一个可以调试MCS-51指令系统的中文调试软件，此调试软件可以对C51和A51进行编译连接，操作十分简单，而且还可以通过主面版对SFR中的内容进行观察，对学习80C51单片机的学生用十分重要的用途-can debug an MCS-51 instruction in Chinese debug software, this software can debug C51 and A51 to compile links, operation is very simple, but also through the main panels on the content of SFR observe, to learn 80C51 microcontroller with the students the importance of the use of

DIY多功能转换器（已调试通过）。 本原理图可以实现USB/RS232、USB/RS422、USB/RS485接口转换功能。只需安装USB驱动程序即可实现USB转串口的功能，简单方便。另外只需对电路图稍作改动即可实现RS232/RS422或RS232/RS485转换功能。 心动了吗？不如赶快行动，拥有属于自己的五合一的接口转换器吧！-DIY Multi-function Converter (has debug through). The schematic diagram can be achieved USB/RS232, USB/RS422, USB/RS485 interface conversion. Simply install the USB driver can achieve the function of USB to serial, easy and convenient. Also just to make a minor amendment to the circuit can be realized RS232/RS422 or RS232/RS485 conversion. Echocardiography it? Action as soon as possible, with their own-one interface converter吧!
