Hi there,
I am using the uart example with SD130 and added neopixel code from GIT to drive the WS2812B LEDs using bit banging. I want to update the LED every ms. The bitbanging sequence used in neopixel_show(&m_strip); must not be interrupted. To achieve this I am using this code
ble_radio_notification_init(NRF_RADIO_PRIORITY_NORMAL ,
NRF_RADIO_NOTIFICATION_DISTANCE_800US,
led_radio_callback_handler);
void led_radio_callback_handler(bool radio_active)
{
if (radio_active == false)
{
softdevice_active = false;
} else {
softdevice_active = true;
}
}
static void ms_timeout_handler(void * p_context) // 1ms Timer
{
// uint32_t err_code;
UNUSED_PARAMETER(p_context);
// nrf_drv_gpiote_out_toggle(BSP_LED_2);
// ms_timer_ticks++;
if (softdevice_active == false)
{
// CRITICAL_REGION_ENTER();
// sd_nvic_critical_region_enter(&p_is_nested_critical_region);
__disable_irq();
neopixel_show(&m_strip);
__enable_irq();
// CRITICAL_REGION_EXIT();
// sd_nvic_critical_region_exit(p_is_nested_critical_region);
} else {
nrf_drv_gpiote_out_toggle(BSP_LED_2);
}
}
The above code works but I read in a different thread that it is not recommened to use __disable_irq() together with a SD. The the other two methods that are outcommented do not work proberly. I still get interrupts just before the notfication:
The question is:
Can I use __disable_irq() in this special case or what would be your recommendation?
Thanks
Peter
