Scan-button
- 扫描按键,赋值了16个键,按一个显示相应的数字-Scan button, the assignment of the 16 key, press the corresponding number of a display
irsen
- 红外遥控程序,扫描按键的发送,判别键值得-ir output
keyboard-program
- 本程序直接采用分时扫描法,本板设计了5个按键,分别接于P13-P17引脚,按键都以接0方式触发(即按键另一脚接GND)-The program directly using the time-scan method, the board design 5 buttons, respectively, then the P13-P17 pin, trigger keys way to pick 0 (that is the key to another pin GND)
keyscan
- 用尽可能少的IO口扫描尽可能多的按键的思路-As little as possible IO port scan as many key ideas
ch451dispay
- CH451键盘扫描显示程序代码。可扫描数码管显示和键盘按键。-Internally, a common process of every XIM is to translate keyboard scan code into keycode and then to keysym, by calling XKB, whose process detail has been described in previous sections
VHDL-flutterfree-counter
- 本实验主要完成的实验是完成4×4键盘扫描的,然后获取其键值,并对其进行编码,从而进行按键的识别,并将相应的按键值进行显示。-This experiment is to complete 44 experiments done keyboard scan, and then get their keys, and encode to carry identification keys, and the corresponding key value to be displayed.
anjian
- 扫描键盘和数码显示实验,把按键输入的键码在六位数码管上显示出来-Scan the keyboard and digital display experiment, the key input key code in six digital tube display
e
- 基于51单片机的简易电子琴,能利用所给键盘的1,2,3,4,5,6,7,8八个键,能够发出7个不同的音调,而且有一个按键可以自动播放歌曲,要求按键按下时发声,松开延时一小段时间,中间再按别的键则发另外一音调的声音,当系统扫描到键盘按下,则快速检测出是哪一个按键被按下,然后单片机的定时器启动,发出一定频率的脉冲,该频率的脉冲经喇叭驱动电路放大滤波后,就会发出相应的音调。如果在前一个按下的键发声的同时有另一个按键被按下,则启动中断系统。前面的发音停止,转到后按的键的发音程序。发出后按的键的音调。-5
LED-clock
- 定时器做LED动态扫描程序,可防止按键时显示灭~~ -LED clock uchar code a[10]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07, 0x7f,0x6f}
