Configrations

  • LPC11u14
 Clock Crystals        48.000 MHz
  • A3233
 Clock Crystals        24.000 MHz

USB: 29F1:33F1

Schematics

BFGMiner

  • Run under Linux
 ./bfgminer \
       -S ICA:/dev/ttyACMx \
       -o stratum+tcp://stratum.ozco.in:80 -O mikeqin.avalon:1234 \
       --set-device ICA:baud=115200 \
       --set-device ICA:reopen=timeout \
       --set-device ICA:work_division=1 \
       --set-device ICA:fpga_count=1 \
       --set-device ICA:probe_timeout=100 \
       --set-device ICA:timing=0.22 \
       --api-listen \
       2>log
  • Run under Windows
 bfgminer.exe ^
       -S ICA:\\.\COMn ^
       -o stratum+tcp://stratum.ozco.in:80 -O mikeqin.avalon:1234 ^
       --set-device ICA:baud=115200 ^
       --set-device ICA:reopen=timeout ^
       --set-device ICA:work_division=1 ^
       --set-device ICA:fpga_count=1 ^
       --set-device ICA:probe_timeout=100 ^
       --set-device ICA:timing=0.22 ^
       --api-listen ^
       2>log

 备注：timing详见bfgminer的README，如果当前配置的频率是400MHz,则Hashrate=400*11.8=~4Gh/s
 <math>\mbox{timing} = \frac{1}{4\times 10^9}\times 10^9</math>
  • BFGMiner MHS Cur计算
 MHS Cur = Diff1 Work * (Difficulty Accepted/(Difficulty Accepted+Difficulty Rejected+Difficulty Stale)*60/(Elapsed)*71582788/(1000000)
 所有的信息可以通过./bfgminer-rpc -o summary获取。
 注：如果Difficulty Accepted+Difficulty Rejected+Difficulty Stale = 0，则Difficulty Accepted/(Difficulty Accepted+Difficulty Rejected+Difficulty Stale) 取1。
  • BFGMiner release from luck.dashjr

Cgminer for Avalon nano

  • Cgminer（Icarus）compile guide
 sudo apt-get install libudev-dev 
 ./autogen.sh && ./configure --enable-icarus && make
  • Cgminer（Icarus）Run params
 ./cgminer \
       -o stratum+tcp://stratum.ozco.in:80 -O mikeqin.avalon:1234 \
       --icarus-options 115200:1:1 \
       --icarus-timing 0.22 \
       --api-listen \
       2>log
  Note：Please add 01-cgminer.rules to your udev rules before you run.

Windows GUI

背景介绍

* 我们的设备： 针对消费类电子的 USB 设备，尺寸比一般U盘会大一些。
* 后台／命令行的程序已经做完成，我们需要做一个展示的界面。
* 展示界面：
    一个状态界面，一个配置界面。
    配置与状态必须使用后台程序的 Socket API 来通信。
* 参考资料
    比特币挖矿入门 https://bitcoin.org/zh_CN/faq#what-is-bitcoin-mining
    一些常见USB挖矿机的使用方法

    http://rdmsnippets.com/tag/install-block-erupter-on-windows-7/
    http://www.usberupter.com/how-to-mine-bitcoins-using-usb-stick/

要求

* 时间要求：3周
* 支持 MS Windows 7/8
* 界面参照 360 随身 WiFi 的界面
* 在主页上增加广告推送的地方，用户可以接受。
* 简单的安装程序（需要安装1.驱动或者相应的库(libusb)；2.后台程序；3.界面主程序）
