https://devzone.nordicsemi.com/f/nordic-q-a/38278/logarithm-function-implementationHello, we are trying to implement PWM function with an incrementing/ decrementing duty cycle using a logarithmic function rather than linear function. Is there any predefined function for logarithmic operation? Also, what data types are available to denoteen-USTelligent Community 13Fri, 07 Sep 2018 11:59:39 GMThttps://devzone.nordicsemi.com/thread/147795?ContentTypeID=1Fri, 07 Sep 2018 11:59:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:437dff6c-0748-4cae-9ea4-86930fac4885Einar Thorsrud<p>Hi,</p> <p>There is no direct way to get a logarithmic function like this. However, you could calculate the samples of your logarithmic functions and store them in a large array. Then you could use the PWM peripheral to simply &quot;play out&quot; the samples using DMA. This requires a bit of space but has the benefit that you can generate any pattern you like.</p><div style="clear:both;"></div>
