ECG 2 Click cannot function with NRF52840https://devzone.nordicsemi.com/f/nordic-q-a/73739/ecg-2-click-cannot-function-with-nrf52840Hi , I have real ECG device with 2 Click and I almost got NRF52840 with PCA10056 development board. I want to put the analog signal from the ECG device to the ADC on the development board (PCA10056) , so I use the example on the SDK of the NRF which isen-USTelligent Community 13Fri, 09 Apr 2021 12:35:08 GMTRE: ECG 2 Click cannot function with NRF52840https://devzone.nordicsemi.com/thread/304008?ContentTypeID=1Fri, 09 Apr 2021 12:35:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f1dd98c7-f63c-4006-b972-55c9b3eb541bnikola <p>ok i want to try with this example but how i want to connect the sensor pins?</p><div style="clear:both;"></div>RE: ECG 2 Click cannot function with NRF52840https://devzone.nordicsemi.com/thread/304003?ContentTypeID=1Fri, 09 Apr 2021 12:23:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f9838a91-99dd-408d-9594-d5ac44ac2e1dVidar Berg<p>Hi,</p> <p>The project configuration you have selected is meant for the setup described <a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/nrf51_setups_serialization.html">here</a> where you have 2 MCUs, and your ECG board does not fit into that architecture.</p> <p>I think it would be easier if you started with the more simple <span><a title="SPI Master Example" href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/spi_master_example.html?cp=7_1_4_6_37">SPI Master Example</a><span> first.
