EFM8SB1 is a new generation of 8-bit MCU series products launched by Silicon Labs, which is based on the 8051 kernel, designed for ultra-low power, capacitive touch applications, and is ideal for IOT products. Today I have got the Silicon Labs EFM8 Sleepy Bee entry suite, which evaluates and develops extremely low power applications on the EFM8 Sleepy Bee MCU, and can also be used to assess EFM8SB1 types of devices.
The kit includes the most functional EFM8SB10F8G MCU in the capacitive induction series with a running speed of up to 25 MHz. The EFM8SB10F8G MCU includes 8 KB of flash memory and 512 B RAM, as well as 14 capacitive induction channels. The SLSTK2010A can quickly open with the official Simplicity Studio, source code is available in Silicon Labs home SIMPLITITETE, allowing developers to build and run their own design.
Unpack
The development kit gets, the outer packaging has been designed with a white background and logo, it looks relatively simple.
There is a large container representative of EFM8, the upper left corner of the box is LOGO of Silicon Labs. We open the box and see the development boards and accessories.
Remove the things inside, including the development board, Mini USB line button battery, etc.
The brightest is the Slstk2010a development board to come to a front view.
The SLSTK2010A is an EFM8 Sleepy BEE EFM8SB1 microcontroller. The kit contains several buttons and LEDs, capacitive touch pulleys, and ultra-low power LCD-TFT display, with a J-Link debugger.
The SLSTK2010A has the following features:
EFM8SB10F8G MCU with 8 KB Flash and 512 B RAM
Advanced power monitoring system
Integrated SEGGER J-LINK USB Debugger / Simulator with Debug Function
20-pin expansion head
I / O expansion pin
Power supplies include USB and CR2032 batteries
2 user buttons, 2 users LED
1 rocker button
1 capacitive touch pulley
Ultra low power 128x128 pixel Memory-LCD
32.768kHz high precision crystal
External debugger interface
The back of the development board is mainly silk screen version, serial number and factory dates, and more.
Let's take a picture of MCU, you can see the MCU model is EFM8SB10F8G, and there is a small bee on the MCU.
EFM8SB10F8G is the MCU of the Sleepy BEE product range, which is the world's most energy-saving small package and features a multi-purpose 8-bit microcontroller. The EFM8SB10F8G product line features an efficient 8051 core with 14 high-quality capacitance sensing channels and high-precision simulation. Mainly has the following highlighting:

Demonstration and test
Silicon Labs provides a very nice integrated development environment for MCUs Simplicity Studio, which is also a demonstration for the Silicon Labs EFM8 Sleepy BEE with Simplicity Studio.
First installing Simplicity Studio, the development environment is an Eclipse framework, which is not elaborated, open Simplicity Studio.
Plug in the development board, the software will prompt the installation device, where the department selects the corresponding MCU model EFM8SB10F8G.
Then select the corresponding SDK installation
Waiting for the installation, after completion, we will find a J-Link Silicon Labs device on the Device column on the interface. Let's click on the device shown above, and the example presentation code selection bar appears on the IDE.
In the Software Examples column, select EFM8SB1 Blinky, quickly turn on a LED flashing program, prompt and load items to IDE.
After we compile the program, after compiling and generate success, we download to the development board. With the demo program, it can be observed that the LED has begun to flash.
summary
Through this evaluation, Silicon Labs has made a lot of effort in the development kit, the development board hardware work and design is very good, integrated development environment Simplicity Studio is more convenient and fast, software Demo is also very humanized. EFM8 uses small packages, combined with innovative low-power technology, from energy saving mode, short-wakeing time, is ideal for all battery-driven applications, EFM8 product lines can be used for touchpad / keyboard, dashboard, wearable products, battery-driven consumption Electronics are the best choice for embedded applications.
