Page 6: Power Supply And Reset
Power Supply and Reset 4. Power Supply and Reset 4.1 MCU Power Selection The Laser Bee MCU on the EFM8LB1-SLSTK2030A is designed to be powered by three different sources: • Through the on-board debugger. • By a 3 V Battery. - Page 7 UG126: EFM8LB1-SLSTK2030A User's Guide Peripherals 5. Peripherals The starter kit has a set of peripherals that showcase some of the features of the EFM8 Laser Bee microcontroller. Be aware that most EFM8 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.
- Page 8 UG126: EFM8LB1-SLSTK2030A User's Guide Peripherals 5.2 Joystick The kit has an analog joystick with 8 measureable positions. This joystick is connected to the EFM8 on the P1.7 pin and uses different resistor values to create voltages measurable by the ADC0.
- Page 9 UG126: EFM8LB1-SLSTK2030A User's Guide Peripherals 5.3 Memory LCD-TFT Display A 1.28-inch SHARP Memory LCD-TFT has been added to the board to enable interactive applications to be developed. The display has a high resolution of 128 by 128 pixels and consumes very little power. It is a reflective monochrome display, so each pixel can only be light or dark, and no backlight is needed in normal daylight conditions.
- Page 10 UG126: EFM8LB1-SLSTK2030A User's Guide Connectors 6. Connectors 6.1 Breakout Pads Many of the EFM8's pins are routed out to "breakout pads" at the top and bottom edges of the kit. A 2.54 mm pitch pin header can be soldered in for easy access to these pins. Most I/O pins are available, with the exception of pins used to drive the LCD.
- Page 11 UG126: EFM8LB1-SLSTK2030A User's Guide Connectors 6.2 Expansion Header On the right hand side of the board an angled 20-pin expansion header is provided to allow connection of peripherals or plugin boards. The connecter contains a number of I/O pins that can be used with most of the Laser Bee's features. Additionally, the VMCU, 3V3 and 5V power rails are also exported.
- Page 12 UG126: EFM8LB1-SLSTK2030A User's Guide Connectors Note: This table only sums up some of the alternate functions available on the expansion header. Consult the EFM8LB12F64E data sheet for a complete list of alternate functions. 6.3 Debug Connector This connector is used for Debug In and Debug Out (see chapter on Debugging).
- Page 13 UG126: EFM8LB1-SLSTK2030A User's Guide Connectors 6.4 Direct Debug Connector This connector (J103) is used for directly debugging the EFM8 using an external debug adapter (see chapter on Debugging). This is especially useful for debugging the MCU on the STK board when the part is battery powered or powered by an external supply.

More details about AEM and its operation can be found in the STK User Guide. Note that AEM will measure the current for all circuitry connected to VMCU, including the STK MCU and the CPT device. Figure 8.1. Measuring EFM8LB1-SLSTK2030A Current Using AEM 8.1 Usage The AEM data is collected by the board controller and can be displayed by the energyAware Profiler, available through Simplicity Stu- dio. - Page 16 UG126: EFM8LB1-SLSTK2030A User's Guide Advanced Energy Monitor 8.2 AEM Theory of Operation In order to be able to accurately measure current ranging from 0.1 µA to 50 mA (114 dB dynamic range), a current sense amplifier is utilized together with a dual gain stage. The current sense amplifier measures the voltage drop over a small series resistor, and the gain stage further amplifies this voltage with two different gain settings to obtain two current ranges.

Board Controller The kit contains a board controller that is responsible for performing various board-level tasks, such as handling the debugger and the Advanced Energy Monitor. An interface is provided between the EFM8 and the board controller in the form of a UART connection. The connection is enabled by setting the EFM_BC_EN (P2.2) line high, and using the lines EFM_BC_TX (P0.4) and EFM_BC_RX (P0.5) for...
- Page 18 10. Debugging The EFM8LB1-SLSTK2030A contains an integrated debugger, which can be used to download code and debug the Laser Bee EFM8 MCU. In addition to programming the MCU on the kit, the debugger can also be used to program and debug external Silicon Labs EFM8 devices.
