EZR32WG 490MHz Wireless Starter Kit Introduction 1. Introduction 1.1 Description The idea behind the WSTK6223 is to provide a complete development platform for Silicon Labs EZR32 Wonder Gecko Wireless Microcontrollers. The core of the WSTK6223 is the Wireless Starter Kit (WSTK) Mainboard (BRD4001) which feature an on-board J-Link debugger, an Advanced Energy Monitor for real-time current and voltage monitoring, a Virtual COM port interface, and access to the Packet Trace Interface (PTI).

EZR32WG 490MHz Wireless Starter Kit Power Supply and Reset 4. Power Supply and Reset 4.1 MCU Power Selection The EZR32 Wonder Gecko MCU on the WSTK6223 is designed to be powered by three different sources: • Through the on-board debugger. • Through the EZR32's own USB regulator. • By a 3V Battery. B AT U SB AE M Selecting the power source is done with the slide switch in the lower left corner of the board. Figure Figure 4.
EZR32WG 490MHz Wireless Starter Kit Power Supply and Reset 4.4 MCU Reset The EZR32 MCU can be reset by a few different sources: • A user pressing the RESET button. • The on-board debugger pulling the #RESET pin low. • An external debugger pulling the #RESET pin low. 4.5 Board Controller Reset The Board Controller can be reset by removing and re-inserting the J-Link USB cable.
EZR32WG 490MHz Wireless Starter Kit Peripherals 5. Peripherals The starter kit has a set of peripherals that showcase some of the features of the EZR32 Wonder Gecko Wireless Microcontroller. Be aware that most EZR32 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. 5.1 Push Buttons and LEDs The kit has two user push buttons marked PB0 and PB1.
EZR32WG 490MHz Wireless Starter Kit Peripherals 5.2 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.
EZR32WG 490MHz Wireless Starter Kit Peripherals 5.4 USB Micro-B Connector The BRD4505B WSTK Radio Board is equipped with a USB Micro-B connector that is connected directly to the EZR32. The Radio Board supports operation in USB Device mode only, even if the target radio also supports USB Host mode. Figure 5.3 Radio Board USB Connector on page 8 shows how the USB lines are connected to the EZR32. Figure 5.3. Radio Board USB Connector silabs.com | Smart. Connected. Energy-friendly. Rev. 1.
EZR32WG 490MHz Wireless Starter Kit Peripherals 5.5 Si7021 Relative Humidity and Temperature Sensor The Si7021 I2C relative humidity and temperature sensor is a monolithic CMOS IC integrating humidity and temperature sensor elements, an analog-to-digital converter, signal processing, calibration data, and an I2C Interface.
EZR32WG 490MHz Wireless Starter Kit Advanced Energy Monitor 6. Advanced Energy Monitor 6.1 Introduction Any embedded developer seeking to make his embedded code spend as little energy as the underlying architecture supports, needs tools to easily and quickly discover inefficiencies in the running application. This is what the Simplicity Energy Profiler is designed to do.
EZR32WG 490MHz Wireless Starter Kit Advanced Energy Monitor 6.3 AEM accuracy and performance The Advanced Energy Monitor is capable of measuring currents in the range of 0.1 µA to95mA. For currents above 250 µA, the AEM is accurate within 0.1 mA. When measuring currents below 250 µA, the accuracy increases to 1 µA. Even though the absolute accuracy is 1 µA in the sub 250 µA range, the AEM is able to detect changes in the current consumption as small as 100 nA. The AEM current sampling rate is 10000 Hz.
EZR32WG 490MHz Wireless Starter Kit Board Controller 7. 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 EZR32 and the board controller in the form of a UART connection. The connection is enabled by setting the VCOM_ENABLE (PA12) line high, and using the lines VCOM_TX (PB3) and VCOM_RX (PB4) for communication.
EZR32WG 490MHz Wireless Starter Kit Board Support Package 8. 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. Using the BSP is not required, and the EZR32 is fully usable without the BSP. The BSP uses EZR32 peripheral USART2, Location 1 (TX pin PB3, RX pin PB4) on baudrate 115200-8-N-1 to communicate with the board controller.
