Library Description

The library covers all the necessary functions to control MUX 3 click board.

Key functions:

• void mux3_setChannel( uint8_t selectChannel ) - Set active MUX channel function.

Examples description

The application is composed of three sections :

• System Initialization - Initializes GPIO and LOG structures, sets AN, RST, CS and PWM pins as output and start to write log.
• Application Initialization - Initialization driver enable's - GPIO, also write log.
• Application Task - (code snippet) This is an example which demonstrates the use of MUX 3 Click board. Sets the current active and changes the channel every 1 sec. Results are being sent to the Usart Terminal where you can track their changes. All data logs write on Usart Terminal changes for every 1 sec.

void applicationTask()
{
    mikrobus_logWrite( "-------------------", _LOG_LINE );
    mikrobus_logWrite( "  Enable Channel:  ", _LOG_LINE );

    _displayLog( _MUX3_ENABLE_CHANNEL_S1 );
    mux3_setChannel( _MUX3_ENABLE_CHANNEL_S1 );
    Delay_1sec();

    _displayLog( _MUX3_ENABLE_CHANNEL_S2 );
    mux3_setChannel( _MUX3_ENABLE_CHANNEL_S2 );
    Delay_1sec();

    _displayLog( _MUX3_ENABLE_CHANNEL_S3 );
    mux3_setChannel( _MUX3_ENABLE_CHANNEL_S3 );
    Delay_1sec();

    _displayLog( _MUX3_ENABLE_CHANNEL_S4 );
    mux3_setChannel( _MUX3_ENABLE_CHANNEL_S4 );
    Delay_1sec();

   _displayLog( _MUX3_ENABLE_CHANNEL_S5 );
    mux3_setChannel( _MUX3_ENABLE_CHANNEL_S5 );
    Delay_1sec();

    _displayLog( _MUX3_ENABLE_CHANNEL_S6 );
    mux3_setChannel( _MUX3_ENABLE_CHANNEL_S6 );
    Delay_1sec();

    _displayLog( _MUX3_ENABLE_CHANNEL_S7 );
    mux3_setChannel( _MUX3_ENABLE_CHANNEL_S7 );
    Delay_1sec();

    _displayLog( _MUX3_ENABLE_CHANNEL_S8 );
    mux3_setChannel( _MUX3_ENABLE_CHANNEL_S8 );
    Delay_1sec();
    
    mikrobus_logWrite( "-------------------", _LOG_LINE );
    mikrobus_logWrite( "      Disable      ", _LOG_LINE );
    mikrobus_logWrite( "    All Channels   ", _LOG_LINE );
    mux3_setChannel( _MUX3_DISABLE_ALL_CHANNELS );
    Delay_1sec();
}

Additional Functions :

• void _displayLog( uint8_t selCh )Display logs on Usart Terminal.

Other mikroE Libraries used in the example:

• GPIO
• 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.
