Hi.

I have a 1ms timed event that is supposed to poll a GPIO input every time it runs.

However, after boot up the timed event only runs once.

If I change the time period to 5 ms, the timed event seems to run the function quite regularly.

/******************************************************

*                    Constants

******************************************************/

#define SAMPLING_PERIOD (1 * MILLISECONDS)

#define BUTTON (WICED_GPIO_26) //Pin 30

#define RELAY_CTRL_OUTPUT (WICED_GPIO_23)

#define BUTTON_STATE_PERSISTENCE_WAIT_TIME (100)

/******************************************************

*               Static Function Declarations

******************************************************/

static wiced_result_t sampling_thread(void* arg);

/******************************************************

*               Variable Definitions

******************************************************/

static wiced_timed_event_t button_sampling_timed_event;

/* relay */

static wiced_bool_t g_relay_state = WICED_FALSE;

void application_start( )

{

    /* Initialise the WICED device */

    wiced_init();

    /* initialize the button input */

    /* button input */

    if( wiced_gpio_init( BUTTON, INPUT_HIGH_IMPEDANCE ) == WICED_SUCCESS ) {

        printf("Success: Button is set as GPIO i/p with high impedance\n");

    } else {

        printf("Failure: Button is set as GPIO i/p with high impedance\n");

    }

    /* initialize the relay to open */

    g_relay_state = WICED_FALSE;

    wiced_gpio_output_low(RELAY_CTRL_OUTPUT);

   /* Setup a timed event that will toggle RGB leds */

    wiced_rtos_register_timed_event( &button_sampling_timed_event, WICED_HARDWARE_IO_WORKER_THREAD, sampling_thread, SAMPLING_PERIOD, 0 );

}

static wiced_result_t sampling_thread(void* arg)

{

    UNUSED_PARAMETER( arg );

    current_button_state = wiced_gpio_input_get( BUTTON ) ? WICED_TRUE : WICED_FALSE;

    printf("current_button_state = %u\n", current_button_state);

  

   return WICED_SUCCESS;

}

This is on Inventek's ISM43341_M4G_L44 platform.

Adding dickb​ and als@inventeksys.com​ from Inventek. I'm not sure if they've tested their module yet with SDK 3.7.0

I can test this on the reference 43341 platform. Just wanted to know, if 1ms hardware IO priority timed event works in general with 3.7.0? I dont see any reference to any codebase in 3.7.0 SDK with such a timed event with 1ms periodicity?

Rather than poll, could you set up an interrupt on your GPIO instead?

Andrew,

Hi.

Thanks. I have thought about using this. However, as of now, 1 ms timed event is broken on WICED-3.7.0 and ISM43341 platform. It works well with the same hardware on WICED-3.5.1.

I am curious why that would be the case? I mean ThreadX version hasnt changed yet, it is still v5.6 unless some patches were applied in WICED-3.7.0 SDK?

Regards,

Manish

No.

This is a regression.

The correct thing to do is find the bad commit and either revert it or fix it.

Thanks. I completely agree, the context in which the 1ms timer is used is irrelevant ... It could have been used to consume bytes coming from the RX UART buffer on a 1ms basis.

This is clearly a regression.
