| titleOfInvention | A kind of keyboard state change pulse generation method |
| abstract | The invention discloses a method for generating a keyboard state change pulse, which judges whether the M-position key number output by the keyboard state identification and coding circuit changes, and outputs a keyboard state change pulse when the M-position key number changes. Determining whether the M-bit key number has changed is realized by an M-bit delay buffer and M XOR gates. The M-bit delay buffer delays the signal of the M-bit key number respectively, and the M XOR gates are used to determine whether the M-bit key number is not. The input of the M XOR gates are the input and output signals of the M-bit delay buffer respectively; the keyboard state change pulse is output by the OR gate; the outputs of the M XOR gates are respectively connected to the input terminals of the OR gate. If the method needs to increase or decrease the key operation function or adjust the key operation function, it does not need to modify the circuit structure, but only needs to change the keyboard state recognition and the encoding content of the encoder in the encoding circuit, without writing and running a program, and works reliably. |
