Design and Application of Serial Data System
Abstract In today's science and technology development and progress, the microcontroller growing role is not limited to control peripheral devices, the communication control system in use in today's increasingly valued by the people. In most of today's convergence program, covering the traditional serial devices inevitable, and one in particular, a serial communication when the remote transmission of data to avoid a series of problems due to multiple lines characteristic inconsistency arising happen, so daily life serial communications are widely used. Therefore, this article is to achieve is to simulate a simple serial data transmission, that is, computer terminal and MCU serial connection, so that the computer side data via serial communications delivered to the microcontroller, and a microcontroller to PC computer terminal data real-time display and update.
