用传输矩阵法计算一维光子晶体的带结构的程序,用matlab所编,文件解压后,程序写在word文档中,并附有在matlab下画的图,本人感觉非常有用-use of the transfer matrix method one-dimensional photonic crystal with the structure of the program, prepared by Matlab. unpacks the files, procedures written in word document, together with the painting under Matlab plans, I feel very useful

PWM 控制 LED 灯渐亮渐灭程序 适用 ME300B 开发系统 利用定时器控制产生占空比可变的 PWM 波 按K1，PWM值增加，则占空比减小,LED 灯渐暗。 按K2，PWM值减小，则占空比增加,LED 灯渐亮。 当PWM值增加到最大值或减小到最小值时，蜂鸣器将报警。-PWM control of LED lights getting brighter gradually eliminate procedures apply ME300B development system the use of timer control which produces a variable duty cycle PWM wave by K1, PWM value is increased, then the duty cycle decreases, LED lights dimming. According to K2, PWM value is reduced, then the duty cycle increases, LED lights gradually brighter. When the PWM value is increased to maximum or reduced to minimum, the buzzer will alarm.

用来计算一些很简单的整数的四则运算（没有括号的)-Used to calculate the number of very simple integer four operations (without brackets)

汇编程序调试软件,较好的汇编程序调试软件，是你编程的好帮手-Assembler debugging software, a better compilation of program debugging software, you are programming a good helper

it can help you use C++ program we

1) 东西方向车辆放行20秒钟。即东西方向的绿灯和南北方向的红灯同时点亮20秒钟； 2) 20秒钟后，东西方向的黄灯闪烁2秒钟，以警示车辆将切换红绿灯。此时南北方向仍维持红灯点亮。在南北方向亮红灯期间，在2位数码管上显示计数值（每秒减1），从20减至01。 3) 东西方向的黄灯闪烁2秒钟后，转为南北方向放行20秒钟。即东西方向的红灯和南北方向的绿灯同时点亮20秒钟； 4) 南北方向放行20秒钟后，转为南北方向的黄灯闪烁2秒钟，以警示将切换红绿灯。此时东西方向仍维持红灯点亮。 5) 南北方向的黄灯闪烁2秒钟后，再转为东西方向车辆放行20秒钟。如此循环重复。 -1) direction vehicle release 20 seconds. What is the direction of red and green light at 20 seconds, 2) 20 seconds later, the yellow lights flashing warning vehicles with 2 seconds, switch to the traffic lights. This is still remain red light north-south direction. In the south during the red light, in the direction of the digital display tube of 2 per plan (minus 1), from 20 to 2001. 3) the yellow lights flashing direction to 2 seconds later, the south direction release 20 seconds. What is the direction of the north-south direction of red and green and light 20 seconds, 4) north-south direction after 20 seconds to release the north-south direction, yellow lights flashing warning, with 2 secon
