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>
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。

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。
