1 Usage
1.1 Placement
This board is intended for use with the EFM32 Gecko Development Kit.
1.2 Reset Button / Reset LED
When pressed, the reset button resets the EFM32 device. When reset is asserted, a red led next to the
button is lit. A filter is connected to the reset line in order to reduce bouncing.
1.3 LEDs Indicating Power
The two green LEDs indicate poweron the VMCU and 3.3V nets, respectively.
1.4 Crystal Oscillators
The board features one 32.768kHz and one 32MHz crystal. These are connected through 0-ohm resis-
tors to the respective inputs of the low-frequency and high-frequency crystal oscillators of the EFM32.
Using these instead of the internal RC-oscillators will ensure higher frequency accuracy. However, if the
reduced accuracy is acceptable, theese lines can be used as normal IO-lines instead by removing the
0-ohm resistors. In order to export these IO lines to the Kit mainboard, insert resistors for connection to
the EFM32_A bus. See schematic for details.
1.5 Kit Connection
It is possible to access the board controller on the Kit mainboard for example to turn LEDs on or off, read
push button status or connecting the EMF32 to specific hardware on the mainboard. The access may
either through SPI or the parallel interface (EBI), and the access mode is signaled to the board controller
by asserting one of two dedicated signal lines. It is recomended to use the Board Support Package
(BSP) for access to the mainboard. Please see the Kit user guide for furhter description of the BSP.
1.6 LCD
The LCD is a 164 segment display designed for 1/4 Duty, 1/3 bias. The operating voltage is 3.0V and the
frame frequency is 64 Hz. Since the EFM32 only supports 160 segments, the Celsius and Fahrenheit
along with uA and mA segments are not connected. However, they may be made available by moving
a 0-ohm resistor. See schematic for details. Please see the LCD software example project for details
on how to use the LCD. For details on segment connections see the attached mapping table and LDC
illustration.
1.7 EBI / LCD Configuration
Since many of the IO lines used by the EBI are also used by the LCD, the board is either configured to
route the IO lines to the LCD connector or to the Kit mainboard. The configuration is determined by a
set of 0-ohm resistor arrays. This configuration may be altered my moving the arrays. See schematic
for details.
