Another quick experiment w/ the CircuitCo Educational BoosterPack. Measures capacitance (< 1nF) and inductance using LC tank frequency measuring method. Measures capacitance (> 1nF) with time-to-charge method. Measures (or rather attempts to measure) capacitor ESR values by pulse injecting currents through capacitors. Bare minimal component count, experimental hookup. I called this a "Meter Template" instead of a "Meter" as I consider this hookup as a base to develop a "Full" meter. There are quite a few things "missing" when compare w/ other common designs you can find on the internet, that affects accuracy and usability. Breadboard is no good for capacitance measuring, and LC tanks. Instead of using transistors to source and sink currents through test subjects, I drive them direct (close to 30mA on one pin). No relays to switch inputs, have to use your hand. No relays / switches to map multiple ranges components. One range for all (well, we have high and low capacitance). And it's fully functional with not-too-bad accuracy. Schematic and additional write-ups will follow.
I found a post on the TI E2E community asking questions about the LCD on the educational boosterpack. Someone posted some code for energia and it worked perfect. I took the code and "translated" it to non energia. Here is the forum post. Also here is documentation for the LCD itself from the manufacturer website (PDF). Right now this code prints "hello 43oh.com" . I am going to play with it more later tomorrow. If it is messy code I apoligize, long day at school work in addition to getting use to this platform..
