Sine Wave Genration useing dspic33

[ALLPIC]

Hello every one.

Can somebody help me to generate sine wave useing PWM single phase. I seen lot of application note on microchip but now gating more and more confuse. I need a simple thing that let generate simple sine wave no feedback.

There are some technique to generate a sine wave from table. I think that will be best for me.

Some body please help me

thanks in advance

Example in Basic, very simple !

Hello,

Here is a method "Magic  Sinewaves" to generate sine wave from PWM, i think it could help you.

I think so, it's necessary to search, because the site is not very easy to explore.

Here a good project, using PIC16F628 to generate Sine, Square, Pulse, Noise, Ramp ... (using wave table) using DDS software and use PWM to generate signal.

May be it's interesting for other people who want generating "user wave" like ECG wave with PWM.

Best Regards.

I got soulation with microchip app note



Please check attachment this is generating sine wave this will be helpful for every one interested for doing UPS inverter or something motor control

once again thanks for helping me

regards

by connecting 2.2k resistor and 0.1uf capacitor to ground you will observe a sinewave at PWM1H I am useing dspic33fj12MC202
