Abstract
The present invention provides methods for operating data loggers and in particular, software techniques useful for controlling the critical functions of a low-power-battery-operated data logger. One method initializes various memory locations upon a detection of new firmware. Another method allows a processor system belonging to a data logger to receive a high baud rate data stream while being operated in a sleep mode. Yet another method provides a highly efficient process for estimating the remaining battery capacity of a data logger's primary power source. Finally, a method is provided for protecting volatile variables during a disruption of primary power. The protected variables are written to non-volatile memory using parasitic power only.
