The invention discloses a method and a device for realizing one-button switch machine. The method for realizing one-button power-on includes: turning on a switch, connecting an external power source, generating an enabling effective level of a power converter according to the external power source, so that the power converter converts the level of the external power source to the first A level; the first level is a level that enables the processor to work normally; the processor is started according to the first level; the power converter is generated according to the first level. an active level, keeping the enabling end of the power converter at the enabling active level; turning off the switch. Through the embodiment of the present invention, one-button switch is adopted for the terminal, the circuit is simple and easy to use, the function is stable and reliable, the efficiency of terminal switch is improved, and it is suitable for general promotion.
Description
technical field [0001] Embodiments of the present invention relate to the field of electronic technology, and in particular to a method and device for realizing one-button power on and off. Background technique [0002] One-button switch, that is, the system is turned on and off with the same action. The main purpose of booting is to start and maintain the power supply to make the system work normally; the main purpose of shutting down is to detect the shutdown signal, save the necessary system information, and turn off the power supply. [0003] The one-button power on / off mode has gradually become one of the main ways to power on and off terminal electronic products, such as mobile phones, due to its safe and reliable information storage and simple operation. [0004] The existing one-button switch machine adopts two kinds of realization ways to realize. One is to use a self-holding button switch to change the switch state through a mechanical button action to control th...
