摘要
本文提出了一种基于CH340T转接芯片设计的单片机编程器。该编程器主要由单片机子系统、CH340T转换系统和供电系统组成。它通过USB接口与PC上位机通讯,用户只需要通过PC上位机GUI的简单操作,就可以实现对STC89C/S51XX/52XX等系列单片机的擦除、编程、校验和加密。经过STC89C52RC等单片机反复测试,该编程器功能稳定、速度快、价格低和易用性强等优点。
This paper presents a design of MCU Programmer based on CH340T adapter chip.The programmer is mainly composed by the microcontroller subsystem,CH340T conversion system and power supply system. It communicates with the host computer via USB connection;users can achieve the erasure,programming,ver ification and encryption of STC 89C/S 51XX/52XX series MCU only by simple operation by a PC GUI on the host compute.After repeated testing on STC89C52RC microcontroller,the programmer has the advantages of stablity,fast,low price and easy of use etc.
