Library Description
This library performs a control of the Buck 13 click board, which is used to convert the input DC voltage, in the range from 6.5V to 50V, to output DC voltage of 3.3V, with maximal current of 3A. Library uses SPI serial interface to allow the ADC output reading from the Buck 13. For more details check documentation.
Key functions:
void buck13_spiDriverInit( T_BUCK13_P gpioObj, T_BUCK13_P spiObj )
- This function initializes SPI serial interface.void buck13_enable( T_BUCK13_STATE pwr_state )
- This function allows user to perform a control of the Buck 13 output.uint16_t buck13_getVoltage( void )
- This function returns the output voltage value calculated to millivolts.Examples description
The application is composed of three sections :
void applicationTask()
{
rx_dat = UART_Rdy_Ptr();
if (rx_dat != 0)
{
rx_dat = UART_Rd_Ptr();
switch (rx_dat)
{
case 'e' :
{
if (out_state == _BUCK13_DISABLE)
{
buck13_enable( _BUCK13_ENABLE );
out_state = _BUCK13_ENABLE;
mikrobus_logWrite( "** Buck 13 output is enabled now.", _LOG_LINE );
}
else
{
mikrobus_logWrite( "** Buck 13 output is already enabled.", _LOG_LINE );
}
break;
}
case 'd' :
{
if (out_state == _BUCK13_ENABLE)
{
buck13_enable( _BUCK13_DISABLE );
out_state = _BUCK13_DISABLE;
mikrobus_logWrite( "** Buck 13 output is disabled now.", _LOG_LINE );
}
else
{
mikrobus_logWrite( "** Buck 13 output is already disabled.", _LOG_LINE );
}
break;
}
case 'v' :
{
out_voltage = buck13_getVoltage();
WordToStr( out_voltage, text );
Ltrim( text );
mikrobus_logWrite( "** VOUT = ", _LOG_TEXT );
mikrobus_logWrite( text, _LOG_TEXT );
mikrobus_logWrite( " mV.", _LOG_LINE );
break;
}
case 'c' :
{
writeCmd();
break;
}
default :
{
mikrobus_logWrite( "***** Invalid command. *****", _LOG_LINE );
writeCmd();

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.
