题目要求设计一个用于智力竞赛的抢答计时器。主持人按下启动钮，开始抢答，参赛方（八方）看到允许抢答信号后分别按不同的抢答按钮参与抢答。一旦其中一方按下按钮，相应的抢答者编号显示在屏幕上，此时若其他按钮按下均无效。若无一人按下按钮，则抢答结束（以后按抢答无效）。③ 若温度值越界则进行声（蜂鸣器）、光（发光二极管）报警； 说明：界限值是自行设定的（26C），其所对应的数字量为十六进制数（0180H）。 （2）使用DS18B20采集温度，采用七段数码管显示当前温度和剩余时间，并和设置的温度进行比较。 （3）当温度低于设定值时，通过DAC0832输出电压供给发热电阻RT1,使其温度升高。 （4）使温度恒定在设定温度附近，时间到了停止加热，并提示操作完毕。 -In the STAR ES598PCI veneer development machine to realize oven temperature and time control functions. Design requirements: (1) through the keyboard to set the temperature and heating time. (2) The use of DS18B20 collecting temperature, using seven-segment digital tube displays the current temperature and the remaining time, and and set the temperature for comparison. (3) When the temperature is below the set value, the DAC0832 output voltage of the supply of heat through the resistor RT1, so that temperature. (4) to enable the temperature constant at the set temperature near the time to the cessation of heating, and prompt action is completed.
