MATLAB Support Package for Arduino (also referred to as "ArduinoIO Package") allow s you to communicate w ith an Arduino Uno or Duemilanove over a serial port. It consists of a MATLAB API on the host computer and a server program that runs on the Arduino. Together, they allow you to access Arduino analog I/O, digital I/O, operate servo motors, read encoders, and even handle dc and stepper motors using the adafruit motor shield, all from the MATLAB command line. The Support Package also includes Simulink blocks for communicating w ith the Arduino. For more information about the Support Package, see: http://w w w .mathw orks.com/hardw are-support/arduino-matlab.html For Simulink blocks that support code generation, see: http://w w w .mathw orks.com/hardw are-support/arduino-simulink.html Sample usage: %-- connect to the board a = arduino('COM9') %-- specify pin mode a.pinMode(4,'input'); a.pinMode(13,'output'); %-- digital i/o a.digitalRead(4) % read pin 4 a.digitalWrite(13,0) % w rite 0 to pin 13 %-- analog i/o a.analogRead(5) % read analog pin 5 a.analogWrite(9, 155) % w rite 155 to analog pin 9 %-- serial port a.serial % get serial port a.flush; % flushes PC's input buffer a.roundTrip(42) % sends 42 to the arduino and back %-- servos a.servoAttach(9); % attach servo on pin #9 a.servoWrite(9,100); % rotates servo on pin #9 to 100 degrees val=a.servoRead(9); % reads angle from servo on pin #9 a.servoDetach(9); % detach servo from pin #9 %-- encoders a.encoderAttach(0,3,2) % attach encoder #0 on pins 3 (pin A) and 2 (pin B) a.encoderRead(0) % read position a.encoderReset(0) % reset encoder 0 a.encoderStatus; % get status of all three encoders a.encoderDebounce(0,12) % sets debounce delay to 12 (~1.2ms) a.encoderDetach(0); % detach encoder #0 %-- adafruit motor shield (w ith AFMotor library) a.motorRun(4, 'forw ard') % run motor forw ard a.stepperStep(1, 'forw ard', 'double', 100); % move stepper motor %-- close session delete(a) Acknow ledgem ents Real Time Pacer For Simulink inspired this file.
