IDD

Overview

The IDD module application measures and displays in real time the MCU current

consumption depending on the selected power mode. The current is measured and

calculated using a second microcontroller from the STM32L1 Series on the board.

Figure 9. IDD application menu structure display

Value is the Idd measurement result displayed for 2.5 seconds either in milliampere (mA),

microampere (µA) or nanoampere (nA).
