硬件TCPIP协议栈芯片W5300的使用例子代码,该芯片内部通过硬件实现了TCPIP协议栈,可减少CPU运行协议栈的开销.(Hardware TCPIP protocol stack chips W5300 examples of the use of code, the chip hardware implementation of the internal adoption of the TCPIP protocol stack can reduce the CPU overhead of running the protocol stack.)

The LED clock consists of 60 LEDs which are placed circular around a common analog clock. The LEDs are used to display the seconds. Essential part of this circuit is the LED driver MAX7219 from Maxim. A datasheet is available on Maxim s homepage. The clock is controlled by the microcontroller AT89C2051 from Atmel. This microcontroller is clocked at a frequency of 12 MHz from which results a time base of 1 microsecond. Via software dividers one clock impulse per second is generated which is used for updating the LED display.
