Start stop button ?

user91908

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,

    Hello,

    I am not sure what you are doing with the actual_state and BSP_INDICATE_FIRST, but perhaps you could use the bsp_event_to_button_action_assign function to assign a bsp event like BSP_EVENT_KEY_0 to a buttonpress, and then in the handler check if the state is either active or not, inverse it, and perform some other function?
    Something similar to this:

    #define STATE_ON 1
#define STATE_OFF 0
..
    case BSP_EVENT_KEY_0:
        if(state)
        {
            OFF_function();
            state = STATE_OFF;
        }
        else
        {
            ON_function();
            state = STATE_ON;
        }
..


    Best regards,
