LAUNCHXL-CC2640R2: Example codes, UARTECHO not working

Hello Arthur,

Thank you for the information.

Also, question on interrupt was about FIFO data to read.
I used to set a callback for each Byte arrived in the FIFO, then I have to read it.
How can I link Interrupt register to callback for each data read by UART ?
The example is about a callback triggered by a call to read method.

Hi Arthur,

Thanks. Yes, IFLS can be a solution. I found it in swcu117h.pdf. But I have not found sample to use it.

How can I access UART's registers? There is nothing about that in UART.h.

Hi Archie,

You don't need to access the registers directly. Indeed, from the documentation: https://dev.ti.com/tirex/explore/content/simplelink_cc2640r2_sdk_5_30_00_03/docs/tidrivers/doxygen/html/_u_a_r_t_c_c26_x_x_8h.html

You can see that we can configure those interrupt thresholds from the initialization structure of the driver:

const UARTCC26XX_HWAttrsV2 uartCC26xxHWAttrs[] = {
    {
        .baseAddr    = UART0_BASE,
        .powerMngrId = PERIPH_UART0,
        .intNum      = INT_UART0,
        .intPriority = ~0,
        .swiPriority = 0,
        .txPin       = Board_UART_TX,
        .rxPin       = Board_UART_RX,
        .ctsPin      = Board_UART_CTS,
        .rtsPin      = Board_UART_RTS
        .ringBufPtr  = uartCC26XXRingBuffer[0],
        .ringBufSize = sizeof(uartCC26XXRingBuffer[0]),
        .txIntFifoThr= UARTCC26XX_FIFO_THRESHOLD_1_8,
        .rxIntFifoThr= UARTCC26XX_FIFO_THRESHOLD_4_8
    }
};

Please note that they have to use the UARTCC26XX.h driver. They will find examples on how to use it the documentation link I sent.

Regards,

Arthur
