Get TWI event address ( TWI + PPI)

[Alanarf]

Hello all.

I need to detect when  data is received on RX. I am planning to use it with PPI channel so i could instantiate a task to it. 

I tried to use  nrf_twi_event_address_get to get the address of event so i could assign to a PPI channel. But Kiel warns me that  Implicit declaration of function is invalid, and give me the error:  #20: identifier "nrf_drv_twi_event_address_get" is undefined, even though I have nrf_drv_twi, /hal/nrf_twi added in the path. 

So how can i get the address of TWI events and use it with PPI? 

Thank you

Hi,

it seems you're mistyping nrf_drv_twi_event_address_get (should be nrf_twi_event_address_get)

Hello Dmitry, thanks for reply.

My bad, replaced  nrf_drv_twi_event_address_get to nrf_twi_event_address_get and got new errors

Any help?
