Keyboard device and electronic device connected with keyboard device

Abstract

A keyboard device includes a key array, a power terminal, a communication terminal, a ground terminal, memory storing one or more computer programs, and one or more processors communicatively coupled to the power terminal, the communication terminal, the ground terminal, and the memory, wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the keyboard device to detect electrical connection to an external electronic device through the power terminal, the communication terminal, and the ground terminal, when electrically connected to the external electronic device, receive a key input through the key array, in response to the key input, generate first encoded data having a first error correction rate and second encoded data having a second error correction rate greater than the first error correction rate, combine the first encoded data and the second encoded data to generate input data, and transmit the input data to the external electronic device through the communication terminal.
