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?

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;
}

hi,i want to change arduino pwm frequency using simulink Arduino package,i used arduino pwm block in simulink,but it can not change pwm frequency.i set Arduino TCCR1A and TCCR1B PWM-parameters following your answer, it works in matlab,but it does not work in simulink.
so,i want to know how to change arduino pwm frequency using simulink?thank you for your reply!
if you have any ideas,please reply me or email to me:1945235463@qq.com.thank you very much!
