Data acquisition and device control with Scilab.
Desciription
Scilab is a freeware alternative to MATLAB. For low-cost data acquisition and device control a nice Arduino toolbox is available.
This site presents a Mbed port which allows to use Mbed boards (equipped with Arduino header) rather than Arduino to import real time data into Scilab and to control real equipment witch Scilab.
Installation
- Install Scilab to your PC, if not done yet.
- Launch Scilab and install the Arduino toolbox by executing the following command from the Scilab console:
--> atomsInstall("arduino")
Controlling Mbed's digital output from Scilab
- In Xcos open
examples/Arduino1.zcos
- Double click on the
Board
setup block and replace the serial port number with mbed's actual virtual serial port number.
- Double click on the
Digital WRITE
block and set Digital Pin to 13 (D13 is connected to LED1).
- Start simulation and LED1 on the Mbed board should start blinking.
Reading and displaying Mbed's analog input
- In Xcos open
examples/Arduino2.zcos
- Double click on the
Board
setup block and replace the serial port number with mbed's actual virtual serial port number.
- Double click on the
Analog READ
block and set Analog Pin to 2.
- Start simulation and a graph should appear showing the analog signal measured on Mbed's pin A2.
NOTE: Currently, there is bug in the toolbox ARDUINO_ANALOG_READ_sim function (I have reported to Scilab) so the analog readings are not correct.
PID controller
- In Xcos open
examples/Arduino9.zcos
