In this final episode I'll show how I implemented data-exchange with my card using IRQ and the development of some ShellExtensions and ControlPanel-applets for Windows98.

In part 2 of this series I will show my progress on developing a DIY PCI Card using Alteras FLEX10K FPGAs.

Ethernet on Microcontrollers is available without problems: using FreeRTOS or the Arduino-libs is always a good start. But for FPGAs? I was shocked how expensive Ethernet is for FPGAs - but I found a good solution...

Without the possibility to adjust the volume of individual frequency bands within an audio signal, modern audio would not sound the same. Today I'd like to show how I've implemented a EQ within my FPGA audio-mixer.

Implementing an audio-compression-algorithm in pure logic is a bit challenging as it uses a division. Time for some deep-diving into audio DSP with VHDL.

Plug&Play is a mystery to you? Until recently it was for me too, but let's take a look at the PCI specifications and lift the fog of mystery about PnP.

Todays digital-mixing-consoles are offering high number of audio-channels for processing. I was curious of how modern devices are dealing with realtime digital audio-data and had a look into some of these protocols.

Using an Arduino MKR Vidor4000 board I created a realtime multi-channel audiomixer with nice audio-processing-features.
