Abstract:
1. A system for facilitating communication between an upstream device and a downstream device having a plurality of channels, the system comprising: an upstream universal asynchronous receiver transmitter (UART) coupled to receive communications from and transmit communications to the upstream device, and to transmit communications directly to and receive communications directly from a bus; a number N of downstream UARTs, each being coupled to one of the plurality of channels of the downstream device, for receiving communications from and transmitting communications to the downstream device, and being coupled to transmit communications directly to and receive communications directly from the bus; a processor for coordinating the transfer of communications between the upstream UART and the downstream UARTs; and a register portion, coupled to the bus, for communicating an LED drive signal; wherein communications between the upstream device and the upstream UART occur at a first rate and communications between the downstream UARTs and the downstream device occur at a second rate, the first rate being faster than the second rate.
