Question:
UART Flow Control Between Two Boards
Answer:
This example demonstrates UART communication with hardware flow control between two boards:
-
ADSP-SC584 – Transmitter (TX)
-
ADSP-SC589 – Receiver (RX)
The ADSP-SC-584 transmits UART data, and the ADSP-SC-589 receives the data using UART hardware flow control (RTS/CTS). This example has been tested with CCES 2.12.0 on the ADSP-SC584 Evaluation Board and ADSP-SC589 Evaluation Board.
Hardware Setup
Connect the following UART signals between the two boards using an extender:
