My application is read 3 ADC channel one by one and send this value to android app using NUS. For this i have use This Time drive Adc exmple but for this is very high power consumption and alsoen-USTelligent Community 13Thu, 23 Nov 2017 11:02:27 GMThttps://devzone.nordicsemi.com/thread/108596?ContentTypeID=1Thu, 23 Nov 2017 11:02:27 GMT137ad170-7792-4731-bb38-c0d22fbe4515:79a5b544-23f6-4857-a820-13c020e1d581vishal<p>Ya write, Thanks you so much....</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/108595?ContentTypeID=1Thu, 23 Nov 2017 09:05:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3d0e01fa-a649-4784-9d82-4374a0e4b6a3J&#248;rgen Holmefjord<p>Answered in your <a href="https://devzone.nordicsemi.com/question/172373/adc-conversion-using-4096hz-for-nrf52832-chip/">other post</a>.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/108594?ContentTypeID=1Wed, 22 Nov 2017 16:53:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8a12126d-85d0-485d-b13c-43ed7bab9933AmbystomaLabs<p>Basically anything that has a hardware register for an task/event can be tied to a PPI channel. So, in your application you would need to tie the RTC event compare or event overflow to the SAADC TASKS_START or TASKS_SAMPLE event via PPI. You will still need to have inited the saadc elsewhere and the result will still hit the callback handler. But this way the execution is all in PPI.</p><div style="clear:both;"></div>
