Library Description

The library covers all the necessary functions to control Boost 4 Click board.
Boost 4 click communicates with the target board via SPI protocol. 
This library contains drivers for enable the device regulator, forces the device into shutdown mode,
for sets output voltage and for sets min and max output voltage.

Key functions:

• void boost4_enable() - Enable the device regulator function.

• void boost4_setOutVoltage( uint16_t value ) - Set output voltage function.

• void boost4_setOutVoltageMax() - Set the maximum output voltage function.

Examples description

The application is composed of the three sections :

• System Initialization - Initializes GPIO, SPI and LOG structures,
       sets CS and RST pins as output.
• Application Initialization - Initialization driver enable's - SPI,
       enable the device regulator and start write log.
• Application Task - (code snippet) This is a example which demonstrates the use of Boost 4 Click board. Boost 4 Click communicates with register via SPI by write value to the TPS61230A chip. This example shows how to set the desired output voltage, by cycling through a couple of predefined voltage values.
  All data logs write on usb uart for aproximetly every 5 sec.

void applicationTask()
{
    mikrobus_logWrite( " Set the max Vout ~ 5.25 V ", _LOG_LINE );
 
    boost4_setOutVoltageMax();
    Delay_ms( 5000 );

    mikrobus_logWrite( "-----------------------------", _LOG_LINE );
    mikrobus_logWrite( " Set the min Vout ~ 3.05 V ", _LOG_LINE );

    boost4_setOutVoltageMin();
    Delay_ms( 5000 );

    mikrobus_logWrite( "-----------------------------", _LOG_LINE );

}

Other mikroE Libraries used in the example:

• SPI
• UART

Additional notes and information

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.
