Title:
KEY CONTROL APPARATUS AND KEY CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2022/178835
Kind Code:
A1
Abstract:
Disclosed are a key control apparatus and a key control method. The key control apparatus comprises: an encoder circuit, wherein the encoder circuit comprises a first output end and a second output end, and the encoder circuit is configured to enable, under the trigger of a rotation operation, the first output end and the second output end thereof to respectively output a first voltage signal and a second voltage signal; a first interface expansion circuit, configured to receive the first voltage signal and the second voltage signal, and generate an interrupt signal and voltage state transition data in response to the first voltage signal or the second voltage signal output by the encoder circuit; and a main control circuit, configured to determine a rotation direction of the rotation operation according to the interrupt signal and the voltage state transition data.
