尽量朝“单片”方向设计硬件系统。系统器件越多，器件之间相互干扰也越强，功耗也增大，也不可避免地降低了系统的稳定性。随着单片机片内集成的功能越来越强，真正的片上系统SoC已经可以实现，如ST公司新近推出的μPSD32××系列产品在一块芯片上集成了80C32核、大容量FLASH存储器、SRAM、A/D、I/O、两个串口、看门狗、上电复位电路等等。 -North Korea as the "single-chip" design direction of the hardware system. System devices more mutual interference between devices are more strong, power consumption is increased, it will inevitably reduce system stability. With MCU with on-chip integration of more powerful, the real system-on-chip SoC can achieve, such as ST"s new PSD32 x x in a series chip integrates exertion nuclear, large-capacity flash memory, SRAM, A/D, I/O, 2 serial port, watchdog, the power-on reset circuit and so on.

AVR硬件设计注意事项,需要在设计中注意-AVRHARDWARE DESIGN GUIDE

红外线遥控器按键检测程序. 通过检测两次下降沿之间的时间差判断接受到的数据位. 已经通过了测试,能够正确区分出32bit数据的遥控器按键键值. 具有数据重发功能,但是数据的重发有点频繁. 使用晶震频率为11.0592MHz,所有定时值都是基于这个频率计算. 占用很少量的CPU时间,使用了外部中断0接受数据,定时器0进行计数, 定时器1作为串口的波特率发生器(Band = 9600).-Infra-red remote control button detection program. By detecting falling edge twice to determine the time difference between the received data bit. Has passed the test, could correctly distinguish 32bit data button remote control key. With data re-issued, but data a bit of re-issued frequent. Zhenyuan frequency of use of crystal 11.0592MHz, all timing values are calculated based on this frequency. occupied by small quantities of CPU time, use the external interrupt 0 to accept data, timer 0 to count, timer 1 as a string port baud rate generator (Band = 9600).

基于AVR单片机的串转并大屏幕汉字显示 开发环境 I-Based on the AVR MCU series and big screen to show the development environment of Chinese Characters I

这是我用C语言写的一个数字钟，他可以实现多种闹钟和秒表功能-This is because I use C language written in a digital clock, he can achieve a variety of alarm and stopwatch functions, etc.

一个75HZ铃流实时检测程序，灵敏度很高，可以用于电话来电铃流检测。-a 75HZ bell flow real-time detection procedures, high sensitivity, can be used for phone calls Chu flow detection.

用3310液晶做的自己做的温度计(51芯片)-3310 make use of their own to do liquid crystal thermometer (51 chips)

控制步进电机正转，如：p3.2正转,p3.3反转,p3.4停止 步进电机接p1.0p1.1p1.2p1.3，正转，反转各3圈，正反快慢功能，是步进机的经典程序。-Stepper motor control is transferred, such as: p3.2 is transferred, p3.3 inversion, p3.4 stop stepper motor then p1.0p1.1p1.2p1.3, is turn, reversal of the 3 lap, both positive and negative speed function, is a classic step process machine.
