这个是sbc2410开发板上的通过qt，在触摸屏上控制开发板上的led灯的亮灭。具体操作有一个说明！可以互相交流一下。,This is a development board sbc2410 through qt, in the development of touch-screen control panel of the bright lights led out. There is a specific operation that!

基于51单片机控制的pwm输出，，占空比可调节，负载位led灯，根据led的亮度强弱可判断pwm占空比的大小-Based on 51 MCU-controlled pwm output, duty cycle can be adjusted, the load position led lights, under the led brightness pwm duty cycle can be judged the strength of the size of the

利用QT编写界面，设计一款可视化的软件来演示一些基础实验，要包括LED测试、按键测试、A/D转换测试、PWM蜂鸣器测试-Prepared using QT interface, a visualization software designed to demonstrate some basic experiments, to include LED test, key test, A/D converter testing, PWM buzzer test

这是针对2440开发板，并用QT编写的LED控制的程序。-This program is used to control the LED, mainly is aims at the 2440 development board
