I recently got my DSP56807 to work on my audio application in school. I am having a problem understanding the concept of the SDK and with the ADC. To avoid aliasing and designing a tedious analog filter, I have to sample my signal at 500kHz and that's where I run into the problem. I read over the ADC samples from Motorola but could not understand them clearly. I could not figure out how to setup the time for 500kHz. Can someone please explain the concept to me or show me how to set up the timer to get the sample at 500kHz? Thank you, Si Diep |
