一个接收GPS模块接收时间显示在LCD上面 用SW调格林威治+

* 功能：运行RTC进行计时，将所时间值不断的通过串口向上位机发送，并把秒的值输出数码管D1 * 上显示。上位机运行EasyARM软件，在串口发送/接收窗口观察。 * 说明：* 通讯波特率115200，8位数据位，1位停止位，无奇偶校验。-* Function: RTC to run for a time, the time value will be constant upward through the serial-bit machine to send, and seconds values D1* output digital tube display. PC running EasyARM software serial port to send/receive window of observation.* Description:* 115200,8 bit baud rate of communication data bits, 1 stop bit, no parity.

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

x5045有四种功能：分别是上电复位、看门狗定时器、电源电压监控和块锁保护串行eeprom的功能， 该程序通过改变控制寄存器的参数可以实现看门狗定时器监视电压和设置保护rom区，每次复位后 地址计数器都是该区的首地址（个人观点），即断点地址。 问题：其实对该芯片的应用还是很模糊-x5045 four functions : the reduction of electricity, watchdog timer, Supply voltage control and protection block serial eeprom lock function, The procedure by changing the parameters of control register can be achieved watchdog timer and set up surveillance voltage protection rom, After each reset address counter area is the first address (personal view), breakpoint address. Question : In fact, the application of this chip is still very fuzzy! !

PC数字电压表的设计,原理图以及代码,设计文档.此数字电压表的优势在于可以通过串口将测量所得到的电压值传给PC机,这样的话有利用整个数据的采集与分析.上位机采取的是串口通信软件.-PC digital voltage meter design, diagram and code, Design Documentation. This figure voltage meter advantage is through the serial port will be measured by the voltage transmission PC, so is the use of the entire data collection and analysis. PC"s serial port communication software.

very good c program for software
