Josh came over and we spent the day at my place trying to get the TLV1570 ADC (Analog to Digital Converter) to behave. Mistake after mistake, we eventually decided to give up on the complicated 8-channel part and order a simpler TLV1572 ADC instead, free samples courtesy of Texas Instruments. I dropped Josh back at his apartment, and carefully read the ADC instructions once more when I returned just to make sure that I had not missed something obvious. Oops. It turns out that I had the pins connected wrong all along!

Even though the ADC is still quite flaky, it works well enough now to where I think we can get a check off on Wednesday. I’m ready to get this project over with.
