auto-timer
There are many types of automatic timers. The following are some common automatic timers:
- Hongrun timer/timer: Fully automatic chip packaging technology, strong anti-interference ability. 6-digit LED digital display with a wide display range. It has a variety of output functions, such as timing alarm control, timing alarm control, 485/232 communication, 200mS pulse width output, etc. The timing function can be used to start, stop, reset functions, and an external button can be selected. It is suitable for various occasions.
- [Children's timer: It has a cartoon appearance and does not require a battery. It is a mechanical model.] When using it, turn it to start the timer. Children can operate it themselves. There was a small stand on the back that could be placed on the table. It could also be magically attached to the refrigerator. When the time was up, it would automatically ring, helping to change the child's habit of procrastinating.
- STM32 Advanced Timers (TIM1 and TIM8): Part of the 32-bit microcontrollers based on the Arm Cortex-M core. It has 16-bit up, down, up/down (center-aligned) counting modes, an auto-loading counter, a 16-bit programmed prescaler, and the frequency division factor of the counter clock frequency is between 1 - 65536. Four independent channels can be used for input capture, output comparison, pulse width generation, single-pulse mode output, and other functions. There are also functions such as interrupting/uma when various events occur.
- Fully automatic electronic timer: It is one of the track timing methods. It is connected to the starting gun or other approved starting devices. The delay between the instant the gun flashes and the automatic start of the timer is less than 1/1000 of a second. A camera with a vertical gap was installed on the extension line of the finish line and recorded on a continuous running film. The film was marked with a 1/100 second time scale. The time and ranking of the athletes were determined from the film, and the results were the official results. If the timing device fails, the time will be calculated by the manual timing method of the substitute timekeeper. The results of some or all track events held outside the track and field field will be rounded up and converted into whole seconds.
- The iPhone's Automatic Inactivity Starter: If the iPhone is not used for a period of time (such as 3 hours), it will automatically restart based on this timer. This feature would cause an obstacle when Fabola (law enforcement officer) cracked the seized iPhone to obtain evidence, because the phone's automatic restart would force the cracking operation to be terminated.
