sine wave generation

Question asked by mtbrewster on Feb 22, 2010

I need to generate several sine waves concurrently. Some are fixed freq., some are a single freq. which is selected by the control s/w and the freq. can change due to operator input, and 1 or 2 must be a scanning freq over a certain range. The sample rate is 48KHz. The processor is a Blackfin 548. I am not very familiar with the Blackfin but I noticed there is a sine function in the math library. Is this function suitable for generating sine waves in this scenario or is there a better way? If there is a better way, does someone have some example code?

 

Thanks,

 

Mike
