6.3. Data Logger Modes and Indicator LEDs
The data logger has three modes of operation shown in Table 1:
The Logging Only mode is the lowest power mode and is the mode in which the data logger spends most of its
operating life. The primary goal of this mode is to prolong battery life and keep the data log up to date. The system
enters this mode when it is powered from the battery and the last reset was a power on reset or other reset not
caused by the reset pin. In this mode, the Yellow LED will blink when the S2 switch is pressed to indicate that the
system is in its lowest power mode.
The Logging + UART mode is entered when powered from the battery and a pin reset occurs. A pin reset is
generated on the C8051F912 Daughter Card when the ToolStick Terminal is connected. In this mode, the device
prints a log summary to the screen and blinks the Red LED when the S2 switch is pressed. This mode preserves
battery life, but it requires the MCU to stay in active mode while transmitting information over UART.
When the power source is set to ToolStick Power, the data logger will enter Interactive Mode. Since the MCU is
powered from the ToolStick Base Adapter, it runs at full speed without entering a low power mode. It constantly
monitors the potentiometer ratio, the capacitive touch sense switch oscillation period, and the current temperature.
Since the battery is disconnected when being powered from the ToolStick Base Adapter, the MCU cannot measure
the battery voltage. When S2 is pressed, the system toggles between displaying a log summary and interactive
content in addition to blinking both the Yellow and Red LEDs.
mode, the ToolStick Terminal is continuously refreshed with information about the number of seconds remaining
until the next Log entry, the current potentiometer ratio (%), the oscillation period of the Capacitive Touch Sense
Switch (SYSCLKs), and the current temperature (degrees C). Press the S2 switch again to return to the log
summary.
