https://devzone.nordicsemi.com/f/nordic-q-a/19190/saadc-and-s140---nrf-pdkMy code hit weak handler when I try to modify the examples/peripheral/saadc to run with softdevice s140 on nrf82840 PDK. All I did was adding a BLE Stack initialization before calling saadc_init , saadc_sampling_event_init and saadc_sampling_event_enableen-USTelligent Community 13Tue, 24 Jan 2017 10:03:18 GMThttps://devzone.nordicsemi.com/thread/74328?ContentTypeID=1Tue, 24 Jan 2017 10:03:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1dc16a19-02fc-4c53-ba84-740d33dc9f62Ole Bauck<p>Have you changed the timer instance to use another timer than TIMER0?</p> <pre><code>static const nrf_drv_timer_t m_timer = NRF_DRV_TIMER_INSTANCE(0); </code></pre> <p>TIMER0 is used by the SoftDevice and cannot be used by the application, see <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s132.sds/dita/softdevices/s130/sd_resource_reqs/hw_block_interrupt_vector.html?cp=2_3_0_0_6_0">here</a> (SoftDevice S132, but also applies to S140).
