IWR6843AOP: When I use IWR6843AOP's Uart to read data, data leakage is easy to occur. Is there an interrupt function on the Uart of 6843?

Part Number: IWR6843AOP

Hello

1. When I use IWR6843AOP's Uart to read data, data leakage is easy to occur. Is there an interrupt function on the Uart of 6843?

2. As shown in the figure below, this is a cyclic read running in the Task, which is easily interrupted by other tasks, resulting in incorrect data read and inability to read AT instructions completely.

3. Is there a better way to achieve it?

    Hello,

    Please check <SDK_INSTALL_DIR>\packages\ti\drivers\uart\UART.h. There are also examples of using the UART driver in the SDK.

    I would recommend using UART_writePolling and UART_readPolling as they should wait until all bytes are read/written before exiting.

    Regards,

    Hello,

    Can you read the serial port data without using the while loop and directly use the interrupt mode to read it?

    Hi,

    While this is technically possible, we don't provide any examples for this in the SDK, and I cannot find any examples that we have written. It would take some more investigating into the SDK to set up the UART instance correctly.

    I would recommend continuing to use the polling method.

    Regards,
