Power MUX Click

Power MUX Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Click Library

• Author : Mikroe Team
• Date : Sep 2021.
• Type : GPIO type

Software Support

Example Description

This Click features power multiplexer that enables transition between two power supplies, each operating at 2.8V to 5.5V and delivering up to 2A current depending on the package.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.PowerMUX

Example Key Functions

• powermux_cfg_setup Config Object Initialization function.

void powermux_cfg_setup ( powermux_cfg_t *cfg );

• powermux_init Initialization function.

err_t powermux_init ( powermux_t *ctx, powermux_cfg_t *cfg );

• powermux_default_cfg Click Default Configuration function.

void powermux_default_cfg ( powermux_t *ctx );

• powermux_int_pin_read Power MUX pin reading function.

uint8_t powermux_int_pin_read ( powermux_t *ctx );

• powermux_set_mode Power MUX mode set function.

void powermux_set_mode ( powermux_t *ctx, uint8_t mode );

Application Init

Enables GPIO and starts write log.

void application_init ( void ) 
{
    log_cfg_t log_cfg;
    powermux_cfg_t powermux_cfg;

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );

    // Click initialization.
    powermux_cfg_setup( &powermux_cfg );
    POWERMUX_MAP_MIKROBUS( powermux_cfg, MIKROBUS_1 );
    if ( DIGITAL_OUT_UNSUPPORTED_PIN == powermux_init( &powermux, &powermux_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    powermux_default_cfg ( &powermux );
    
    log_info( &logger, " Application Task " );
}

Application Task

Changes power inputs every 3 seconds and displays the currently set mode on the USB UART.

void application_task ( void ) 
{
    log_printf( &logger, " OUTPUT : IN1\r\n\n" );
    powermux_set_mode( &powermux, POWERMUX_INPUT_CHANNEL_1_ON );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    log_printf( &logger, " OUTPUT : IN2\r\n\n" );
    powermux_set_mode( &powermux, POWERMUX_INPUT_CHANNEL_2_ON );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    log_printf( &logger, " OUTPUT : OFF\r\n\n" );
    powermux_set_mode( &powermux, POWERMUX_INPUT_CHANNEL_OFF );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    log_printf( &logger, " OUTPUT : AUTO\r\n\n" );
    powermux_set_mode( &powermux, POWERMUX_INPUT_CHANNEL_AUTO );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
