how to generate sine table in pic16f873 in c programming

[sme7000]

i want to generate sinusoidal wave using sine table in ccp mode. i want to use 10 point per half cycle using natural sampling method..this point are store in sine table and can be call for anytime to do another jobs..(in my project this point are compare with triangular wave to produce a PWM wave). can anybody help me to create a sine table to store this point?:?:

Microchip have a free program, 'dsPICworks Data Analysis', which you can download from here:

**broken link removed**

You can use it to generate waveform tables.

Hi,
Try these values:
0, 79, 150, 207, 243, 256, 243, 207, 150, 79

what this value stand for? what is this value main function?

Dear Tahmid, Thanks for your very informative article "Generation and Implementing Sinewave Table". The pdf file on ifile.it no longer exists. can you give alternate source to download this. And my real question now is how you got those formulae for calculating the PWM Period ,PR2 values. Can you please describe in detail about those formulae.
