用ATmega8单片机驱动1602液晶显示，-ATmega8 using 1602 single-chip LCD driver,

能够检测温度，并设置报警温度，界面由1602LCD显示-Able to detect temperature, and set the alarm temperature, the interface displayed by the 1602LCD

步进电机的c程序例子,基于单片机的一个例子.-Stepper motor c program examples, an example based on single chip.

Self-tuning PID Controllers ,有需要的朋友可以参考 !-Self-tuning PID Controllers, there is a need of a friend can refer to the reference!

电话机的工作原理,有振铃电路,电话极性保护电路,还有双音多频发送接收电路-Telephone the working principle, has ringing circuit, Phone polarity protection circuit, as well as send DTMF receiver circuit

FreeRTOS，这个比 Real Time Linux 和 eCos 更小的实时操作系统，并且你也不用为这两个大的操作系统弄得头大了。FreeRTOS是一个非常小的实时操作系统，它包含有一个实时的内核及一个内核调制程序。它支持的单片机有 Philips ARM7, TI MSP430, Renesas (Hitachi) H8/S, Atmel AVR, Motorola/Freescale HCS12, Motorola/Freescale ColdFire, 及其他8051的单片机--FreeRTOS, an OS smaller than Real Time Linux and eCos. It is a very small real time operating system. It includes a real time kernel and a kernel configuration program.Its supported SCMs include Philips ARM7, TI MSP430, Renesas (Hitachi) H8/S, Atmel AVR, Motorola/Freescale HCS12, Motorola/Freescale ColdFire, and other 8051 SCMs.

RTC实时时钟例程,可值参考移值使用.好就顶下.-RTC Real Time Clock routine can shift the value of the use of reference values. Good on the top of the next.

基于AT89S52单片机的电子万年历设计制作的汇编程序-AT89S52-based single-chip design of the electronic calendar of the assembler

用c51编的 键盘输入的乘法运算，增加语句可以增加功能-C51 series with the keyboard input of the multiplication to increase the sentence can increase the functional
