As part of a larger product I am using 7.4V LiPo packs to power a unmanned ground vehicle. Part of the requirements of this project is that the battery voltage be monitored, due to the volatile nature of LiPo's when they drop under voltage. Because of this, I need to be able to read the Voltage level from the batteries and broadcast this information back to a ground station, the communications side however is already complete.
My goal is to employ an ADC0831 A/D converter to read the voltage levels, likely using a voltage divider to scale the voltages going to the Prop down to the correct levels (0-3.3V).
Searching around a bit, I found several examples of this being accomplished on the BS2 platform, employing the BS2 SHIFTIN functionality. Fortunately, thanks to the object exchange and Martin Hebel's BS2 Functions object I am fairly sure I can replicate the BS2 functionality on the Propeller, my goal being to model my voltmeter off of the attached BS2-orginated schematic.
In either case as I continue to tinker I figured I would see if anyone else out there has done this already using the Propeller and could offer any hints or suggestions.
