Brief Introduction
1. Add 24hour time quantum control feature. The program can auto set the frequency at different time quantum. In the noon, the ambient temprature is high, so ASIC should run at a low speed for less heat generating. On the contrary, the Asic may run at a high speed in the evening.
        Usage Method：
      a. In the system label page，configure the time zone of your country
        b. In the Cgminer Configuration page, 24hour Time-zone Control configuration section, configure the start time, end time and the corresponding chip requency.
      c. If you want to enable the Time-Zone configuration, remember checking the check-box.

2. For Avalon2.5 and avalon3, add the feature that Chip Freqency and Chip Voltage auto match each other. When fix the frequency, the firmware will auto tuning the chip voltage to the lowest value which the chip can work well with. When fix the voltage, the firmware will auto tuning the chip frequency to the highest value which the chip can work well on.
        Usage Method：
      a. Method-1： In the “Cgminer Configuration” page，set the freqency you want in the “Chip Frequency” text box，and set 0 (zero) in the “Chip Voltage" text box. And then, on the premise of machine running normally, the firmware will set the chip voltage as low as it can.
      b. Method-2： In the “Cgminer Configuration” page，set the voltage you want in the “Chip Voltage” text box，and  set 0 (zero) in the “Chip Frequency” text box. And then, on the premise of machine running normally, the firmware will set the chip frequency as high as it can.
      c. Method-3： Set the tow value "Chip Voltage" and "Chip Frequency” simultaneously. This is the old method which will not save power.
     Note: The feature-1 and feature-2 can be used at the same time.

3. Fix the bug that NTPD sync failed cause the system halt and waiting.

4. Fix the bug that system can't run when you set a unsuited frequncy. Now you can set any freqency between 256 - 2000, and the program will tune it.

正好这里有个avalon 2代矿机的固件 “按时间段自动控制的 Avalon矿机的 WR703n 固件” 。
芯片，硬件，软件捆绑推！O(∩_∩)O哈哈~

Avalon3 的还在内测，暂时没敢放出来。不过很快就会出来啦！

有什么建议或者使用心得可以分享啊！^_^

我一个朋友的用法是：跑吵到家里的小孩，所以晚上跑的频率低，这样风扇声音会小一些。白天可以跑高一点。

反正根据需求，用法有很多种的。

简介：
1. 按时间段分别设置矿机运行的频率，到时间点后自动切换，不需要人工干预。例如：夏天中午环境温度较高，为了安全，矿机可以运行在较低的频率。晚上环境温度下降，矿机可以再自动切回较高频率。
        使用方法：
        a. 先在system标签页，将时区改成当地时区，中国的话选择Timezone 为 Asia/Shanghai
        b. 在Cgminer Configuration 标签页的24hour Time-zone Control配置 时间段的起始和终止时间点，以及相应的运行频率。
        c. 一共提供4组时间段，可以分别单独配置和使能。要使用该时间段的话，记得把“小勾”勾上才能生效。

2. 针对avalon2.5 和 avalon3 的机型，增加了电压和频率自动匹配的功能。当指定电压时，该固件会在工作稳定的前提下尽可能调高频率，从而使能效最优；当指定频率时，该固件会在工作稳定的前提下尽可能降低电压，从而最节省功耗。
      使用方法：
      a. 方法一： 在 “Cgminer Configuration” 标签页，“Chip Frequency”项填入要设置的频率，“Chip Voltage”项填“0”（数字零）。这样机器会在工作稳定的前提下尽可能降低电压，从而最节能。
      b. 方法二： 在 “Cgminer Configuration” 标签页，“Chip Voltage”项填入要设置的电压，“Chip Frequency”项填“0”（数字零）。这样机器在工作稳定的前提下尽可能调高频率，从而使能效最优。
      c. 方法三： Chip Voltage 和 Chip Frequency” 都指定为你想要的值，该方式和传统方式一样，没有节能效果。
     注意：目前按时间段自动控制的功能和节能的功能可以配合使用，但是只支持指定频率的方式（使用时记得设置电压为0）。（后续版本会增加指定电压的方式）

3. 修复了由于网络原因，NTPD 校时服务导致矿机不能启动的bug

4. 修复填错频率不能运行的bug。老版程序所配置的运行程序必须是填固定的一些频率值，否则矿机不工作。改进后，avalon2和avalon2.5填256 - 1800之间任意一个频率，avalon3填300-550之间任意一个频率，矿机都能正常工作。
