Library Description

This library allows user to perform a control of the Buck 10 Click board. User can drive the control pin (EN) to turn ON/OFF the device and output voltage. For more details check documentation.

Key functions:

• void buck10_gpioDriverInit(T_BUCK10_P gpioObj) - Convert ADC value to Pressure data in mBar.
• T_BUCK10_RETVAL buck10_enable( T_BUCK10_STATE pwr_state ) - This function allows user to enable or disable the device.

Examples description

The application is composed of three sections :

• System Initialization - Initializes PWM control pin as output and USBUART A port for logging.
• Application Initialization - Initializes GPIO driver.
• Application Task - (code snippet) - Turns ON the Buck 10 for 10 seconds and after that turns OFF the device and output for 10 seconds, and then repeats the all operation. Also when a device state was changed, a message will be sent to the uart terminal. Note: Input voltage recommended range - from 4V to 18V Low-side valley current limit - from 3A to 3.9A Low-side negative current limit - (-2.5A) Output voltage - 3.3V or 5V

void applicationTask()
{
    buck10_enable( _BUCK10_ENABLE );
    mikrobus_logWrite( "** Buck 10 is enabled **", _LOG_LINE );
    Delay_ms( 10000 );
    
    buck10_enable( _BUCK10_DISABLE );
    mikrobus_logWrite( "** Buck 10 is disabled **", _LOG_LINE );
    Delay_ms( 10000 );
}

• UART

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.
