How to develop safer intelligent devices? (There is an easter egg at the end of the article)
If 2018 is the first year of the Internet of Things, then 2019 will be the year when the Internet of Things accelerates its popularity. In 2019, about 3.6 billion devices will be actively connected to the Internet of Things. With the launch of 5G, more IoT devices will be connected. According to IDC data, by 2021, the number of IoT nodes will exceed 36 billion!
A large number of IoT connections will enable us to achieve truly smart life: smart mirrors will analyze your face and automatically contact a doctor if any symptoms are found. If the user is in a bad mood, it will adjust through music or other content. Smart beds will automatically analyze various user data, and smart forks will detect the nutritional content of food.
However, while being smart and convenient, the security of IoT devices is becoming increasingly prominent. If hackers get into your IoT devices, it means that your life may be taken over by others. Therefore, users need safe and reliable IoT smart devices. How to develop more secure smart devices? Here is an embedded IoT development tool - Microchip's CEC1x02 development board.
The CEC1x02 development board is a platform for developing, demonstrating and testing various IoT applications. The platform is based on a 32-bit ARM® Cortex®-M4 MCU and has secure peripherals. The board has a variety of hardware options (including power, user interface, serial communication, expansion headers, etc.), which can realize rapid prototyping and development of embedded secure IoT.
The CEC1x02 development board features Serial Quad I/O (SQI) Flash, a compact, high contrast, serial graphic LCD display module with backlight, and OTP programmability in the CEC1702. The DM990013 development board includes the baseboard and a CEC1702 PIM with two MikroElektronika Click board™ compatible headers.
Features:
● Connector for CEC1x02 series plug-in modules (PIM)
● The board is powered by the CEC1702 32-bit ARM® Cortex®-M4 MCU with an integrated cryptographic accelerometer (CEC1702PIM).
● Compact, high contrast, serial graphic LCD display module with backlight
● Serial Quad I/O (SQI) Flash
● OTP programmability in CEC1702
Please note that the CEC1x02 development board has two expansion headers compatible with the MikroElektronika MikroBUS™ expansion interface , where the MikroElektronika MikroBUS™ Adapter click boards™ are designed to improve the way users add new features to development boards. Users can insert the Click board into the innovative new MikroBUS™ standard slot and use it without any hardware configuration. The categories of MikroElektronika MikroBUS™ adapter click boards include wireless communication modules, wired communication modules, sensor modules, and other modules and accessories.
The detailed layout of the development board is as follows:
USB micro-B Connector - Powers the board and provides an interface for serial input/output or I2C using the Microchip MCP2221A USB-to-UART/I2C serial converter.
Power Adapter Plug - Provides another way to power the board via a 6 V to 16 V external power adapter, such as the AC002014 - 9 V Wall Power Supply.
Plug-in Module (PIM) Connector - Initially the board is supported by the CEC1702 PIM.
SST26VF016B (on CEC1702 PIM), SQI flash memory used to store the program image for the CEC1702 and provide additional persistent storage for application information.
JTAG Debugger/SPI Flash Programming Header (on CEC1702 PIM) - Shared header design for SWD mode JTAG or external SPI Flash connection controlled by VCC_RST pin.
eFuse Programmability - Ability to evaluate, develop and program all aspects of the CEC1702 including keys used for authentication.
10kΩ Potentiometer - Used as an analog signal source for ADC demonstration or user interface purposes.
ADC Expansion Header - Provides expansion headers for variable resistance circuit elements such as thermistors.
Color LED - Full color PWM driven LED;
Status LED indicator;
128x64 pixel LCD is used to display user application text/images.
JTAG debug header
I2C expansion header
4x4 Keyboard Title
GPIO header
6 general purpose buttons
2 mikroBUS interfaces - used to connect various hardware expansion boards to expand the functionality of the platform.
