ABSTRACT:
A peer-to-peer communication system includes multiple microcontrollers where each microcontroller has a microprocessor, memory, and an asynchronous receiver-transmitter connected by a parallel bus. A serial bus includes transmit, receive, and request lines. Each of the controllers is connected to the transmit and receive lines of the serial bus by way of its asynchronous receiver-transmitter. Each microcontroller is connected to the request line of the serial bus through an I/O port. A microcontroller detects an idle period on the serial bus and seizes control of the serial bus using that request line. The asynchronous receiver-transmitter is preferably a conventional universal asynchronous receiver-transmitter (UART). Thus, peer-to-peer communications are coordinated in a simplified fashion so that each device on the network can independently communicate with any other device on that network using standardized, industry accepted hardware and protocols.
