Hi,
Can anyone guide me to create a sine lookup table according to the adc value.I am new to PIC.so plz help me.
I am designin a UPS control with PID.here sine wave is generated according to the adc and triangle wave is generated with fixed amplitute.
Then these two will compare by comparator.
Plz tell me how to do this task.....
Assuming you mean DAC (not adc), write a simple program in your favorite language to spit out source code in whatever language you are using to program your micro. Best regards, Spehro Pefhany

So yo are designing a 'UPS control with PID' but ar unable to find the sine function in excel? Interesting skills set.

Start with Excel's Help menu. Look up or search for the SIN() worksheet function.

Perhaps it would be opportune to mention my book: Excel by Example: A Microsoft Excel Cookbook for Electronics Engineers published by Elsevier/Newnes ISBN: 0750677562
Amongst many other functions pertinent to electrical engineering, I also describe the sine function
