Does STM32F103C8 has DAC?

[svraj]

hello all,

I am trying to generate SPWM using STM32F103C8, does it require DAC.

i am confused help me out of it.

Thank in advance

Are you speaking about Sinusoidal Pulse Width Modulation ?

That method is about creating a sinus-like signal without analog output.

The F103 does have a DAC unit, though.

Thanks for your response.

Yes, You are right I am speaking Sinusoidal PWM. Do you Know how to do it using F103?

Not practically.

Using PWM and continuously updating the duty cycle would be one method. I reckon that could become a bit difficult for high (sinus) frequencies.
