| titleOfInvention | independent keyboard scanning circuit and method |
| abstract | A kind of independent keyboard scanning circuit is made of independent keyboard, the first shift register, the second shift register, state Code memory, encoder.The scan method of the scanning circuit is, via the control for the scanning impulse, shift pulse for meeting specific time sequence requirement, scan the state that single key stroke, combination key operation and independent keyboard maintain, and the effective status code of same binary length and disarmed state code are converted into, output effective key number corresponding with each effective status code either exports invalid key number corresponding with all disarmed state codes after encoded device coding；The state that different single key stroke, combination key operation and independent keyboards maintains only is 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. |
