Research and implementation of physical layer protocol basing on the single-chip ZigBee platform of MC13213

In this paper we build a single-chip ZigBee hardware platform using Freescale MC13213, describe the basic content of physical layer protocol. By analyzing the programming structure of SPI services protocols and the Modem working mode in physical layer, we realize the designing of the underlying hardware drivers and the transmitting / receiving programs for the physical layer data packet with the component mode. Basing on this component mode we also do detailed test for the physical layer protocol to verify the reliability and stability of the physical layer functions. The results show that the single-chip ZigBee physical layer protocol is reliable and stable, and it can be applied in the actual projects easily.
