Combing the PWM most significant byte with the Dpot least significant byte to provide 16-bit resolution, monotonicity, and linearity.

Despite having access to an oscilloscope, [Brian] aka [schoolie] has come up with his own method for measuring PWM period and duty cycle without a scope, just in case there’s ever a PWM emergency!

PWM is a simple, cool, cheap, cheerful, and (therefore) popular DAC technology. Excellent differential nonlinearity (DNL) and monotonicity are virtually guaranteed by PWM. Also guaranteed are a stable ...
