| titleOfInvention | Matrix keyboard scanner uni coding circuit |
| abstract | A kind of matrix keyboard scanner uni coding circuit is made of matrix keyboard, the first buffer register, the second buffer register, state Code memory, encoder, data combination unit.The matrix keyboard scanner uni coding circuit is via clock pulses, the control of scanning pulse, sampling pulse, 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 invalid state code, after encoder encodes, export effective key number corresponding with each effective status code and either export invalid key number corresponding with all invalid 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, 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. |
