watchdog generator

In Feature phone's production release version, (1) the system fails to capture memory dump or (2) watchdog timeout when the JTAG is used to analyze the problem. You can disable watchdog to debug the problem, the method for disabling is as follows: The method of disabling watchdog in 11A before is to change the parameter in the WDT_Enable () function to kal_FALSE

Generator and iterator in python, python generator Generator I personally think that iterator and yield implement the same functions, but iterator must be implemented in the class, and yield is implemented in the real function, both of which will save the status. The generator is also implemented by the iterator. #! /U

Bug in STM32F4 Series MCU, window watchdog WWDG. 1. If it is possible to pre-feed the dog interrupt, then the following two points must be met (1) Before turning on the WWDG interrupt, the EWI flag bit in the SR register must be zeroed out, otherwise the watchdog will constantly reset (2) Add a small delay to the WWDG_IRQ, otherwise the watchdog will be const

A Overview Some important program must keep it running, and always care about its state------------can't let it deadlock. Of course, if a main program has a deadlock, it must be a design or programming error. The first thing we do is to get this bug out. But if the time is tight, this bug and "erratic", then, we still write a software "watchdog", temporarily should be urgent. Description of "Watchdog" req

The watchdog of recent projects has undergone three version numbers.First version number:With PS-EF, if the program hangs, it starts.Second version number:The program will not listen to the 7901port when it executes, so it is not easy to infer whether the machine is dead, but to infer if the port is listeningThird version number:When the 7901port is no longer listening, the original killall will be restarted first. Every time you output to a file, add

The watchdog of the recent project has undergone three versions.First version:With PS-EF, if the program hangs, it starts.A second version:program because the runtime will not listen to the 7901 port, so it is not easy to determine whether the machine is hanging, but to determine if this port is listeningA third version:When the 7901 port is no longer listening, the original killall in the start, each output to the content of the file to add the date,

The function of the data link layer is to form meaningful messages from the physical layer and provide transmission control procedures such as error control. The function of the data link layer is usually executed in the hardware of the CAN controller;Frame concept: Data frame: the frame used by the sending unit t

Advanced Usage Analysis of the iterator and generator in Python, python Generator Iterator An iterator is an object attached to the iteration protocol. It basically means that it has a next method. When called, it returns the next item in the sequence. When no project can be returned, A (raise) StopIteration exception is thrown. The iteration object allows a loop. It retains the state (location) of a single

tool, even if it provides an infinite number of primes is completely feasible, because it provides only one prime each time, there is no memory exhaustion problem. So, does this tool exist? Of course there is, and the name is called Generator (generator).2, Generator (Generator) Principle Introduction: There is a keyw

With a deep understanding of the Python Generator (Generator), we can simply create a list using the list generation method, but the list capacity is limited due to memory restrictions. In addition, creating a list containing 1 million elements not only occupies a large storage space, but if we only need to access the first few elements, the space occupied by the vast majority of elements is wasted. Theref

This article mainly introduces the details of the Python Generator (Generator). This article describes what generators are, simple generators, generators with yield statements, and enhanced generators, for more information, see generate a list. However, due to memory restrictions, the list capacity must be limited. In addition, creating a list containing 1 million elements not only occupies a large storage
