Running ChibiOS 2.4.3 with some modifications for the processor and LQFP144 package. I forget exactly what I had to do to enable the peripherals I wanted, but they weren't quite fully implemented yet.

@ErikZalm
What is it? Industrial controller?

@MitchD
What the IC between camera and MCU? Is it RAM?

I built an expansion board for the F4Discovery some time back.

Something from my side:

An SRAM and some LC-Filters are not populated yet. An SSD1963 based 5" touchscreen goes on top of that board (connector at the right edge).

"Arbitrary Waveform Generator by Joel Bodenmann"... looks more like a signal generator!

Ah, I'd never heard of SiliconBlue FPGAs before, interesting! Very nice board, btw!

It is an arbitrary signal generator. Three channels, DC to 20MHz each, -12 to +12V with full range offset, three selectable filter banks (or bypass).
The hardware mainly consists of an STM32F102CB, an STM32F407ZGT and an ICE40HX FPGA. And it runs ChibiOS/RT & µGFX, of course :)

Thanks, my "biggest" board so far (four layer, 0.1mm traces and impedance matching and all the crap).
