The Development Of Bluetooth Wireless Keyboard And Mouse

As a kind of advanced wireless communication technology, Bluetooth has very good prospects to the wireless keyboard mouse. The paper has described the intact solution of the bluetooth keyboard mouse products at low cost.The ASIC chip embedded with bluetooth is usually employed as keyboard mouse equipment controller at present, so that is complicated and expensive to realize. Noteworthily a new style of design is developed in the article: a 51 MCU is employed as keyboard mouse equipment controller while controlling bluetooth module as host, which give full play to 51 MCU and make the product at low cost, the design has sure practicability and innovative; The software of PC end is designed as operating in the backstage, which receives data from USB interface to simulate the function of the keyboard and mouse. The design is easy,the thought is ingenious.Three kinds of solutions of the bluetooth keyboard mouse system were put forward in the paper.among them the solution selected in the subject was especially introduced,which includes Overall conceptual design , development environment introduce, system circuit design, keyboard and mouse controller software design, PC end software design and system debug etc.The subject is a successful attempt to apply bluetooth wireless communication technology to computer peripheral. The system dvelopment was completely realized, and which make the preparation of theory and practice for the next stage ripe product.
