Library Description

The library covers all the necessary functions to control POWER MUX click board. POWER MUX click communicates with the target board through the RST, PWM and INT line. This library offers functions for setting D0 and D1 pins or to use predefined output from input channel 1, output from input channel 2, automatic output channel selection and disable output settings.

Key functions:

  • void powermux_output_input_ch_1 ( ); - Function is used to set output from input channel 1.
  • void powermux_output_input_ch_2 ( ); - Function is used to set output from input channel 2.
  • void powermux_auto_sel_input_ch ( ); - Function is used to set automatic output channel selection.

Examples description

The application is composed of three sections :

  • System Initialization - Initializes GPIO and LOG structures, sets RST and PWM pins as input as output and INT pin as input.
  • Application Initialization - Enables GPIO and starts write log.
  • Application Task - (code snippet) This example demonstrates the use of POWER MUX click board by disabling output tor 2 seconds, then enabling output from channel 1 for 5 seconds then disabling output for 2 seconds again, and repeating for output from channel 2.
void application_task ( )
{
    mikrobus_logWrite( "No output", _LOG_LINE );
    powermux_no_output( );
    Delay_ms( 2000 );
    mikrobus_logWrite( "Output from input channel 1", _LOG_LINE );
    powermux_output_input_ch_1( );
    Delay_ms( 5000 );
    mikrobus_logWrite( "No output", _LOG_LINE );
    powermux_no_output( );
    Delay_ms( 2000 );
    mikrobus_logWrite( "Output from input channel 2", _LOG_LINE );
    powermux_output_input_ch_2( );
    Delay_ms( 5000 );
    mikrobus_logWrite( "No output", _LOG_LINE );
    powermux_no_output( );
    Delay_ms( 2000 );
    mikrobus_logWrite( "auto select output channel", _LOG_LINE );
    powermux_auto_sel_input_ch( );
    Delay_ms( 5000 );
}

Additional notes and informations

Depending on the development board you are using, you may need USB UART clickUSB 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.
