BFGMiner

• Avalon3 nano BFGminer 运行参数

 ./bfgminer \
       -S ICA:/dev/ttyACM0 \
       -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。

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
