We provide a library for the Thermo Click on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Library Description
The library covers all the necessary functions to control Thermo Click board. Library performs the communication with the device via SPI driver by reading data from MAX31855 sensor. Library have function for measuring thermocouple temperature and convert to degree Celsius and function for checking the error: short-circuited to Vcc, short-circuited to GND or no connections.
Key functions :
float thermo_getTemperature()- Get thermocouple temperature function.uint8_t thermo_checkFault()- Check fault states function.uint32_t thermo_readData()- Read all data from sensor function.
Examples Description
The application is composed of three sections :
- System Initialization - Initializes GPIO, SPI and LOG structures, sets CS pins as output.
- Application Initialization - Initialization driver enable's - SPI start write log.
- Application Task - (code snippet) This is a example which demonstrates the use of Thermo Click board. Temperature measured by the thermocouple is converter by MAX31855 sensor on Thermo click board. Displayed temperature is in degree Celsius. Results are being sent to the Usart Terminal where you can track their changes. All data logs write on usb uart changes for every 3 sec.
void applicationTask()
{
temperature = thermo_getTemperature();
FloatToStr( temperature, logText );
mikrobus_logWrite( " Temperature : ", _LOG_TEXT );
mikrobus_logWrite( logText, _LOG_TEXT );
mikrobus_logWrite( degCel, _LOG_LINE );
mikrobus_logWrite( "------------------------", _LOG_LINE );
Delay_ms( 3000 );
}Additional Functions :
void displayErrorMsg()- Check and displayed error messages.
The full application code, and ready to use projects can be found on our LibStock page.
Other mikroE Libraries used in the example:
- SPI
- UART
- Conversion
Additional notes and informations
Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
