Library Description

The library covers all the necessary functions to control Boost Click board.
Boost click communicates with the target board via SPI protocol. 
This library contains drivers for writing DAC value to the MCP4921 chip and reading ADC value from MCP3551 chip,
set configuration, function for setting desired voltage on output  and function to  getting output voltage.

Key functions:

• void boost_setConfiguration( uint8_t pwrSrc ) - Set configuration function.
• float boost_getVoltage()- Get output voltage function.
• void boost_setVoltage( uint16_t value ) - Set desired voltage on output function.

Examples description

The application is composed of three sections :

- System Initialization - Initializes GPIO, SPI and LOG structures,
     sets AN, CS and RST pins as output.
- Application Initialization - Initialization driver enable's - SPI,
     set configuration and start write log.
- Application Task - (code snippet) This is a example which demonstrates the use of Boost Click board.
     Boost Click communicates with register via SPI by read from MCP3551 chip and write DAC value to the MCP4921 chip.
     This example periodicaly increases and decreases voltage in range between 15 and 30 Volts.
     All data logs write on usb uart for aproximetly every 5 sec.

void applicationTask()
{
    mikrobus_logWrite( " Setting voltage to 15000 mV, _LOG_LINE );
    mikrobus_logWrite( "-----------------------------", _LOG_LINE ); 
    
    boost_setVoltage( 15000 );
    Delay_ms( 5000 );
    
    mikrobus_logWrite( " Setting voltage to 30000 mV", _LOG_LINE );
    mikrobus_logWrite( "-----------------------------", _LOG_LINE );

    boost_setVoltage( 30000 ); 
    Delay_ms( 5000 );
}

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.
