AWR1843BOOST: Data sent from AWR1843 to PC

Hiroyuki Kanematu
Expert 2975 points
Part Number: AWR1843BOOST
Other Parts Discussed in Thread: AWR1843,

The data measured by AWR1843 is Tag1, Len1, PayLoad1...TagN, LenN, PayLoadN as shown in the figure (N is each frame number), but the cycle of sending data to the PC is switched for each Tag Is this recognition correct?

See diagram below

Also, is it correct to assume that the recommended speed for sending each Tag is 921600 bps?

    Hi Hiroyuki-san,

    N is the number of Tags available throughout a given UART packet. Each UART output packet is updated and sent out every frame, not every tag (if what you mean by cycle is call to the UART output transmit function). The baud rate for any data going out through the UART data port is 921600 by default in the OOB demo.

    Let me know if you have further questions. If not, kindly request you to mark the thread as resolved.

    Regards,

    Kaushik

    PayLoadN of AWR1843BOOST (the Nth is a packet)

    When you say Frame, do you mean Tag, Len, PayLoad?

    Also, is it correct to assume that the Frame is the same as the data of one chirp frame?

    Also, regarding the baud rate, if the amount of data is small, should I lower it further?

    Hi Hiroyuki-san,

    By frame I am referring to a set of chirps fired and processed by the radar within a pre-set period of time (configured with frameCfg). Each frame's output consists of N sections in the UART output structure depending on the GUI monitors enabled.

    You do not necessarily have to reduce the baud rate if your data size is smaller.
