Abstract
In view of present using more and more serial communication and even not enough for embedded processor connected peripherals, this paper proposes multiple serial port communication design and implementation based on BF561 platform. With dual-core processor ADSP-BF561 as control core and uClinux as system software platform, using asynchronous serial communication chip TL16C554 by TI Co., Ltd, adopting the way of sharing interrupt to design and realize the multiple serial communication, saving valuable interrupt resources. This scheme successfully apply to the filed of wireless sensor networks for practical project.
