thank you very much for your reply.
I try to generate the fft of any signal in the range of and
calculate the magnitude of each frequency
I use the SPI link between ADC and DSP Blackfin 533.
I want to know what value of sampling frequency should I use? (knowing that I
want to measure the amplitudes of each frequency of 150Hz to 3kHz)
Which registers do I put this value?
What is the values of registers SPI_BAUD, PLL_DIV?
how to calculate?
here the code for the initialization of the register SPI I use:
void Setup_SPI(void)
{
*pSPI_BAUD=0x0004; // !!!
*pSPI_CTL=0x110a; }
/ / in the main:
pPLL_DIV = 6;
PS: Blackfin DSP 533, ADC = AD7982.
I have read the datasheet, but I can not find the solution.
Please help me
