Library Description

The library covers all the necessary functions to control Step Down 2 click board. User can enable or disable the device and check for fault occurrence.

Key functions:

  • void stepdown2_dev_enable ( uint8_t state ); - Function is used to enable or disable the device.
  • uint8_t stepdown2_check_fault ( ); - Function is used to check whether the the fault has occured.

Examples description

The application is composed of three sections :

  • System Initialization - Initializes LOG structure and sets CS as output and RST as input.
  • Application Initialization - Initializes GPIO driver and starts log.
  • Application Task - (code snippet) This example demonstrates the use of Step Down 2 click by enabling the device, and if the output voltage is good.
void application_task ( )
{
    if ( stepdown2_check_fault( ) )
    {
        mikrobus_logWrite( "Device working properly!", _LOG_LINE );
    }
    else
    {
        mikrobus_logWrite( "Fault detected!", _LOG_LINE );
    }
    Delay_ms( 1000 );
    mikrobus_logWrite( "--------------------", _LOG_LINE );
}

Other mikroE Libraries used in the example:

  • UART

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.
