Start stop button ?

[RixtronixLAB]

Dear Members,

How can I make a start/stop button with 1 button ?

Here's my handler :

void bsp_event_handler(bsp_event_t event)
{
    switch (event)
    {
        case BSP_EVENT_SLEEP:
            nrf_pwr_mgmt_shutdown(NRF_PWR_MGMT_SHUTDOWN_GOTO_SYSOFF);
            break;
				
				 case BSP_EVENT_KEY_0:
					 NRF_LOG_INFO("BSP_EVENT_KEY 0 PUSH ON\n");
            if (actual_state != BSP_INDICATE_FIRST)
                actual_state--;
						    //NRF_LOG_INFO("BSP_EVENT_KEY 0 PUSH ON\n"); //2Mar22 Rixtronix LAB
            else
                actual_state = BSP_INDICATE_LAST;
						    NRF_LOG_INFO("BSP_EVENT_KEY 0 PUSH OFF\n"); //2Mar22 Rixtronix LAB
            break;
            ............

Any clues ?

Kind regards,

Hi Karl,

from ble_peripheral directory examples above,

which example is using button with SYSTEM_OFF,

and which example is using "button long push" for event ?

Hi Karl,

I made ,

Callback :

case BSP_EVENT_KEY_2:
					 NRF_LOG_INFO("BSP_EVENT_KEY 2 PUSH ON\n");
				   //if(button2_state)
							//			{  
																				
												//ON_function();
											   err_code = app_timer_start(m_button_action, 
                                     APP_TIMER_TICKS(BUTTON_STATE_POLL_INTERVAL_MS),
                                     NULL);
												APP_ERROR_CHECK(err_code);
											 // NRF_LOG_INFO("BSP_EVENT_KEY 2 PUSH ON==> LONG PUSH >200ms\n");
											 //beep_v11();
											
												button2_state = STATE_OFF;
								//		}
									
            if (actual_state != BSP_INDICATE_FIRST)
                actual_state--;
            else
                actual_state = BSP_INDICATE_LAST;
                
                //timeout handler 
                
                
void button_push_timeout_handler(void * p_context)
{ 
     uint32_t err_code;
     static uint32_t cnt;

     if (BUTTON_3==0)
     {
         cnt++;
         if ( cnt >= LONG_PRESS(1000))
         {
             cnt = 0;
             NRF_LOG_INFO("Long Button press");
         }
         else
         {
              err_code = app_timer_start(m_button_action, 
                                         APP_TIMER_TICKS(BUTTON_STATE_POLL_INTERVAL_MS),
                                         NULL);
              APP_ERROR_CHECK(err_code);
         }
     }
     else
     {
          cnt = 0; // reset counter variable
          NRF_LOG_INFO("Short button press");
     }
}     

err_code = app_timer_create(&m_button_action, APP_TIMER_MODE_SINGLE_SHOT, button_push_timeout_handler);
      APP_ERROR_CHECK(err_code);
	      NRF_LOG_INFO("&m_button_action init Line2119...");
            break;

Timer init :

//long press button timer 16Mar22 Rixtronix LAB
APP_TIMER_DEF(m_button_action);
#define BUTTON_STATE_POLL_INTERVAL_MS  100UL
#define LONG_PRESS(MS)    (uint32_t)(MS)/BUTTON_STATE_POLL_INTERVAL_MS 

I got always in :

   NRF_LOG_INFO("Short button press");

although I push long enough...

What do we miss here ?

Hi Karl,

I pushed BSP_BUTTON_2, but on timeout handler I got :

the log :
nfo> app: BSP_BUTTON_0
                                                       

nfo> app: BSP_BUTTON_1
                                                       

nfo> app: BSP_BUTTON_2
                                                       

nfo> app: BSP_BUTTON_3
                                                       

nfo> app: BSP_BUTTON_2
                                                       

nfo> app: BSP_BUTTON_0

Any ideas?

Kind regards,

Hi Karl,

Why isn't responding to

bsp_button_event_handler on bsp.c, but only responding to bsp_event_handler in main.c ?

Hello again, Rixtronix

Thank you for your patience with this.

This looks for me like a possible fallthrough in a switch case handling, could this be the case?
I do not see any break statements at the end of the BSP_EVENT_KEY_2 case you have shared, at least.

I notice that you are not checking the returned error code from you calls to bsp_event_to_button_action_assign, please make sure to do so to see if they are succeeding.

I also notice that you are using the ant bsp init, bsp_btn_ant_init, could you elaborate on why you are using this, and what your intentions are for calling it multiple times in a row?
The bsp init function should only have to be called once.

Best regards,
Karl

Hi Karl,

}	

So I need to use only

 bsp_init

and don't have to use bsp_btn_ant_init, I took it from ANT example ?
