| titleOfInvention | Independent keyboard scanning circuit and scanning encoding 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 scanning encoding method of the scanning circuit is, scanning circuit is via the control for meeting scanning pulse, shift pulse that specific time sequence requires, scan the state that single key stroke, combination key operation and independent keyboard maintain, and the effective status code of same binary length and invalid state code are converted into, effective key number corresponding with each effective status code is exported after coding circuit encodes and either exports invalid key number corresponding with all invalid state codes；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, does not need to modification keyboard scanning circuit structure, 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 run program, reliable operation. |
