    UART RTS-CTS with circular software buffer for CY8CKIT-145-40XX




      This is a sample project that prepares 300 bytes of UART software buffer and controls RTS-CTS.


      If you press SW2, the data sent from TX of UART is looped back by RX, and the data is sent to the terminal software of PC by Software Transmit UART.

      The configuration of RTS-CTS is as follows.

      The configuration of both circular software buffer TX and RX are as follows.

      You must wire RTS to CTS and TX to RX with external wiring.

      Make sure to pull up via the resistors on CTS and RX.

      If you press SW2, you will receive a message.

      Best regards,
