directed through the serial communication from the Arduino board to the pc. * We initialize the serial connection with the computer 9. * setup() -‐ this function runs once when you turn your Arduino on 8.
