摘要

To establish a reliable UART-based bus network, some connection proposals are presented and analyzed. Three alternatives of the bus topology are given to establish the communication. Communication performance is individually researched from three aspects. UART's interface and wire properties determine the highest baudrate. The transmission-related analysis shows that the baudrate-recalibrated time is determined by two aspects that are the inter-slot condition and the intra-slot condition. The protocol-related analysis shows that the communication effect is scaled by four aspects, which are start-stop protocol efficiency, wire's busy/idle, data understanding rate and temporal characteristics.
