MATLAB: How to set Arduino TCCR1A and TCCR1B PWM-parameters in MATLAB

Question

Hello World,

It's needed to change Pulse-width modulation frequency on Arduino Board by Matlab, but could not find the way to do so.

In arduino coder it's perfectly realized by:

void setup()

{ TCCR1A = TCCR1A & 0xe0 | 1;

TCCR1B = TCCR1B & 0xe0 | 0x09;

}

but in MatLab?

Answer 1

In the Matlab Arduino package there is the file:

c:\ProgramData\MATLAB\SupportPackages\R2017a\toolbox\matlab\hardware\supportpackages\arduinoio\src\ArduinoServer.ino

Modify it setup() function:

void setup()

{ MWArduino.begin([connection_type]);

TCCR1A = TCCR1A & 0xe0 | 1;

TCCR1B = TCCR1B & 0xe0 | 0x09;

}
