ECG 2 Click cannot function with NRF52840

[nikola]

Hi , 
 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  is ble_app_hrs (ble_app_hrs_pca10056_s140_spi) but it does'nt function and I don't understand what is the problem 

here you find the sensor  that I am using

And here you find the connections that I am making on NRF52840 :

CS ==> P1.13

SCK==> P0.27

SDO==> P0.26

SDI==>P0.02

GND==>GND

5V==>5V

DRD==>P1.15

PWD==>P1.14

Reset==>P1.01

I am Folowing Pins already exists on Pca10056.h like this 

 

Refering on the Pinout  GPIO  of the sensor : 

Is there any way to do that ?

Hi,

The project configuration you have selected is meant for the setup described here where you have 2 MCUs, and your ECG board does not fit into that architecture.

I think it would be easier if you started with the more simple SPI Master Example first. You can migrate the driver code to one of the BLE examples afterwards.

Best regards,

Vidar

ok i want to try with this example but how i want to connect the sensor pins?
