dac sine wave
Hi,
I want to generate the a varaible sinewave from 10Hz to 50KHz using 8 bit microcontroller and and 12 bit DAC.I have read from the articles that from a look up table you can generate thefixed frewuency sinewave,but if i want to change the frequency i need to change the look up table again,since once microcontroller is programmed,there is least flexibality in changing the data written into its memory.So please suggest me ho to go aboput it ?
