IIR FILTER - FIXED33:48
Implement and test IIR Filters using fixed point format
IIR FILTER – REAL TIME ADC APPLICATION1:13:52
Implement a realtime filter application using microcontroller ADC, DAC and DMA peripherals

This course intend to explore filter implementations and proof of concept task, so, we'll not introduce filter theory in the next video lessons.

Focusing in CMSIS DSP library we gonna implement IIR and FIR Filters, exploring Floating and Fixed point formats.

STM32CubeIDE is an integraded development tool you can develop different programs for STM32 microcontrollers

its advanced C or C++ development platform with bunch of peripheral configuration, code generation, compilation

and also debbuging features for all STM32 microcontrollers and microprocessors.

We'll also explore the STM32 CubeMonitor, witch is primarely a monitoring tool for STM32 microcontrollers running

embedded firmware. You can set and watch application variables at runtime for example.

The STM32CubeMonitor can be deeply customized by the user, as it relies on web technologies and more specifically

on the Node-Red. In this course, for example, we gonna create a interface to extract data from a user generated

spreadsheet, copy its content to runtime input variable, process this content, generate output content and store

the values in a output generated spreadsheet. This is all done inside the CubeMonitor interface.

Other important software resourses in order to generate filter coefficients and analyze graphically it's response

is the GNU Octave

GNU Octave is a powerful mathematics-oriented syntax with built-in 2D/3D plotting and visualization tools

its free and compatible with many Matlab scripts.

We gonna also use Excel and Notepad++ in order to manipulate our .csv Spreadsheets.

In the hardware side, we gonna use STM32F407ZGT6 Development board. We also need a ST-Link programmer if we

not choose the STM32F4Discovery development board, as this board comes with a ST-Link/V2 embedded debug tool.

For real time ADC application, as the video lesson 7, it's necessary aditional components as a Osciloscope in order

to analyse input and output signal in time domain. A signal generator, in order to generate the input signal.

And some Dupont Jumpers in order to connect those signals in the proper microcontroller pins.
