https://devzone.nordicsemi.com/f/nordic-q-a/511/showing-uart-strings-in-keilHello, I am using an nRF51822 Development Kit. I am trying to run pca10001/board/uart_example (with simple_uart) using the UART serial viewer built into the Keil programming software (in debugging mode). So far, I cannot get these UART windows to displayen-USTelligent Community 13Fri, 27 Sep 2013 08:58:54 GMThttps://devzone.nordicsemi.com/thread/2664?ContentTypeID=1Fri, 27 Sep 2013 08:58:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e1efcc81-cffd-4e8d-a6c0-f96e4f5a6177Ole Morten<p>As far as I can see from Keil&#39;s documentation <a href="http://www.keil.com/support/man/docs/uv4/uv4_db_dbg_serialwin.htm">here</a>, these windows are meant to be used only for simulated CPUs, and are as such not applicable for hardware debugging with the nRF51822.</p> <p>As for the Debug (printf) viewer, this requires trace hardware in the chip, and the nRF51822 does not have this. You&#39;ll therefore have to use a separate terminal program to receive UART data from the nRF51822.</p><div style="clear:both;"></div>
