| Abstract: | Owing to the high software-hardware cost and slow working speed of the existing keyboard circuit,the author studies a new-style static code keyboard circuit. This article analyzes its design methods and working theories, and contrastively demonstrates its feasibility and practicability, and simply narrates the concrete use of the interface circuit - 8279. All of these further clarify that the code keyboard is more excellent than all sorts of existing mechanical keyboards. |
