SmallRTOS51key
- 这是Small RTOS 51 DP－51下载仿真实验仪上编写的一个键盘驱动例子。在DP－51下载仿真实验仪上运行本程序后，有两个发光二极管每秒闪动一次。当按下某个按键时，LED数码显示器会显示相应的键值。 注意:(1)在KEIL C51 工程中,我已经把输出文件目录设在e:\\temp中,您可以在Project->Options for Target \"Target 1\"的output页点击Select Folder for Objects...和Listing页点击Sel

- 利用8253实现闪烁灯效果，并最终通过键盘输入指定时间实现定时闪烁，同时利用七段数码管倒计时辅助显示闪烁时间，实现定时设定功能。比如：按下键盘9号键，则LED灯开始每秒闪烁一下，9秒后停止闪烁，实现定时闪烁；同时数码管从9开始倒计时显示辅助显示闪烁时间。-The use of 8253 to achieve a blinking light effect, and ultimately to achieve a specified time by the regular keyboard in
nand_read
- 本源码是基于S3C—6430的ARM11嵌入式开发板的NAND FLASH程序的编写。NAND写回速度快、芯片面积小，特别是大容量使其优势明显。页是NAND中的基本存贮单元，一页一般为512 B(也有2 kB每页的large page NAND FLASH)，多个页面组成块。不同存储器内的块内页面数不尽相同，通常以16页或32页比较常见。块容量计算公式比较简单，就是页面容量与块内页面数的乘积。根据FLASH Memory容量大小，不同存储器中的块、页大小可能不同，块内页面数也不同。例如：8 MB
