Library Description

The library covers all the necessary functions to control TMR mix-sens click board.

Key functions:

• uint8_t tmrmixsens_get_omnipolar ( void ) - Get state of the omnipolar ( OMN ) pin function.
• uint8_t tmrmixsens_get_bipolar ( void ) - Get state of the bipolar ( BI ) pin function.

Examples description

The application is composed of three sections :

• System Initialization - Initializes GPIO, sets RTS and CS pins as input and start to write log.
• Application Initialization - Initialization driver enables - GPIO, initializes ADC and set ADC channel.
• Application Task - (code snippet) This is a example which demonstrates the use of TMR mix-sens Click board. This examples respond to changes north or south magnetic pole and display ADC data value. Results are being sent to the Usart Terminal where you can track their changes. All data logs on usb uart for aproximetly every 1 sec.

void application_task ( )
{
    adc_value = tmrmixsens_adc_read( );

    if ( tmrmixsens_get_bipolar( ) == TMRMIXSENS_NORT_POLE )
    {
        mikrobus_logWrite( " ~~~ Nort  pole ~~~ ", _LOG_LINE );
    }
    else
    {
        mikrobus_logWrite( " ~~~ South pole ~~~ ", _LOG_LINE );
    }

    WordToHex( adc_value, demo_text );
    mikrobus_logWrite( " ADC value : 0x", _LOG_TEXT );
    mikrobus_logWrite( demo_text, _LOG_LINE );
    mikrobus_logWrite( "--------------------", _LOG_LINE );
    Delay_ms( 1000 );
}

Other mikroE Libraries used in the example:

• ADC
• UART
• Conversions

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.
