It is not impossible that the contouring that I observed on your photograph is caused by that configuration.
I'll do that, for sure...just a temporary chunk of code for this purpose...Klaas Robers wrote:Any way, if you build it, try to test it with a saw tooth as a digital input signal and check that there are no hick-ups in the output signal. From the past I know how difficult it is to get a smooth ramp, but it is possible.
