Introduction: The watchdog in hardware is not the gatekeeper's idea, but a very fierce dog! If you don't feed it on time, it's going to restart the system! This is the function we want ~1. Watchdog overviewThe watchdog timer (Wdt,watch dog timer) is an integral part of the microcontroller, it is actually a counter, gen

background Application 100% Loss completely failed to start and crashed. Completely cut off the network connection normal boot, debugging mode state of waiting time is very long, but can be started, and with the UI micro-card. A strong feeling that this is thread blocking. Some time ago by the Core Data concurrency toss, see thread problem is slightly flustered. reason First look at the crash log, as a guess, is really stuck in the main thread; unexpectedly, countless flash-back left only a cra

To prevent an application from consuming too much system resources, the Apple Engineer Gate that developed iOS designed a "watchdog" mechanism. In different scenarios, the watchdog monitors the performance of the application. If the runtime is exceeded by the scenario, the watchdog will force the end of the application process. In Crashlog, developers will see er

Watchdog should be familiar with those who have experience in MCU learning. However, if watchdog is used correctly, I am afraid you will not have a deep understanding of the actual product development. The ressa rl78 series microcontroller has its own watchdog. When the watchdogtimer timer is enabled, 75% of the

MSP430 microcontroller adconverter 20:14:05 | classification: MSP430 microcontroller | report | font size subscription I. Brief Introduction: The adc12 module consists of the following parts: the input 16 analog switches (eight external channels, four internal channels), the ADC internal voltage reference source, the adc12 kernel, and the ADC clock source, collection and holding/trigger source, ADC data out

watchdog technology has long been more and more into the microcontroller system. It has become a standard component in the embedded system so far. at the same time, the research on the application of watchdog technology has been greatly developed. Of course, in the most common front and rear systems, usually placed in the foreground of the main loop to feed the

1. What is watchdog? Watchdog, the Chinese name is "Watchdog" and its full name is watchdog timer. We can literally know that it is actually a timer. However, it is different from the Timer we normally use. A common timer generally serves as a timer, and a timer timeout (timer out) causes an interruption, for example,

The following code is a single-chip microcomputer program, 51 microcontroller, compiler for ht-ide3000,Simply put,Can only be stated in the header file,When the variable is declared in the header file, add the extern keyword to tell the compiler that the variable is defined in other files,Enum is not a variable, it is a data type we define ourselves, like int char, but we define it ourselves, so we don't have to add it.1 externU16 G_u16timebasecount;2
