IAR for ARM5.4的序列号生成器 Key for EWARM_FULL_ARM540-IAR for ARM5.4 serial number generator Key for EWARM_FULL_ARM540

在使用飞思卡尔单片机DZ60时发现，使用用它内部晶振时，串口无法通信，查其原因并分析后得出的结论是内部晶振误差较大，需要校准，本代码通过使用串口通信来得出晶振校准值，使用该校准值后，串口波特率为9600能很好的通信

用verilog写的跑表程序--Stopwatch program written by verilog.

这是一个总线接口的协议,版本还行,看看吧.-This is a bus interface agreement versions also OK, let"s see it.

本提交代码经过量产的考验，其中含灰尘传感器，CO2传感器，温湿度传感器等传感器的采集，处理，显示的方法，供广大单片机爱好者参考，谢谢！！！！！！

通过键盘设定温度和加热时间。 （2）使用DS18B20采集温度，采用七段数码管显示当前温度和剩余时间，并和设置的温度进行比较。 （3）当温度低于设定值时，通过DAC0832输出电压供给发热电阻RT1,使其温度升高。 -Through the keyboard setting temperature and heating time. (2) The use of DS18B20 collecting temperature, using seven-segment digital tube displays the current temperature and the remaining time, and and set the temperature for comparison. (3) When the temperature is below the set value, the DAC0832 output voltage of the supply of heat through the resistor RT1, so that temperature.

大家用lpc214x，开发usb的朋友，在编好usb前端驱动和固件编程之后，就可用这个pc机端的程序检验自己的usb是否好使。-U.S. used lpc214x, development usb friend that in a good usb drive and front-end after the firmware programming, you can use this pc client machine to test his procedure so that the usb does.

ISP for STR73X 默认情况下, bank0 是映射到地址0x00. 考虑到,IAP程序需存储在bank1,而用户程序需存储在bank0. 因此须使用CAPS工具,将bank1映射到地址0x00. 另外, 在IAP程序运行期间,必须在执行用户程序跳转之前,通过程序将bank0重映射到地址0x00(注:IAP程序已经实现了bank0重映射到地址0x00,用户不需要自己来编写代码).-ISP for STR73X default, bank0 is mapped to address 0x00. Taking into account, IAP process is stored in the bank1, while the user program to be stored in bank0. It is necessary to use the CAPS tool bank1 mapped to address 0x00. In addition, IAP procedure during operation must be in the implementation of user program before Jump through the procedure will bank0 re-mapped to address 0x00 (Note: IAP program has achieved bank0 re-mapped to address 0x00, the user does not need to write their own code).
