Using a UART to Implement a 1-Wire Bus Master


关键词: UART, DS9097E, 1-Wire, iButton, bus master, 1-Wire signals, microprocessor, 1wire


Abstract: This application note explains how to use a microprocessor's UART to implement a 1-Wire® bus master. It includes an explanation of the required electrical interface, UART configuration, and timing relationship between UART and 1-Wire signals. The flexibility offered in setting up UART byte timing allows straightforward implementation of 1-Wire time slots as well as the reset and presence detect pulses. With the inclusion of deep transmit and receive FIFOs, several byte values can be transferred on the 1-Wire bus with just a few clock cycles per bit required from the main processor.
