dac0832通过ad转换可以产生正弦波和三角波和方波(dac0832 conversion by ad can generate sine wave and triangular wave and square wave)

说明：  在此基础上，设计一种温度测量系统，能够检测温度，并通过按键调整温度的上下限值，若超过该限值，进行报警提示。该系统的硬件子电路主要用Protues仿真软件实现，具体的子电路包括：恒流源电路（TLC2543芯片）、信号放大调理电路（两线制铂电阻PT100）、单片机最小系统（AT89C51）、A/D转换电路、按键电路、显示电路、声光报警器等。该系统的软件电路以C语言为基础，在Keil中实现。最后通过软硬结合，实现电路的各种情况仿真，以此验证电路设计的正确性和合理性。(On this basis, a temperature measurement system is designed, which can detect the temperature and adjust the upper and lower limits of the temperature by pressing the key. If it exceeds the limit, an alarm will be given. The hardware sub circuit of the system is mainly realized by Proteus simulation software. The specific sub circuits include: constant current source circuit (TLC2543 chip), signal amplification and conditioning circuit (two-wire platinum resistance PT100), minimum system of single chip microcomputer (AT89C51), a / D conversion circuit, key circuit, display circuit, sound and light alarm, etc. The software circuit of the system is based on C language and implemented in keil. Finally, through the combination of hardware and software, the circuit simulation is realized to verify the correctness and rationality of the circuit design.)
