用IO口模拟串口

The books for Designing Embedded Communication Software from CMP Books. (Web Version)

A simple preoteus based design to display the characters typed int the keyboard into LCD using UART of 8051.Plz make sure that TTL to RS232 is inserted in between the microcontroller and virtual terminal which is not shown in the design.

Un oscilador LED en ColdFire

点阵单位通常都在任何一个的5x7或8x8的发光二极管矩阵。这些LED连接在矩阵，使得每个LED的阳极或阴极是常见的每一行中。换句话说，在一共阳极LED点阵单元，每个LED行将其所有阳极在该行的有线在一起。 LED的阴极将全部连接在一起在每列中。这样做的原因将很明显很快。一个典型的单一颜色的8x8点阵单位将有16个引脚，8为每个行和8为每一列。的原因的行和列都连接在一起，是尽量减少所需的引线的数量。如果不是这种情况下，一个单一的颜色的8x8点阵单元将需要65管脚，一个用于每个LED和一个共同阳极或阴极连接。通过布线的行和列在一起，只有16个引脚必需的。

该压缩包为ARM S3C44B0的源代码，含有5个程序。分别为按键控制LED,PWM脉冲宽度调制,RTC实时时钟，UART串口通信，DMA直接内存存取等5个实验的源代码。代码以C语言为主，辅以部分ARM汇编指令。该实验开发平台为S3C44B0板，开发工具为ADS1.2.-The package for the ARM S3C44B0 compression source code, which contains five procedures. Were keys to control LED, PWM pulse width modulation, RTC real time clock, UART serial communication, DMA direct memory access, such as five experiments the source code. Code to C language, supplemented by some ARM compilation directives. The experimental development platform for S3C44B0 boards, development tools for ADS1.2.
