hardware timer driver problem

[Davide]

Hello everybody, I'm trying to make TIMER1 working on nRF51822 together with softdevice. In particular I would like to drive an interrupt line that goes to another microcontroller and I need to drive it low 100-200us after an SPI event occour. Then I've decided to use an hardware timer that is started by the SPI event, when the timer ends the ISR has to be executed and inside ISR the pin is driven to zero level. Nothing complicated...

I've started from Timer example and I've copied almost all that main.c inside my project (adding references and includes that was missing in my main). I've changed the timer form 0 to 1 (if I'm not wrong timer0 is used by the softdevice) and i've enabled timer1 in ble_drv_config.h.

But I'm getting an error, during linking nrf_drv_common_irw_enable symbol is undefined.

Any idea how to fix? Do I forget to do something? Thanks, Davide.

PS: I'm using keil and 8.0 skd

solved! I forgot to include nrf_drv_common.c file inside my project. I don't know if timers are working now, but the project compile without problems.

Bye
