使用LPC2131控制KM12864液晶显示屏实现绘图功能

STM32是以Cortex-M3为核的处理器，该例程介绍STM32下如何对串口进行操作。串口是最基本的调试输入输出接口。-Cortex-M3 based STM32-core processor for the routine introduction STM32 how to operate on the serial port. Serial debugging is the most basic input-output interface.

AVR 模拟USB低速率通讯的例子,里面实际已经有应用于编程器-AVR emu USB low-speed communication example

应用背景通过了解DHT11温湿度传感器模块的驱动开发能够很快的掌握linux系统下的驱动开发流程。该实验代码能够为驱动开发的学习提供很好的指导。该驱动应用于s3c2440芯片的开发平台。关键技术dht11温湿度传感模块，通过GPIO口与嵌入式开发板连接。在拥有linux内核的系统中编辑dht11驱动程序，使开发板能够显示dht11传感器收集到的实时数据。通过这个过程来熟悉嵌入式系统下的驱动开发流程。

我在使用陈明计先生写的small RTOS和51单片机做过几个小项目，起初都很好，开发变的容易了，程序变的容易修改。后来随着任务个数的增多，RAM很快就不够用了。51系列的芯片内部RAM普遍都是256个,很难找出1024个字节RAM或更多，而价格又合适的。记得上一次我没有办法被迫使用了64K flash内部带768字节的XRAM的51芯片，而我根本用不到那么多flash。-I use Mr. Chen Mingji written small RTOS and 51 MCU done several small projects at first were very good to develop easy to change the program become easier to modify. Subsequently, the increase in the number of tasks, RAM is not fast enough. 51 series of chip RAM are generally 256, it is difficult to find 1024 bytes of RAM or more, while prices will be appropriate. I remember the last time I had no way forced to use a 64K flash with 768 bytes of internal XRAM of 51 chips, and I will never use that much flash.
