https://devzone.nordicsemi.com/f/nordic-q-a/34537/timer-hal-driver-sdk15Hi, I am trying to run a simple LED blinking program using timer 0 using HAL library. in functions such as nrf_timer_bit_width_set (NRF_TIMER_Type *p_reg, nrf_timer_bit_width_t bit_width) nrf_timer_frequency_set (NRF_TIMER_Typeen-USTelligent Community 13Tue, 29 May 2018 11:48:22 GMThttps://devzone.nordicsemi.com/thread/133799?ContentTypeID=1Tue, 29 May 2018 11:48:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0159ce0d-53b5-40ea-8127-0ae62760a14dNiranjan Pandian<p>Thank you.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/132768?ContentTypeID=1Tue, 22 May 2018 12:49:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:375662a0-ba80-4d9a-93c9-773419149a30J&#248;rgen Holmefjord<p>Hi,</p> <ol> <li>NRF_TIMER_Type is defined in the MDK. For nRF52832, it is defined in the file nrf52.h, which can be found in&nbsp;nRF5_SDK_15.0.0_a53641a\modules\nrfx\mdk\nrf52.h. You should use the defined symbols&nbsp;NRF_TIMERx, where x is the timer number (0-4 for nRF52832), for this argument when using the HAL functions.</li> <li>There are no file nrf_timer.c in the SDK, only a header file: nrf_timer.h. This HAL driver implementations can be found in&nbsp;nRF5_SDK_15.0.0_a53641a\modules\nrfx\hal.</li> </ol> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
