Source Code History
V1-04
- program is identifed as Sparrow1 with a version of 1.01 and a build date of 15-Mar-2008 during the playback phase
- code and data storage uses 39% of the Basic Stamp 2's EEPROM space (at 2K Bytes)
- data storage can log 120 events at roughly 1.5 to 2 seconds per event
- each event takes up 2 bytes
- playback of data run has the format of SP1, event number, raw data in decimal, raw data in 9 bit binary
- temperature in Centigrade can be found by dividing the raw data in decimal by 2
- start delay of 25 seconds from the time pushbutton A is pushed to when the program is recording data
