How does the elevator call work?
Short-circuit SET and press the up and down buttons to set the floor. WDT is the abbreviation of English Watchdog Timer. Watchdog Timer Chinese name is watchdog. It is a timer circuit. It generally has an input called the dog feed, and an output to the RST terminal of the MCU. When the MCU is working normally, it outputs a signal to the dog feed terminal every once in a while to clear the WDT. If it exceeds the specified limit If time does not feed the dog, (generally when the program runs away), if the WDT timer exceeds, a reset signal will be given to the MCU to reset the MCU and prevent the MCU from crashing. The function of the watchdog is to prevent the program from endless loops, or in other words Program runs away.
