The create procedure proc1 (OUT s int) process in mysql is simple, but the 1307 error occurs during the import process, let's take a look at the solution to this problem. Test The Code is as follows: Copy code Create procedure test1 (in a int) // create; procedure stored procedure ()Begin // startSelect * from test where id = a; // here is the statement of the stored procedureEnd; // end// Note: Delimiter must be changed

RTC is a relatively common part of the current device, and many devices need to look at the time. RTC Real-time clock has been integrated in a number of microcontroller, before also dedicated clock chip, now the CORTEX-M3 core includes this part. Unlike previous NXP's ARM7 cores, the LPC1768 clock source is provided only by the 32K clock source, which is to be noted, and the other is consistent with ARM7.

http://bbs.chinaunix.net/forum.php?mod=viewthreadtid=3637782 Linux RTC Driver is relatively simple, it can be used as a normal character device, or a misc device, or a platform device, which is not related, mainly to rtc_ops this file operation structure of the member population, Here are mainly related to two aspects more important:1. There are two kinds of clocks, such as hardware clock and system clock, in Linux. The hardware clock is

Absolute timing function (seconds, minutes, hours, days, months, and years) ? Relative timing Function ? Supports 12-hour/24-hour Mode ? Automatically recognize a leap year ? Weekly counter ? Frequency Calibration ? Supports the clock drop interrupt funct

1 IntroductionThe time display function of the desktop Windows system is well known and implemented by the BIOS clock module. You can click the time in the lower-right corner of the taskbar of the desktop system to modify the current time and time zone, and synchronize time with the Internet.Currently, many popular embedded systems such as mobile phones, PDAs, and HMI (Human-Machine Interface Devices) have been transplanted to Microsoft's WindowsCE operating system. Although the wince system als

Instructor song,Hua Qing vision embedded college lecturer. 1.1 Introduction to rtc In an embedded system, RTC is usually used to provide reliable system time, including hour, minute, second, and year, month, and day, it is also required that the system work properly when it is shut down (usually powered by a backup battery ). Its Peripheral does not require too much auxiliary electrical channels. Typically,

For the MCU to arm of the students, the RTC may be less contact. Referring to the real-time clock, more often think of is DS1302. Of course, in the STM32, a CPU is enough, do not need to DS1302.In fact, RTC is just a timer, all the information is lost after power-down, so we need to find a place to store this information, so we find the backup register. Because it can still be powered by a button battery af

First, the RTC device is an on-chip device that uses platform_device to represent the device (that is, the RTC object of platform_device) the device has been registered into the system during device initialization (refer to the driver process of the device on SOC 2410 (RTC, watchdog, etc )), therefore, after the RTC dr

RTC driver in Linux- First, we will briefly introduce the similarities and differences between date and hwclock. Similarities: all represent time. Differences: Date indicates the system time. If it is not set when the system is started, the system will start from January 1, 1970. Hwclock indicates the time of the hardware, such as the time in the clock chip or the RTC of the main chip. Date is not introduc
