Re: Xilinx FPGA expansion anyone?

Sounds like the concept is well aligned to the RPi aims, viz a low cost platform, that encorages users to get their hands dirty with hardware. In this case whats bing offered is experience in playing with FPGAs, so yes having it so it can be programmed from the Pi is a great idea. Would one be able...

You have to do something with that web page though. That small yellow text on a black background is almost unreadable here. Google Chrome, no zoom, LCD monitor.
I absolutely agree - try here: (it's better but I still need to improve it...)

Re: Xilinx FPGA expansion anyone?

I have an updated specification for the board i'm working on together with a 3D CAD drawing of the board taken from the board development tools - so it's definitely moving on... I need to finalise the bill of materials and get this off to the guys who are going to handle it's manufacture so ai can g...

Re: Xilinx FPGA expansion anyone?

Would be interesting if it had enough gates to say emulate(in hw) some older 8bit and 16bit comps(support chips, cpu, etc.), e.g. Atari 800... A few years ago i'd probably be up for doing that... I wouldn't be surprised at all if someone had already ported something like the 6502 based Atari to VHD...

Re: Xilinx FPGA expansion anyone?

Hi Serac, As far as I know the serial port on the Pi only becomes 'RS232 serial port' with the addition of a external level converter. The serial RS232 port i'm describing on the PiXi board is a dual standard RS232 / RS422 port that includes the voltage level conversion on-board - much like a board ...

Re: Xilinx FPGA expansion anyone?

Thanks John, i'll take a look at those discussions. It was going to be a Spartan 6 but at the time I was able to get a much better price on the Spartan 3 - and it was the 3A. The Spartan 3A is going to be in production for long enough to make such a product last a few years so it potentially offers ...

Xilinx FPGA expansion anyone?

Hi all, Firstly a quick intro… I’m an electronics engineer working in the professional broadcast industry with a fairly significant background in both board-level and FPGA design. I received my Raspberry Pi a little while ago and immediately became interested in developing a simple plug-on board to ...

Re: Introduce yourself!

Hi everyone, I've just registered so this seemed a good place to start... I'm a 40-something professional electronics engineer with passion for innovation, the Pi looked perfect platform for inventing something and I have several plans for it... My background starts with the Atari 8-bit machines (& ...
