I am planning out a little project to control an intake manifold butterfly for my 2008 Honda Accord.
Currently, I have a generic ELM327 Wi-Fi OBD dongle for use with my iPhone to monitor a handful of PIDs while driving.
I am thinking of getting the Carloop Basic to constantly poll for RPM and set two GPIO lines either high or low depending on whether or not the RPM is above a certain number. The GPIO lines would control a DRV8871 motor driver.
It looks like the Photon would have some available digital output pins, but I'd like to confirm there are at least two outputs that I can use.
With an OBD splitter, could my wireless dongle and the Carloop be able to run at the same time, with a fast response rate?
I don't monitor my RPM with the phone app if that matters.
