All, on searching the internet, I stumbled upon a simple filter circuit that helps convert a PWM signal from an arduino or other maker board to relevant voltage level based on the duty cycle of the PWM. This could in theory then allow the Axo to read this via the Analogue Inputs. Just a thought as a simple way of passing values from an arduino to Axo. Note that I am already aware of the need to adjust the ref voltage from 5v to 3.3v. Anyone doing this already ? or any tips to improve the filter for less ripple ?
