8051c 的一个Crc 算法分析

enc28j60的驱动， 通过ping命令来测试enc28j60是否连同 -enc28j60 drive through ping command to test whether or not together with enc28j60

ATMEL ARM7的一款芯片应用实例,可以在IAR上面运行-ATMEL ARM7 application example of a chip can run IAR above

一份非常完整的51单片机与P/S2键盘的通信程序，含有大量注释，不错的。-A very complete 51 SCM and P/S2 keyboard communication program, containing a large number of comments, good.

单片机51系列的122*32的某液晶驱动程序-MCU Series 122 51* 32 in a LCD driver

0-99的计数器，使用AVR128单片机制作，从0开始记数到99自动清0，用数码管显示-err

在PIC上使用5个口线产生DTMF信号-use five lines I have DTMF signals

一款应用在客运系统的LED导向屏程序，采用汇编语言编写，欢迎相关人员参考-Used in a passenger transport system LED screen-oriented procedures, the use of compiled languages are welcome to the relevant reference

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.

C8051F340在应用中读写FLASH，我自己严格按照数据手册写的，在网上找了半天都没有的-C8051F340 in the application to read and write FLASH, my own data in strict accordance with the written manual, look online for a long time there was none

该设备可以循环检测24节2V6V12V蓄电池组，测量精度达0.05 ，测量结果通过RS485方式上传至主监控。采用MODBUS通讯协议。-The device can loop detection 24 2V 6V 12V battery, measurement accuracy of 0.05 , the measurement results through the RS485 upload to the main control means. Using MODBUS communication protocol.
