STM32F4 low-power application case

AN4365

30/35

DocID025303 Rev 2

Figure 16. Hardware connections

To run the application on STM32F4 devices, the following steps are required:

Connect the two I2Cs of the two devices.

Power both discoveries through mini USB connectors.

From Windows, launch the adequate toolchain and load the two boards with Master

and sensor programs.

Connect the multimeter to the desired board instead of each discovery Idd jumper

(JPx) as described in Table 2.

Press the master user button to start the application and then the multimeter displays

the average power consumption of each device.

Note:

The R30 resistance should be removed from the MB1115B discovery.

The R31 and R34 resistances should be removed from the MB997C discovery.
