CPU freq Testhttps://devzone.nordicsemi.com/f/nordic-q-a/59959/cpu-freq-testWe seem to be seeing slowness in a bare metal implementation. We would like to confirm the nrf52832 CPU speed. How can this be confirmed from within the codebase and/or logger ?en-USTelligent Community 13Wed, 08 Apr 2020 13:39:06 GMTRE: CPU freq Testhttps://devzone.nordicsemi.com/thread/244094?ContentTypeID=1Wed, 08 Apr 2020 13:39:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:665535c3-7b3a-4471-8b88-c5bdedea9d29beadon<p>thank you, this is exactly what I was looking for.</p><div style="clear:both;"></div>RE: CPU freq Testhttps://devzone.nordicsemi.com/thread/243984?ContentTypeID=1Wed, 08 Apr 2020 07:18:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:81401bee-f55a-45e6-95fa-debde6fd990cAmanda Hsieh<p><span>Hi, </span></p> <p><span>The nRF52832 CPU clock speed is 64 MHz.
