I built most of it for Arduino, as ...en-USTelligent Community 12https://community.element14.com/members-area/personalblogs/b/nico-tewinkel-s-blog/posts/frdm-kl25z-and-tmp36-sensorThu, 11 Jul 2013 20:38:13 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:6ecb03c4-69d4-4218-8d99-719c9e44cd67vsluiter1<p>Nico,</p><p>Others have found similar problems: <a class="jive-link-external-small" href="http://mbed.org/forum/mbed/topic/628/?page=1#comment-3178" rel="nofollow ugc noopener" target="_blank">http://mbed.org/forum/mbed/topic/628/?page=1#comment-3178</a></p><p>Maybe you could set the reference voltage to an internal reference to see whether that helps; with no&nbsp; API call for that, it would involve digging into the Freescale registers.</p><p>Otherwise use a RC filter (small R, large C to quickly fill the Sample-and-Hold capacitor) to buffer the output of your sensor.
