TI公司模拟电路专家撰写的顶级运算放大器设计指南，可惜是英文的。不过还是值得推荐...

atmel工业级芯片手册，虽然过时，但是很实用，非常稳定。内置512k RAM。-Atmel chip industrial grade manual, although outdated, but very practical, very stable. Built-512k RAM.

这是我自动答录机的源代码。它可以控制 8 路继电器输出通过 GSM 网络。首先，当你调用它时，它将比较拨入号码与 sed 卡中存储的数字。如果它们匹配，它会回答，然后你会听到一个声音说你好。唧唧歪歪

nuclues 内核源代码已经在arm7-9 上作了移植

1. T0_ASM.rar, (带中文注释的C51语言例程), 利用定时器0中断实现LED灯的简单控制。 2. T0_C51.rar, (带中文注释的51汇编语言例程), 利用定时器0中断实现LED灯的简单控制。 两个同样功能的timer0中断程序都在MCU51-63K仿真器下通过实验。-1. T0_ASM.rar, (with Chinese comments C51 language routines), use of the timer 0 interrupt LED lamps to achieve a simple control. 2. T0_C51.rar, (with English Notes 51 assembly language routines), use of the timer 0 interrupt LED lamps to achieve a simple control. Two same functions Timer0 interrupt procedures are MCU51-63K emulator through the experiment.

这是一个用于创建多线程的程序，用法简单，内有例子，开消非常小，适合用于较低性能cpu上如51，arm7-This is a used to create multi-threaded program, usage is simple, there are examples, the extinction is very small, suitable for low performance on the cpu, such as 51, arm7
