RS-485 Automatic Direction Control Reference Design
Texas Instruments
The TIDA-01090 reference design enables half-duplex communication over an RS-485 bus without requiring additional driver-enable/receiver-enable controls. The design allows for the transceiver used on each node to go into transmit mode automatically when data is being transmitted from a local Microcontroller (MCU) or Universal Asynchronous Receiver/Transmitter (UART) and then transition back into receive mode once the data frame is complete.
Features
- Automatically enables an RS-485 driver when data is output from an MCU or UARTTransitions RS-485 transceiver into receive mode when data is not being transmittedWorks with any RS-485 transceiverLow-cost due to minimal number of componentsAdjustable data frame length via passive component selection
