| titleOfInvention | Independent keyboard state recognition and coding circuit |
| abstract | A kind of independent keyboard state recognition and coding circuit are made of independent keyboard, the first buffer register, the second buffer register, encoder.The circuit is scanned via clock pulses, the positioning of state operation will be maintained to single key stroke, combination key operation, keyboard, it is converted into the effective status code of same binary length and disarmed state code, after encoded device coding, export effective key number corresponding with each effective status code and either export invalid key number corresponding with all disarmed state codes；Different single key stroke, combination key operation, keyboard maintain state operation to be only embodied in not being same as above for conditional code；Button operation function is either adjusted if necessary to increase and decrease button operation function, keyboard scanning circuit structure need not be changed, only need to encoder be changed according to the correspondence between the conditional code after increase and decrease and key number.The invention circuit does not have to write and operation program, reliable operation. |
