Key detection circuit and detection method

The invention relates to the technical field of circuit detection, in particular to a key detection circuit and a key detection method. The key detection circuit comprises a detection circuit which is arranged in a detection chip and is used for detecting a key input state received from a GPIO (General Purpose Input/Output) interface of the detection chip; the input circuit is electrically connected with the GPIO interface of the chip and is used for providing key operation for a user; the method has the advantages that GPIO (General Purpose Input/Output) resources are saved under the condition that the number of the keys is less than 15, the conflict of combined keys is solved, and the use cost is lower. 本发明涉及电路检测技术领域，具体涉及一种按键检测电路及检测方法；一种按键检测电路，包括，检测电路，设置于检测芯片的内部，用于检测自所述检测芯片的GPIO接口接收到的按键输入状态；输入电路，与所述芯片的GPIO接口电性连接，用于提供给用户进行按键操作；优点：在按键个数少于15个的情况下节省GPIO资源，解决了组合按键的冲突，且使用成本更低。
