[0019] Please refer to figure 1 , figure 1 It is a block diagram of an electronic device according to the first embodiment. The electronic device 1 is, for example, a multimedia player, a tablet computer, a mobile communication device or other portable electronic devices, and the electronic device 1 includes a capacitive sensor 11 , a central processing unit 12 , a reminder device 13 and a memory 14 . The capacitive sensor 11 is, for example, a proximity sensor (Proximity Sensor / P Sensor), and the capacitive sensor 11 generates a capacitance change when a user approaches to output a wake-up signal W correspondingly. The capacitive sensor 11 includes a sensing output pin 111 , and the CPU 12 includes a wake-up pin 121 . The wake-up pin 121 can also be called a wake-up event input, and the wake-up pin 121 is coupled to the sensing output pin 111 . The CPU 12 is coupled to the reminder device 13 and the memory 14 . The memory 14 stores the events to be processed, and the remi...

[0022] Please refer to figure 1 and image 3 , image 3 It is a block diagram of an electronic device according to the second embodiment. The main difference between the electronic device 2 and the electronic device 1 is that the electronic device 2 further includes a pin extension assembly 15 . The pin expansion component 15 is, for example, a general purpose input / output (General Purpose I / O, GPIO) expander, a keyboard controller or a microprocessor, and the pin expansion component 15 includes a plurality of expansion input pins 151 and expansion output pins 152. One of the expansion input pins 151 is electrically connected to the sensing output pin 111 to receive the wake-up signal W, while the other expansion input pins 151 can be used by other components that need to output the wake-up signal to the central processing unit 12, such as Wi- Fi chip or power button. The expansion output pin 152 is electrically connected to the wake-up pin 121 to output the wake-up signa...

Abstract

An electronic apparatus is disclosed. The electronic apparatus comprises a capacitive sensor and a central processing unit (CPU). The capacitive sensor comprises a sensor output pin, and the CPU comprises a wake-up pin. The wake-up pin is coupled to the sensor output pin.

Description

technical field [0001] The present invention relates to an electronic device, and more particularly to an electronic device using a capacitive sensor. Background technique [0002] In a modern information society with highly developed technology, electronic devices are widely used in daily life. People can use electronic devices to exchange information, share experiences or communicate opinions anytime and anywhere. For example, the user can answer incoming calls, check messages or check letters through the electronic device. If the user does not answer the incoming call, check the message or check the letter in real time, the subsequent electronic device will enter the standby mode. [0003] Currently, when the electronic device is in the standby mode, the user needs to open the screen of the electronic device to check whether there is an event to be processed. Pending events are, for example, missed calls, new messages or new letters. Alternatively, the electronic devi...
