os_cputime_timer_init

void os_cputime_timer_init(struct hal_timer *timer, hal_timer_cb fp, void *arg)

Initializes a cputime timer, indicated by timer, with a pointer to a callback function to call when the timer expires. When an optional opaque argument is specified, it is passed to the timer callback function.

The callback function has the following prototype:

void hal_timer_cb(void *arg)

Arguments

Arguments	Description
timer	Pointer to the hal_timer to initialize. This value cannot be NULL.
fp	Pointer to the callback function to call when the timer expires. This value cannot be NULL.
arg	Optional opaque argument to pass to the hal timer callback function.

Returned values

N/A

Notes

Example

Example of ble_ll setting up a response timer:

ble_ll_wfr_timer_exp(void *arg)
{
    int rx_start;
    uint8_t lls;

         ...

    /* If we have started a reception, there is nothing to do here */
    if (!rx_start) {
        switch (lls) {
        case BLE_LL_STATE_ADV:
            ble_ll_adv_wfr_timer_exp();
            break;

         ...

        /* Do nothing here. Fall through intentional */
        case BLE_LL_STATE_INITIATING:
        default:
            break;
        }
    }
}

void ble_ll_init(void)
{
       ...

    os_cputime_timer_init(&g_ble_ll_data.ll_wfr_timer, ble_ll_wfr_timer_exp, NULL);

       ...
}
