one minute interval timer

To create a test table:CREATE OR REPLACE VIEW v asselect to_date (' 2015-1-1 13:14:15 ', ' yyyy-mm-dd HH24:MI:SS ') as C from DUAL; SELECT * from V;Two date subtraction, get the number of days, multiplied by 24 is the hour, and so on, you can calculate the second, if you want to calculate the month interval, you need to use the function Months_between.The SQL code is as follows:SELECT interval days, number

Article Title: Linux system process interval timer Itimer. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. The Interval Timer (itimer) refers to the

10 pin Single-Chip Microcomputer 2. the time can be modified. What do you think is the usefulness of a timer that cannot be modified? That's a time bomb .. So we need to modify the time. How many buttons are required? Without reusing buttons I think 3 are better. "Ten Minutes", "One minute", and "OK 」 3. Time reminder Reminders are required when the time is up. I have a choppy buzzer, 9 ~ 15 V, sound is hu

This paper illustrates the use and removal of ANGULARJS timer. Share to everyone for your reference, specific as follows: 1. Compared to JS in Settimeinterval and settimeout,angularjs through the interval to achieve the effect of the timer, through the timeout to achieve time delay. $timeout//Implementation is deferred execution $

I. Summary As mentioned in the blog "diy_de2 dm9000a Nic debugging routine series (4) -- TCP/IP implementation based on nichestack protocol stack", when using the system to build the niosii soft core, an interval timer core is required for the uC/OS II system. The interval timer kernel has multiple modes. At that tim

In embedded development, delayed function calls are often encountered. For example, Data Interaction conflicts between nodes must be considered during protocol preparation. The time consumed by each instruction execution on 51 series single-chip microcomputer is known, so the precise delay is easy to implement. In the series processor, the execution of commands adopts the pipeline technology, and the machine cycle parsed by the compiler is unknown in terms of application layer programming. There
