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)

Derakane-441-400
DERAKANE 441-400 epoxy vinyl ester resin is a lower styrene-content resin that
has an optimized epoxy backbone and resultant superior thermal properties and
corrosion resistance performance which places it as a type between DERAKANE
411-350 and DERAKANE 470-300 resins. DERAKANE 441-400 resin offers a
superior shelf life compared to conventional vinyl ester resins which provide
additional flexibility to fabricators in storage and handling.
