About the NVIC_EnableIRQ

[redfish]

     Hi  ,   

              If the softdevice had inited  (called sd_ble_enable()  ) ,     Can I  use the NVIC_EnableIRQ (or NVIC_DisableIRQ )   

    to enable/disable an interrupt ? 

            What is the difference between the sd_nvic_EnableIRQ and  NVIC_EnableIRQ ?                  

                 Thanks  a lot !

Hi.

If you have the SoftDevice enabled, you cannot use the NVIC_EnableIRQ or NVIC_DisableIRQ API, this is because it is restricted when the SoftDevice is enabled, as you can read here.

You then have to use the SoftDevice API for NVIC.

sd_nvic_DisableIRQ() and sd_nvic_EnableIRQ(), they corresponds to NVIC_DisableIRQ and NVIC_EnableIRQ in CMSIS.

Thanks your reply  !    Then I can use like this :

//  power on 

    NVIC_DisableIRQ(TIMER1_IRQn) ; 

 sd_ble_enable(&ble_enable_params);

  ....

 NVIC_EnableIRQ(TIMER1_IRQn);

   .......

 // softdevice is enabled , do somthing 

 sd_nvic_DisableIRQ(TIMER1_IRQn) ; 

myfunc1() ; 

sd_nvic_EnableIRQ(TIMER1_IRQn);

.....

You cant use NVIC_EnableIRQ(TIMER1_IRQn); after you have used sd_ble_enable(&ble_enable_params); (since you have enabled the SoftDevice here), you have to use the sd_nvic_EnableIRQ(TIMER1_IRQn); API after you enabled the SoftDevice.

OK , Thank you !
