The OReilly Struts book (title not set yet) will be available sometime in the 3rd quarter of 2002. Published by OReilly, this book covers both Struts 1.0 and 1.1. The beta or draft chapters are being made available for download to facilitate an early public review process for the material.

将数字时间转换为英语口语表达形式，控制台形式。其实核心代码为一个类，可以自己修改输出形式。 比如输入 8 15 10 45 5 30 2 20 2 40 0 0 就能转换为： It s twenty past eight It s a quarter past eight It s a quarter to eleven It s half past five It s twenty past two It s twenty to three 注意： 输入 0 0 后结束并显示结果 方式为每行两个数，中间用空格空开 第一个数0到12表示小时，第二个数0到59表示分钟

I can remember buying my first electronic calculator. I was teaching a graduate level statistics course and I had to have a calculator with a square root function. Back in the late 1960s, that was a pretty high-end requirement for a calculator. I managed to purchase one at the “educational discount price” of $149.95! Now, I look down at my desk at an ATmega2560 that is half the size for less than a quarter of the cost and think of all the possibilities built into that piece of hardware. I am amazed by what has happened to everything from toasters to car engines. Who-da-thunk-it 40 years ago?

该步进电机驱动器又称为EasyDriver，EasyDriver能够为两级步进电机提供大约每相750mA（两极一共1.5A）的驱动。它默认设置为8步细分模式（所以如果你的电机是每圈200步，你使用EasyDriver时默认为每圈1600步），更多细分模式可以通过将MS1或MS2两个接脚接地进行设置。这是一种基于Allegro A3967驱动芯片的细分断路器。对于此设计的完整规格，请查阅A3967的参数表。它的最大每相电流从150mA到750mA。可以采用的最大驱动电压大概是30V，其中包括板载5V的调压器，所以只需要一个电源。质优价廉，这玩意儿只要十几美元，比你自己制作电路板更便宜。步进电机驱动器设计特色：· A3967 Microstepping Driver· MS1 and MS2 pins broken out to change microstepping resolution to full, half, quarter and eighth steps (defaults to eighth)· Compatible with 4, 6, and 8 wire stepper motors of any voltage· Adjustable current control from 150mA/phase to 700mA/phase· Power supply range from 6V to 30V. The higher the voltage, the higher the torque at high speeds
