Not able to find SAADC example setup (example_board_setup_a.jpg) picture

[Tajpeer]

Hello All,

Sorry for writing this.

It may be a simple thing which I am not able to find even after looking in the SDK so I am writing this.

I want to run SAADC example code on my nRF52832 eval kit. I have got the example code in example as I am using SDK 16.0.0. But couldn't get the set up image as explained in the main.c file.

Can someone please help me to find the right image for this? Which helps me to look the setup images for other examples as well.

Thanks in advacne.

Hello,

Sorry for writing this.

There is absolutely no need to apologize or be sorry for posting in the forum, no worries at all! :)

You are absolutely correct - there is no other mention of this in neither Infocenter nor the SDK itself - in fact, this line has somehow survived years of scrutiny and multiple SDK revisions, and should have been removed from the example's source code a long time ago, keenly spotted - well done!
I have created an internal ticket on this to have it removed, as it should have been many years ago. Thank you for pointing this out.

The story behind this line is that the hardware setup of the Development Kit used to be a lot more convoluted back in the day, and the picture was there to detail how it should look for most examples.
Luckily, we are passed that now, and the Development Kit in its default state goes a long way to showcase the different examples - much less convoluted configuration required, if anything at all.

The good news is that this picture is now obsolete - all you need to do to run the example on your nRF52 Development Kit is described in the SAADC example documentation.
In essence, program your device and open up a serial monitor for the COM port of your device.
There, you should see messages start coming in with the measurements taken on AIN0 of the DK. If you short this to either VDD or GND you should see this reflected in the measurements output to the serial monitor.

Please do not hesitate to ask if anything still should be unclear, or if you should encounter any other issues or questions! 

Best regards,
