四人抢答器，包括主持人清楚按键，抢答后屏蔽其他三人的继续抢答，同时答题时间开始，答题时间三档可调。时间到后蜂鸣器发声，指示灯亮起。

共两个文件，一个是对网络芯片W5500进行控制的master spi接口，另一个是w5500命令控制逻辑，命令格式按照w5500芯片的要求，分为地址段，控制段和数据段进行统一控制。此外提供w5500芯片初始化及读写控制流程图。(A total of two documents, one is the master SPI interface for network control chip W5500, the other is a w5500 command control logic, command format in accordance with the requirement of w5500 chip, divided into address segment, unified control and data segments. In addition to provide w5500 chip initialization and read and write control flow chart.)

VHDL实现SPI功能源代码 -- The SPI bus is a 3 wire bus that in effect links a serial shift -- register between the "master" and the "slave". Typically both the -- master and slave have an 8 bit shift register so the combined -- register is 16 bits. When an SPI transfer takes place, the master and -- slave shift their shift registers 8 bits and thus exchange their 8 -- bit register values.-SPI realize the functional VHDL source code The SPI bus is a 3 wire bus that in effect links a serial shift register between the

1 前大灯可以随意打开和关闭； 2 当汽车左转弯的时候，前左转向灯闪烁，同时左后灯的3盏灯由右往左闪烁； 3 当汽车有转弯的时候，前右转向灯闪烁，同时右后灯的3盏灯有左往右闪烁； 4 当汽车减速或紧急刹车的时候，左后灯和右后等同时闪烁； 5 当汽车在左转弯的同时减速，则前左转向灯闪烁，左后灯的3盏灯由右往左闪烁，同时右后灯都点亮。 6 当汽车在左转弯的同时减速，则前右转向灯闪烁，右后灯的3盏灯有左往右闪烁，同时左后灯都点亮。 -a former headlamps can be opened and closed at will; 2 when the vehicle made a left turn when the former left to lights flickered. Left lights while the three lights flashing from right-go left; 3 when the vehicle is making a turn when a right turn to the former lights flickered. Right after the lights while the three lights are blinking right and left; 4 when the vehicle deceleration or when the emergency brake, Left and right after the lights blink, and so on; 5 when the vehicle made a left turn at the same time to slow down, and then to the left before the lights flickered. Left lights three lights flashing from right-go left, right after the lights are lit. 6 when a car made a left turn at the same time to slow down, and then right before the lights to flick
