说明：  描述了FLASH的读写操作 特别针对单片机的读写 FLASH类型为S29GLXXN写列(Described FLASH read and write operations, especially for the microcontroller to read and write FLASH type S29GLXXN write columns)

51单片机常用到的C语言和汇编小程序，便于模块化设计和参考。(51 single-chip common to the C language and assembly of small programs, modular design and ease of reference.)

基于430的AD9954驱动程序，单频，FSK等全有。(430 AD9954 driver, single-frequency, FSK, such as whole.)

本人自己编写的电子贺卡程序，带有音乐播放，和12864的图像显示(I have written an e-card program with music playback, and image display 12864)

stm32版本的can通信的接收与发送例程，扩展帧方式(Receiving and sending routines of STM32 version can communication, extended frame mode)

使用IO口模拟I2C时序，包括主机、从机时序。(Using IO port simulation I2C timing, including the host, the machine timing.)

类似电脑键盘组合按键触发的功能。利用51单片机实现。有两个独立按键，当把两个独立按键都按下后，蜂鸣器发出“滴”的一声后就停。直到松开任一个按键后，才能重新进行下一次的组合按键触发。(Similar to the function of the keyboard combination of keys. The use of 51 single chip microcomputer. There are two independent buttons, when the two independent buttons are pressed, the buzzer issued a drop of sound after the stop. Until after the release of any key, the next combination of keys can be re trigger. )

C语言编写msp430x44x完成红外测温程序，DA采用AD420完成(C language msp430x44x complete infrared temperature measurement process, DA completed using AD420)

STM32 USB IAP（STM32 DFU），STM32F10X usb升级程序的程序，以及测试程序，还包括dfuse安装软件和使用说明。在刚开始进行stm32 usb升级程序的过程中，网络的很多资料都不完整，错误的很多，自己也遇到了一些问题，话费不少时间，在成功完成此功能后感觉很有必要分享出来，减少大家开发stm32 usb iap功能的时间。(STM32 USB IAP（STM32 DFU）and test program)
