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!

单一灯的左移右移分别接在单片机的P1.0－P1.7接口上，输出“0”时，发光二极管亮，开始时P1.0→P1.1→P1.2→P1.3→┅→P1.7→P1.6→┅→P1.0亮，重复循环-A single light, respectively, shifted to right then left at P1.0-P1.7 microcontroller interface, the output " 0" when the bright light-emitting diode, the beginning of P1.0 → P1.1 → P1.2 → P1. 3 → ┅ → P1.7 → P1.6 → ┅ → P1.0 Liang, repeat cycle
