I'm interested in doing some audio work on fpga. At a minimum this requires a decent dac/adc. Can anyone recommend a cheap board that provides this onboard? Seems most kits with audio also contain video and got for around $400 AUD

#22Specs: • 1280 Four input LUT logic cells • 64Kbit of RAM • 32Mbit flash • a PLL • Two sets of 8 digital I/O pins • One Pmod connector (2x6 0.10" socket, some sort of digital interface) • 5 LEDs • An IrDA transceiver • USB dongle form factor, programmed from USB, can look like a UART from FPGA to PC The design software appears to only function on the Windows operating system.
Windows is par for the course. If you want to develop for FPGAs, I suggest you accept Windows, at least to start with. Xilinx can run on Linux and all that, but Windows is the path of least resistance, and FPGAs will give you enough trouble by themselves!
I don't think HN is really the place to accept this kind of status quo. We're not here to maintain a tradition. Somehow, I would be very glad that someone here break this barrier (not me, I'm trying to do that for the CNC world).
Re: Lattice's $24.99 FPGA Evaluation Kit
#23It's great that Lattice is coming out with even cheaper FPGA dev board options. The bare-bones student dev kits from Altera and Xilinx are typically around $70, but $25 is a low enough price for hobbyists and beginners to begin experimenting as well. I'm not too sure about the USB stick form factor, though. I have Texas Instrument's F2013 dev board[0], which is also a USB stick-type device. It's adorable; it's cute;…
Personally I'd prefer it if the dev boards skip the demo peripherals and bring out all the I/O pins.

#24Any suggestions of starter FPGA projects for someone who is a programmer but wants to get into FPGAs?
find some other chip you like, and write an interface for it.

Our FPGA work is all done on Linux, but we're coming from the HPUX world. We've used Xilinx and Altera without any problems to speak of.

I'm not going to register just to check out prices, but a quick google landed me at http://www.fpga.biz/product_info.php?products_id=87. Doesn't look like it'll be cheap, though - anyone know how much this is?
EDIT TO ADD: A Papilio Pro plus an audio wing looks like it comes out at £77.80, ex VAT.

Look for "i2s" modules. E.g. there's one for ~20EUR that adds a stereo ADC/DAC (e.g. also usable for the raspberry pi). It has a "i2s" interface which is the canonical way to interface with audio ADCs/DACs. This can easily be connected to any FPGA.

Looks like you could fit 1 J32 32-bit RISC CPU on there with a few gates to spare.

If you want it for (hopefully) christmas, there is also the Papilio Duo Kickstarter: https://www.kickstarter.com/projects/13588168/papilio-duo-dr...

I've been doing digital design for Xilinx FPGAs, as well as IC design, for a few years now and never had any trouble with the Linux toolchain. I can't even imagine switching to Windows and trying to automate the build (not saying it's not possible, it just seems a lot more convoluted).
It's true that smaller vendors like Lattice seldom provide Linux software, but it's also rare to find bigger shops (as opposed to hobbyists) who don't use Xilinx or Altera exclusively, and Linux at that.
