4 Power supply
4.1 USB
The EFM32-G8XX-STK can get its power from the standard USB mini port. The MCU voltage will be
3.15 volts when USB is connected.
4.2 Battery
There is a socket for a 20mm coin cell battery, which can be used to power the kit. When the USB is
disconnected and the battery connect switch is turned on, the EFM and its peripherals is powered by
the battery. The VMCU voltage is 2.85 or lower when powered by the battery, depending on the battery
voltage. There is a 0.15V drop down from the battery voltage. The board controller/AEM is not powered
by the battery, so the BSP software support library cannot be used on battery power.

6 Peripherals
The starter kit has a set of peripherals that showcase some of the features of the EFM32G.
Be aware that most EFM I/O routed to peripherals are also routed to the breakout pads. This must be
taken into consideration when using the breakout pads for your application.
6.1 Pushbuttons
The kit has two user pushbuttons marked PB0 and PB1. They are connected to the EFM, and are
debounced by RC filters with a time constant of 1ms.
6.2 LEDs
There are four LEDs on the kit marked LED0 to LED3. An active high on the respective pins will light
the LEDs.
6.3 LCD

7 Advanced Energy Monitor
7.1 Usage
The AEM data is collected by the board controller and can be displayed by a PC application. For instance,
the "Gecko commander" utility contains a "power" command which can dump power data to file. A GUI
application for displaying power usage will be available for download from the Energy Micro download
section later.
7.2 AEM theory of operation
In order to be able to measure currents ranging from 0.1uA to 50mA (114dB dynamic range), two current
sense amplifiers are utilized. The amplifiers measure voltage drop over a small series resistor and
translates this into a current. Each amplifier is adjusted for current measurement in a specific range.
The ranges for the amplifiers overlap and a change between the two occurs when the current is 200uA.
To reduce noise, averaging of the samples is performed before the current measurement is presented
in the AEM GUI.
During startup of the kit, a calibration of the AEM is performed. This calibration compensates for the
offset error in the sense amplifiers.
7.3 AEM accuracy and performance
The Advanced Energy Monitor is capable of measuring currents in the range of 0.1uA to 50mA. For
currents above 200uA, the AEM is accurate within 0.1mA. When measuring currents below 200uA, the
accuracy increases to 1uA. Even though the absolute accuracy is 1uA in the sub 200uA range, the AEM
is able to detect changes in the current consumption as small as 100nA The measurement bandwidth
of the AEM is 60Hz when measuring currents below 200uA and 120Hz when measuring currents above
200uA. The table below summarizes accuracy of the two current sense amplifiers in different ranges.

8 Board controller
The control MCU can act as a board controller (BC). There is a UART connection between the EFM and
the BC. The connection is made by setting the bc_en line high. The EFM can then use the BSP to send
commands to the BC. When bc_en is low, bc_tx and bc_rx can be used by other applications.
To use the board controller for your application, the Board Support Package (BSP) must be installed.
See the BSP chapter to find out how.
Note
The board controller is only available when the STK is powered by USB.

Preliminary
...the world's most energy friendly microcontrollers
9 Board Support Package
The Board Support Package (BSP) is a set of C source and header files that enables easy access to,
and control over some board specific features.
Compared to the Energy Micro development kit, the functionality is limited. Unless you need/want some
of the functions contained in the BSP, there is really no need to include or use it. The EFM32 in the
Starter Kit can be fully usable without BSP support, and you can use all peripherals in the
C:\Program Files\Energy Micro\EFM32 Gecko DK\boards\EFM32_Gxxx_STK\drivers
folder without the BSP.
The BSP use EFM32 peripheral UART0 (TX pin PE0, RX pin PE1) on baudrate 115200-8-N-1 to
communicate with the board controller.
Note
The BSP is only functional when the Starter Kit is USB-powered, using these function calls
under battery power will give unpredictable results.
9.1 Installation location
When installing the complete software package for the kit, the BSP will be installed under the main
installation directory, typically in a location such as
C:\Program Files\Energy Micro\EFM32 Gecko DK\boards\EFM32_Gxxx_STK\bsp\
or something similar (depending on your OS/Windows version). All files in the board support package
is prefixed by stk.
9.2 Application Programming Interface
To use the BSP, include the Starter Kit header file, like this:
#include "stk.h"
All functions in the BSP are prefixed with STK_. The main initialization routine is defined as
void STK_Init(void);
and must be called before any access to the STK-functions. This function call will setup the UART
communication channel with a 115800 baud rate. This baud rate depends on the current core clock, so
correct clock configuration should be set before calling this function.
bool STK_Ready(void);
Returns true if the board controller is responding. A non-responding board will either return false, or
hang (i.e. if the EFM32 is powered by the CR2032 battery cell).
float STK_Current(void);
2010-04-09 - REVISION
10
www.energymicro.com
Preliminary
...the world's most energy friendly microcontrollers
Returns instant current usage in milliamperes.
float STK_Voltage(void);
Returns instant voltage (VMCU) reading in volt.
bool STK_EnergyMode(uint8_t em);
Informs the board controller about the Energy Mode (sleep mode) we are going into. This information
can be used by the board controller to present a richer visual graph for illustrating what the EFM32 is
currently doing.
In addition to these main functions, full documentation of the complete API is included in the Doxygen/
HTML documentation of the installed package.
9.3 Example Applications
Under the EFM32_Gxxx_STK/examples folder in your installation directory, you will find an example
program using the BSP, with corresponding project/Makefiles for the supported IDEs.
9.4 How to include in your own applications
The easiest way to include the BSP in your application is to base your work on the example application
that use the BSP. The following items are recommended for correct configuration:
1. Make sure you define the correct part number (i.e. EFM32G890F128) as a preprocessor defined
symbol
2. Make sure you define the correct part number (i.e. EFM32G890F128) for your project file
3. Add and include the EFM32_CMSIS-files (startup_efm32.s, system_efm32.c, core_cm3.c) to your
project
4. Add and include _all_ BSP package .c-files, with the stk-prefix to your project
5. Configure include paths to point at the CMSIS/CM3/CoreSupport and CMSIS/CM3/DeviceSupport/
EnergyMicro/EFM32 directories
6. Configure include paths to point to the EFM32_Gxxx_STK/bsp directory
Make sure you call "STK_Init()" early at startup, and you should be all set.
9.5 Chip errata
Early versions of the development kit are shipped with EFM32 Engineering Samples on the MCU
modules. There has been updates to configuration and reset values that needs to be configured correctly
on these early parts. We recommend always starting your application with a call to
#include "chip.h"
void CHIP_init(void);
to ensure correct and stable behavior. See the BSP examples for details. We recommend also to
download and read the latest errata from the Energy Micro website for your part number.

11 Debugging
The EFM32-G8XX-STK has an on-board debugger, and it can be used in different ways to debug the
EFM, both on and off kit. Below are descriptions on the different modes. Check the configuration chapter
to find out how to change the debug setting.
Table 11.1. Debug modes
Mode
Description
Debug MCU
In this mode the on-board debugger is connected to EFM on the EFM32-G8XX-STK.
Debug IN
In this mode the on-board debugger is disconnected, and an external debugger can be connected to
debug the EFM on the EFM32-G8XX-STK.
Debug OUT
In this mode the on-board debugger can be used to debug an EFM mounted in your own application.
11.1 Debugging during battery operation
When the EFM is powered by the battery (i.e. the USB is disconnected), the on-board debug functionality
is not available. To enable debugging in this mode, connect an external debugger (e.g. another EFM32G8XX-STK) to the debug pads in the bottom right corner of the EFM32-G8XX-STK. These pads are
connected directly to the EFM32 debug interface.
Note
When the on-board debugger is active, a current of approximately 1.6uA will be added to the
AEM measurements.
