MC68340驱动TNT4882，实现GPIB接口通讯(TNT4882 in an MC68340 System)

超声波模块制作了一个测距装置，HC-SR04自身不带温度补偿功能，所以加上一个使用DS18B20做的温度测量模块。整个系统包括：51单片机最小系统，超声波测距模块、温度测量模块、液晶显示模块。(The ultrasonic module has made a distance measuring device, HC-SR04 does not have temperature compensation function, so add a temperature measuring module using DS18B20. The whole system includes 51 single chip microcomputer minimum system, ultrasonic ranging module, temperature measurement module and LCD module.)
