01:38 <set_> Sorry...I am without words for what to do unless the "ranger" needs an ADC peripheral.

01:38 <set_> The source they give is for other boards but can be ported (somehow).

01:38 <set_> But...they use GPIO supposedly.

01:40 <set_> They have a GPIO in and GPIO out on the same pin...blah.

01:43 <set_> So, here is some class for the range: https://pastebin.com/MzguuAXW

01:45 <set_> Does anyone think using a GPIO pin for the "signal" on the Ultrasonic Ranger is possible or should I look elsewhere for a different peripheral?

13:07 <outrageous> set_: Seems unlikely that it would just be using GPIO. Would be complicated to deliver a value that way. I imagine that either it would be ADC or some kind of bus.

15:42 <set_> That is what I gather from the way their source keeps calling other files which led to adc.h.

15:42 <set_> We shall see...
