CCS / AWR1843：How do I use the GPIO Demo in the SDK?

user6248944

Part Number: AWR1843


Tool/software: Code Composer Studio

Now, I want to use the GPIO in C:\ti\mmwave_sdk_03_03_00_03\packages\ti\drivers\gpio. I want to know how do I use this code in CCS. And I am a novice, I want to know what it takes to build a new project in CCS, what files to configure, and so on. Are there any valuable references?

    Hi,

    Please refer mmwave sdk user guide which explains to use CCS to load the application image.

    Hello!

    For blink onboard led I used example from Jitendra Gupta, but with one addition.

    To initialize GPIO_1 and GPIO_2 use this code:

        /* Initialize the GPIO */
    GPIO_init ();
    /**********************************************************************
     * Setup the PINMUX:
     * - GPIO Input : Configure pin J13 as GPIO_1 input
     * - GPIO Output: Configure pin K13 as GPIO_2 output
     **********************************************************************/
    Pinmux_Set_OverrideCtrl(SOC_XWR18XX_PINJ13_PADAC, PINMUX_OUTEN_RETAIN_HW_CTRL, PINMUX_INPEN_RETAIN_HW_CTRL);
    Pinmux_Set_FuncSel(SOC_XWR18XX_PINJ13_PADAC, SOC_XWR18XX_PINJ13_PADAC_GPIO_1);

    Pinmux_Set_OverrideCtrl(SOC_XWR18XX_PINK13_PADAZ, PINMUX_OUTEN_RETAIN_HW_CTRL, PINMUX_INPEN_RETAIN_HW_CTRL);
    Pinmux_Set_FuncSel(SOC_XWR18XX_PINK13_PADAZ, SOC_XWR18XX_PINK13_PADAZ_GPIO_2);

    /**********************************************************************
     * Setup the DS3 LED on the EVM connected to GPIO_2
     **********************************************************************/
    GPIO_setConfig (SOC_XWR18XX_GPIO_2, GPIO_CFG_OUTPUT); // It is addition, without it don't work.

    before you need add a lot of  headers in project.

    In clock task use this code:

     GPIO_toggle(SOC_XWR18XX_GPIO_2);
