【摘要】为了克服传统单片机开发过程中存在的硬件成本高、开发速度慢等诸多弊端，介绍了采用EDA仿真软件PROTEUS开发的数控恒流源系统。给出了系统硬件电路设计方案和在Keil环境下开发的主要程序代码。AT89C52单片机控制TLC5615串行D／A转换器输出锯齿形电压信号，此电压信号经电压电流转换电路转换产生稳定的线性电流信号。在PROTEUS环境中完成了软件和硬件的仿真，验证了设计方案的可行性。设计过程简单方便，降低了开发成本，设计效率得到大大提高。%In order to avoid the defects of high hardware cost, slow development rate etc in traditional design of the Single Chip Microcomputer, the system of Digitally Controlled Constant-Current Source Based on PROTEUS, a EDA simulation software, was introduced in this paper. The hardware design project and the primary code designed in the Keil development environment were analyzed. The AT89C52 MCU controls TLC5615 serial D/A converter output sawtooth wave voltage. This voltage signal generated a steady linear current signal via V/I convert circuit, and completed the software find hardware debugging in PROTEUS system. The experiments show that it is real feasible of the scheme of Digitally ControUed Constant-Current Source system. Design process is simple, convenient and it has greatly
