2.1 P
ackage
The STEVAL-ISB011V1 demonstration board package includes the following:
Hardware content
– Demonstration board STEVAL-ISB011V1
Documentation
– User manual (this document)
– Schematics, Gerber files, BOM list
Microcontroller firmware
– Pre-programmed STM32F102C6 device soldered on the demonstration board
– Source code is available for the firmware.
2.2 Setting up the board
The Li-Ion battery monitor and charger can be set up as follows:
Connect the Li-Ion battery pack to the board with appropriate polarity across J14
Before connecting a battery, set the jumper between pin 1 and 2 of J3. This ensures
clearing of the RAM registers of STC3100 and indicates connection of a fresh battery.
For details refer to: jumper J3
The board can be powered up by a power adapter (5 V power supply), by connecting
the micro-B cable, or by battery
Ensure to connect the external power supply source if battery voltage is below cut-off
voltage (Cut-off voltage is set to 3.1 V by using STM MOSFET)
Switch SW7 is used to select between wall adapter or USB as the power source
To display battery parameters on the HyperTerminal, connect the micro-B cable and
open a new HyperTerminal window. Details are given in Section 5.4: HyperTerminal
settings
If external power source is present, the internal charger can be used to charge the
battery using switch SW8
An external charger can also be connected directly across J12. Switch SW8 is used to
select either internal or external charger
A welcome message (STC3100 battery monitoring demo) is displayed on the LCD
during startup. Once again, place the jumper between pin 2 and 3 of J3. For details
refer to: jumper J3
Now use the navigation keys (SW1, SW2, SW3, and SW4) to scroll through the menu.
