Really really interesting post. I tried an uart communication with another tool fpga. GitHub is home to over 20 million developers working together to host and review code, manage projects, and build miners together. This is altera to prevent damage to your valuable chip if you don't provide an appropriate cooling solution. Bitcoin can't perform that action at this time. If working correctly, 'mine.
Project is fully functional and allows mining of Bitcoins both in a Pool and Solo. Be sure to select the correct one, because the hardware effects the location of your pins, which you will need in the clock pin step. At least that is what you can get with this thing: November 5, Run Powerplay power analyzer tool and set it with the cooling system you have. Repeat steps 1 through 7 for subsequent uses.

Powered by SMF 1. Miners the instructions provided by altera program-fpga-board script. I can bitcoin 8 of these in a cluster here: At this stage it would fpga possible to download the compiled design to the FPGA, but it would be lost as soon as power to the board is removed. Sister projects Essays Source. It also supports Namecoins.
At this stage it would be possible to download the compiled design to the FPGA, but it would be lost as soon as power to the board is removed. From the File menu select Convert Programming Files and set the following parameters:. If there is an entry for the. This is straightforward enough and covered in the provided instructions. This can be compiled with:. The DE0-Nano and Raspberry Pi both use 3v3 logic levels, however, the instructions still recommend using optoisolators between the two.
I went for a much more direct connection between the boards, placing 1K resistors in series with TX and RX just to give some measure of protection. Since this was my first attempt at Bitcoin mining I also added LEDs so that I could at least confirm when data was being exchanged.
Following which the minelive2. After a few successful matches we can then check the mining pool dashboard to see that these have been registered. The estimated speed shown in the dashboard screenshot above should be disregarded as the miner hadn't been running for very long and this is based on insufficient data. I left the DE0-Nano clock speed set at the fpgaminer default of 40MHz, which supposedly gives a performance of 6.
I find Bitcoin fascinating and although I have no intention of trying to make a fortune with the cryptocurrency, there is something strangely compelling about Bitcoin mining. When starting out I didn't give a second thought to increasing the FPGA clock speed, but now I find I'm tempted to put a heatsink on the FPGA, double the clock speed or more and try out higher performing designs. If money is not the motivation, then what is? Well, simple geeky fun, the pursuit of amassing a volatile stash of what may amount to absolutely nothing, and playing a very small part in what is very likely to be a fun ride however it turns out.
Open source hardware and software! Fellas i need to exchange btc to payeer, do you think this service https: Great article, would it be possible to use multiple FPGAs, or would you need separate serial devices for each one on the Pi? After a couple of days trying and debugging the mining software on the RPi i found the solution. The little correction for your guide is that you need a proxy on your RPi which converts the getwork protocol to the stratum.
Infos on this site: Try changing this to "stratum. I haven't had my setup running for quite a while now DE0-Nano being used for other things , so my memory is a bit hazy, but I seem to recall trying a few different hosts before I got it to work the software uses a deprecated pooling protocol, so this meant that not as many servers support it.
If you're using BTC Guild, I'd also suggest trying the connection details I used, as can be seen in the screenshot host: Andrew I checked what you mentioned, but without success. The RPi is set up like provided instructions on github. I tried an uart communication with another tool e.
The internet connection is present verified with ping to stratum. Please feel free to give me feedback, suggestions, critiques, and of course to submit Pull requests. Compatible Board and only purchase currently required: This is not the only supported FPGA board, but it is the only board with mining binaries and instructions currently available. The software can be manually compiled for many different chips Altera and Xilinx and boards. More pre-built binaries and instructions will be made available as time allows.
News and Updates June 2nd, - Flexible Unrolling Added Thanks to the patch submitted by Udif, the code now supports a configurable amount of loop unrolling. The original design was fully unrolled, with total round modules. This makes the design smaller, at the equivalent cost of speed, which should allow it to run on many more FPGAs. Then just compile and program! I made little to no modification to their code for this first commit. If you appreciate their hard work on this Open Source project, please send them your thanks and donations!
I will modify the first post in this thread to include the same list As it wasn't mentioned before on the first post, I am mentioning here that makomk made improvements to my base Verilog code. These changes improved both the overall performance of the design, and its area consumption, allowing the design to fit on a smaller, cheaper EP4CE75 chip.
The Altera Tcl Mining Script has just received a massive update. No more need to edit mine. Pool information has been moved to a config.
No more dependency on TclCurl, so the script should be Linux friendly now. And best of all, the console output has been cleaned up to look like poclbm. Here is the project. As an additional surprise, this code includes support for the Kintex's on-die temperature sensor. Temperature readings are reported over UART, allowing external software to monitor the chip. In the future I will add automatic shutdown on over-temp conditions. Contributors These fellows have contributed to this Open Source project in various ways, and deserve recognition.
