CC2640R2F-Q1: CC2640x UART Typical Baud Rates and Errors,

Part Number: CC2640R2F-Q1

Hi,

Is there any equation to calculate CC2640xx UART receive error and transmit error?

Usually MCUs like MSP430 has details of "Commonly Used Baud Rates, Settings, and Errors"
in the user guide as shown below.
How do we calculate errors of UART communication in case of CC2640xx?

Best Regards
paddu

    Hello,

    We do not currently have a table like this published.
    You can find information about the UART peripheral in Chapter 19 of the TRM: www.ti.com/.../swcu117

    I have reached out to our hardware team to see if they have additional information.

    Hi Sean,

    Thank you for the information.

    Please let me know if you have any such table describing the
    Commonly Used Baud Rates and errors.

    Additionally we would like to know if there is any mechanism in the UART hardware
    to avoid like START bit error i.e. Synchronization error when the falling edge of the START bit is detected.
    especially when receiving long data(like 256 bytes) at a time.

    Hi paddu,

    The TRM and datasheet contains the information that we currently have available.
    I have notified the hardware team to comment on this thread if they have any additional information. Otherwise, this may be all that is available.

    Hi Sean,

    Thank you,

    Please let me know if there is any information about the Synchronization error
    and how it is handled in CC26xx UART for lengthy data.

    Best Regards
