STM32F10x DSP demo description

The STM32F10x DSP demo is an example that illustrates how to use the 64-point FFT

function of the STM32F10x DSP library. It consists of an LCD that displays the FFT

transformation.

The demo runs on the STM3210B-EVAL board, and shows the 64-point FFT transformation

of two signals:

1.

a sine wave

2.

a dual sine wave

The two types of wave are displayed at variable frequencies and for each frequency the FFT

is computed and the result is plotted as shown in Figure 5:
