A lot of 12V automotive systems have a logic low level near 3V. Having the analog reading is better than nothing but suboptimal.
I'm looking at a 5 V analog signal that is toggling between 4.7 and 1.6 V. The ability to set the voltage thresholds that determine what is considered low and high for digital readings would be helpful. This would allow for me to see these as digital values and use some of those measurement tools. I believe this concept is similar to what the original poster had suggested.
