PWM with variable frequency

  Correct AnswerRe: PWM with variable frequency     

I created a custom LIFA function based on your Arduino code.  I made some assumptions since I did not have that include file (I was also unable to compile for the same reason).

Take a look at the code to see if my assumptions were correctly.  Let me know if it works.

Attachments:

• LIFA_Base.zip (36.4 K)  
• Set PWM.vi (733.8 K)  

This looks like it would solve my PWM frequency control problem but when I upload LIFA_Base I get the following errors:

LabVIEWInterface.ino: In function 'bool set_pwm_freqency(char, int, char)':

LabVIEWInterface:887: error: 'SetPinFrequencySafe' was not declared in this scope

LabVIEWInterface:890: error: 'pwmWrite' was not declared in this scope

I'm new at this so I'm probably doing something wrong. Any idea what's causing these errors?

It looks like you need to get the PWM.h library.  I'm not sure if I ever had it and was just basing my code on what maudTU posted.

Thanks! I'll install the library and give it a try.
