The Demo Meter application enters a low power mode (back-up mode) in two ways:

  • When the user types the command “DCB” in the console.

  • When the “Scroll-up” button is pressed and, then, without releasing it, “Scroll-down” is also pressed.

The system wakes up when the user pushes the “TAMPER” or “FWUP” buttons if the main power supply was restored.

NOTE: The user can easily change the code to add other transition modes to low power mode. In some cases, it could be useful to switch to low power mode when a power outage is detected or depending on the micro controller voltage supply monitor information. These transitions could be combined with writing on external memory to store relevant data.
