August 21, 2015: Not too much exciting going on. I've been reviewing the schematic and layout and fine-tuning everything getting ready to order. I also just today looked at the memory map as read by my phone. I was hoping it would be very obvious where the sensor value was getting communicated in the RFID memory. It's not clear to me at all. I read the tag, turned the potentiometer to change the analog value, and read the tag again. I compared the two logs and not a thing is different. I am a bit worried that I'm going to have to dive pretty deeply into an Android app to read the right values. I was hoping it would be easy. I do know I can clearly see a difference running the TI evaluation app with a TI USB reader EVM. Unfortunately, TI does not appear to have provided the source for that evaluation software, so I don't know what it's doing.
