A kind of diary of reverse engineering the Behringer X32 to finally process audio with my own audio algorithms within the original audio DSPs...

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.

Motorcontrollers are everywhere, cheap and reliable, but building a field-oriented control (FOC) from scratch to understand the details is a nice challenge. So I accepted the challenge and implemented a full-featured FOC within an FPGA.

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.

Based on my Audioplayer-project I developed a DIY card for the Behringer X32. In addition to the youtube-video here you will find some more detailed information about this project and the implementation.

In this video I'm testing the DIY Expansion-Card for the Behringer X32 audio-mixing-console with the Room-EQ-Wizard-Software and I'm showing the new workflow using XTouch-Controllers and more things.

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.
