Making an altimeter in under 2 hours

Well, it's technically an altimeter. But I will not be jumping out of a plane with it any time soon. Yesterday I received the shipment from SparkFun. I soldered headers onto all of the PCBs. I positioned them on a breadboard, and had the discipline to walk away. This morning I got up at 5am and got started. I've managed to accomplish 6 of this weeks development goals.

  1. read altitude from MPL3115A2
  2. read temp from MPL3115A2
  3. write data to OpenLog
  4. set current time on RTC
  5. read time from RTC
  6. illuminate a segment via shift register

That's pretty amazing because I only expected to accomplish the first 2.
