Firmware description
===================
This firmware contains a DSP library and a demo running on the STM3210B-EVAL board.
The DSP library is s suite of common DSP functions, which are:
- PID controller.
- Complex 16-bit radix-4 FFT, 64, 256 and 1024 points.
- FIR 16-bit filter.
- IIR Direct Form I 16-bit filter.
- IIR Canonical Form 16-bit filter.
For more information, please refer to the user manual provided with this firmware.
The demo illustrates the use of the FFT function of the DSP library. It consists on applying the 64-points FFT transformation
to two variable frequency waves, which are a sinus and a dual sinus. The waves and the result of the FFT transformation
are displayed on the LCD of the STM3210B-EVAL board.
