Hardware Overview

How does it work?

Thermo 20 Click is based on the TSYS03, an ultra-compact digital temperature sensor with precise digital output and low power consumption from TE Connectivity. The TSYS03 is factory-calibrated and provides accurate temperature measurements through several I2C configurable addresses. Operating from a supply voltage between 2.4V and 5.5V and drawing just 5µA Thermo 20 Click board™ is well suited for battery-powered and automotive applications. With an extended operating range from -40°C to +125°C, the TSYS03 provides digital temperature measurements that offer an accuracy of ±0.5°C when operating at ambient temperatures between 0°C and 60°C. The TSYS03 consists of a semiconductor

diode as a measuring element, which was integrated into an ASIC. The temperature is obtained from the voltage that drops across the diode and through an A/D converter with a 16-bit resolution. The output is obtained as a digital value via a configurable I2C interface. The TSYS03 impresses with its high accuracy, current consumption lower than 5 µA, and low self-heating of max. 0.1 °C. Thermo 20 Click communicates with MCU using the standard I2C 2-Wire interface with a maximum clock frequency of 1MHz. The standard I2C address is 0x40, but the sensor can also react to a second, alternative I2C address. It is possible to do one-time subsequent writing of an alternative static I2C address.

This leads to a wrong memory CRC, but the sensor is still functional. It is also possible to write an alternative I2C address to the sensor during operation. This address is temporary and is overwritten during a software reset or a hardware restart function. This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used as a reference for further development.

Features overview

Development board

Fusion for TIVA v8 is a development board specially designed for the needs of rapid development of embedded applications. It supports a wide range of microcontrollers, such as different 32-bit ARM® Cortex®-M based MCUs from Texas Instruments, regardless of their number of pins, and a broad set of unique functions, such as the first-ever embedded debugger/programmer over a WiFi network. The development board is well organized and designed so that the end-user has all the necessary elements, such as switches, buttons, indicators, connectors, and others, in one place. Thanks to innovative manufacturing technology, Fusion for TIVA v8 provides a fluid and immersive working experience, allowing access

anywhere and under any circumstances at any time. Each part of the Fusion for TIVA v8 development board contains the components necessary for the most efficient operation of the same board. An advanced integrated CODEGRIP programmer/debugger module offers many valuable programming/debugging options, including support for JTAG, SWD, and SWO Trace (Single Wire Output)), and seamless integration with the Mikroe software environment. Besides, it also includes a clean and regulated power supply module for the development board. It can use a wide range of external power sources, including a battery, an external 12V power supply, and a power source via the USB Type-C (USB-C) connector.

Communication options such as USB-UART, USB HOST/DEVICE, CAN (on the MCU card, if supported), and Ethernet is also included. In addition, it also has the well-established mikroBUS™ standard, a standardized socket for the MCU card (SiBRAIN standard), and two display options for the TFT board line of products and character-based LCD. Fusion for TIVA v8 is an integral part of the Mikroe ecosystem for rapid development. Natively supported by Mikroe software tools, it covers many aspects of prototyping and development thanks to a considerable number of different Click boards™ (over a thousand boards), the number of which is growing every day.

 * @brief Thermo20 Click example
 *
 * # Description
 * This example showcases the ability of Thermo 20 Click board to
 * read it's serial number. It can read themperature and measure from -40degC to
 * 120degC.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization communication modules(I2C, UART). Resets device and read Serial Number.
 *
 * ## Application Task
 * In span of ~ 1000ms it sends command for adc conversion of temperature, reads ADC value,
 * and calculates temperature in degrees C.
 * 
 * @note For this driver to work on 18bit PIC MCU-s you need to additionally pull up communication lines.
