MAX7219
介绍一种使用MAX7219实现时钟显示的设计。设计主要由软硬件组成。软件方面，主要针对串行发送、计时中断程序进行编制，实现了串行传输技术的时钟显示。硬件方面，基于MAX7219，采用可在线编程的AT89S51芯片为时钟的CPU，并采用高集成化的串行输入，输出共阴极显示驱动器MAX7219为时钟LED的驱动器。使用串行传输技术大大节省了CPU的IO口，为CPU其他功能的扩展提供了端口(Describes a display using the MAX7219 to achieve the design of the clock. Formed mainly by the hardware and software design. Software, mainly for serial transmission, timing interrupt the program for the preparation, transmission technology to achieve a serial clock display. Hardware, based on the MAX7219, the use of online programming AT89S51 chip to clock the CPU, and high integration of the serial input and output common-cathode display driver MAX7219 LED drive for the clock. Use serial transmission technology saves the CPU IO port, the CPU provides the other functions of the expansion port)

Energy efficiency is the most important design goal
for wireless sensor networks (WSNs). In this paper, we propose
an energy-efficient cooperative MIMO scheme, which
combines energy-efficient LEACH (EE-LEACH) protocol and
cooperative MIMO. We name it as EE-LEACH-MIMO
scheme. EE-LEACH is an improved LEACH algorithm, in
which the network is partitioned to sectors with equal angle for
avoiding the distribution non-uniformity of cluster heads. In
EE-LEACH-MIMO scheme, the location and the residual
energy of each node are considered when the cluster heads for
clustering and cooperative nodes for MIMO system are chosen.
For comparisons, LEACH, EE-LEACH, the simple
cooperative scheme with LEACH and MIMO (LEACHMIMO),
and EE-LEACH-MIMO scheme are simulated. The
result shows that EE-LEACH-MIMO scheme can well balance
the network load, save energy and prolong the network
lifetime
