R1-1-8: • Changes measurement system so that sensor input averaging of the sensor during a reading is now only one total measurement, this reduces the chance of SDI-12 sensors resetting values and recording that incorrect value, this was found predominantly with SDI-12 sensors that work on the principle of cumulative reading between measurements such as Rain Gauges. R1-1-7: • Tweaks to the Watch Dog and Super Visor Timers to reduce the likelihood of measurements stopping due to “measurement initialization error” for when a measurement configuration with a large number of variables from sensors was exceeding the waiting time previously. R1-1-5: • Fixes issue relating to scheduler that caused missing data. R1-1-1 to R1-1-4: • Fixes possibility of SDI-12 bus power being stuck on when measurements are stopped, reducing the possibility of excess battery draw and battery low voltage failure. • Fixes warning glitch incorrectly reporting “Low Power” in datafile. • Fixes an issue where an update of channel configuration via Combined Instrument Software can cause SDI-12 bus power to turn on and remain on even after measurement is complete. R1-1-0: • Improvements to SD Card power handling and external power supply handling. • Adds CRC feature and toggle option to SDI-12 Logger for improving data integrity verification. • Bug fix for an issue which was causing a file with corrupt information to be created when the instrument starts up with a low voltage external power supply. R1-0-1: • Initial Release firmware for SDI-12 Logger
