CC1352R: Enable Hardware Flow Control in Coprocessor example (CTS and RTS)

Part Number: CC1352R
Other Parts Discussed in Thread: SYSCONFIG

Hi there,

I want to enable hardware flow control in the Coprocessor example (SDK 6.40.00.13). This Interface Guide mentions that it should already be enabled in the default UART configuration. 

 

However, I'm unable to check the Flow Control box in sysconfig.




If I choose "None" for the Hardware of UART2, it lets me enable Flow Control, but then I'm not sure how to select the GPIOs that will be used.


What would be the recommended approach for enabling hardware control in the Coprocessor example? I need this implementation in order to evaluate a protocol converter that might be launched in our product soon. 

Thanks for helping!

    Hi Arthur,

    Keep in mind that the default UART configuration communicates with the PC through the XDS110 uart.

    It might be wise to use other pins for that. In order to do so:

    1. Under TI DRIVERS -> Display, set Use Hardware to "None" (as it seems like you already did)
    2. Now, go to TI DRIVERS -> UART2, you should see that the UART is now called CONFIG_UART2_0, or CONFIG_DISPLAY. Rename it to CONFIG_DISPLAY_UART.
    3. Enable Flow Control.
    4. Now you can check what pins are assigned, and configure them on the same window, under "PinMux"

    I have attached a SysConfig file, so that you can compare afterwards.

    coprocessor.syscfg

    Regards,
