Problems solved by technology

For example, mobile devices, MP3, MP4 and other devices are generally realized through the reset hole, but this method requires the user to use a small tool to penetrate into the reset hole and touch to complete the reset. If there is no suitable external tool, the reset cannot be triggered, which is very difficult to use. inconvenient

Abstract

The invention provides a reset circuit which comprises a charging circuit, a driving circuit and an executing circuit. The charging circuit is used for generating second voltage signals after first voltage signals provided by a control port are received; the driving circuit is used for amplifying the second voltage signals after values of the detected second voltage signals reach preset values, and outputting the amplified second voltage signals to the executing circuit; the executing circuit is used for generating reset signals after the amplified second voltage signals are received, and transmitting the reset signals to a reset port. The invention further provides electronic equipment. The electronic equipment comprises the reset circuit, a key and a microcontroller. The first voltage signals are provided by the control port when the key is pushed; reset operation is carried out on the microcontroller by the reset port when the reset signals are received. The reset circuit and the electronic equipment in an embodiment of the invention have the advantages that a key does not need to be individually occupied to specially carry out reset operation, the existing key can be pushed, accordingly, reset functions of the reset circuit and the electronic equipment can be implemented without external tools, and mistaken contact can be effectively prevented.

Description

technical field [0001] The invention relates to electronic equipment, in particular to a reset circuit in the electronic equipment. Background technique [0002] Electronic equipment generally has a reset function. When the electronic equipment crashes due to improper operation or internal problems in the product, it is necessary to activate this reset function, that is, it can restore the electronic equipment to its original state without power interruption. In the prior art, the reset in the electronic equipment mostly adopts the implementation manner of a separate reset key or a power-off toggle switch. For example, mobile devices, MP3, MP4 and other devices are generally realized through the reset hole, but this method requires the user to use a small tool to penetrate into the reset hole and touch to complete the reset. If there is no suitable external tool, the reset cannot be triggered, which is very difficult to use. inconvenient. In some tablet computers and other...
