• CIC Prefix : SPECTRAL3
• Author : Katarina Perendic
• Verison : 1.0.0
• Date : Feb 2018.

We provide a library for the Spectral3 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

Library carries generic command parser adopted for AT command based modules. Generic parser

Key functions :

• spectral3_cmdSingle - Sends provided command to the module
• spectral3_setHandler - Handler assignation to the provied command
• spectral3_modulePower - Turn on module

Examples Description

The demo application is composed of three sections :

• System Initialization - Initializes all necessary GPIO pins, UART used for the communcation with Spectral 3 and UART used for infromation logging.
• Application Initialization - Initializes driver, reset module and sends commands for auto baudrate, GAIN configuration and Mode configuration.
• Application Task (Code Snippet) - Sends the command to start reading data. Then logs to USBUART, all six values read from Spectral 3 click. Operation is repeated every 1 second.

void applicationTask()
{
    spectral3_process();
    spectral3_cmdSingle(&cmdData[0]);
    spectral3_getData(&rspBuffer[0],&readData[0]);
    
    IntToStr(readData[0],text);
    mikrobus_logWrite( "-- R value:", _LOG_TEXT );
    mikrobus_logWrite( text, _LOG_LINE );

    IntToStr(readData[1],text);
    mikrobus_logWrite( "-- S value:", _LOG_TEXT );
    mikrobus_logWrite( text, _LOG_LINE );

    IntToStr(readData[2],text);
    mikrobus_logWrite( "-- T value:", _LOG_TEXT );
    mikrobus_logWrite( text, _LOG_LINE );

    IntToStr(readData[3],text);
    mikrobus_logWrite( "-- U value:", _LOG_TEXT );
    mikrobus_logWrite( text, _LOG_LINE );

    IntToStr(readData[4],text);
    mikrobus_logWrite( "-- V value:", _LOG_TEXT );
    mikrobus_logWrite( text, _LOG_LINE );

    IntToStr(readData[5],text);
    mikrobus_logWrite( "-- W value:", _LOG_TEXT );
    mikrobus_logWrite( text, _LOG_LINE );

    mikrobus_logWrite( "---------------------", _LOG_LINE );
    Delay_1sec();
}

Alongside with the demo application timer initialization functions are provided. Note that timer is configured acording to default develoment system and MCUs, changing the system or MCU may require update of timer init and timer ISR functions.

The full application code, and ready to use projects can be found on our LibStock page.

Other mikroE Libraries used in the example:

• UART Library
• Conversion Library
• C_String Library

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.
