Library Description

The library carries a generic command parser adopted for AT command based modules. Generic parser.

Key functions:

• spectral3_cmdSingle - Sends the provided command to the module.
• spectral3_setHandler - Handler assignation to the provided command.
• spectral3_modulePower -  Turns on the module.

Examples Description

The demo application is composed of three sections:

• System Initialization - Initializes all necessary GPIO pins, UART used for the communication with Spectral 3 and UART used for information logging.
• Application Initialization - Initializes the driver, resets the 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 USB-UART, all six values read from Spectral 3 click. The 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();
}

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

mikroE Libraries used in the example:

• UART Library
• Conversions Library
• C_String Library

Additional notes and information

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.
