MSP430G2533: Energia IDE Multiple PWM generation with different Duty Cycle

Hi,

I assume you arecurrently using the 20 pin package(PW20 or N20), right?

In general you can certainly generate two PWM with different period and duty cycle.
Please be aware that for the 20 pin package, both pin 9 and pin 10 use the OUT1 of Timer_A1 and will therefor show the same PWM signal.
To generate two different PWM make sure you use pins that are connected to different Timer outputs such as pin 8 and 9 of the 20 pin package.

"Let me know how to generate two PWM with different period and Duty cycle ."

the simplest and easiest would be to use two timers.

if the frequency is low and you don't need full range 0-100% dc, you can do it with one timer.

Thanks for your response .
I know
analogFrequency(77000);
function to assign particulate frequency ..
I am looking for sample code to generate two different frequency with different Duty cycle..

Hi,

did you try to use the analogWrite() function after switching to pins that use two different timers?
That way, by adapting the function parameters you should be able to generate two PWM with different frequency and duty cycle.

Hello,

 

Later i tried with PIN 9 and PIN 14 then i able to change different duty cycle for both pin .

But i am not able to create two different frequency for PIN9 and PIN 14.
