Library Description

This library carries all necessary functions for controlling Buck 2 click.

Key functions

void buck2_setMode(uint8_t mode) - Sets up working mode

void buck2_setVOUT_3300mV() - Sets up output voltage to 3.3 V

void buck2_setVOUT_2500mV() - Sets up output voltage to 2.5 V

void buck2_setVOUT_1800mV() - Sets up output voltage to 1.8 V

void buck2_setVOUT_1500mV() - Sets up output voltage to 1.5 V

Examples Description

The demo application is composed of three sections:

• System Initialization - Initializes CS pin, RST pin, PWM pin, AN pin as OUTPUT and INT pin as INPUT.
• Application Initialization - Initializes Driver init and settings chip mode as ACTIVE.
• Application Task - (code snippet) - Sets a different range of input voltages every 3 seconds and checks if it has reached the set output voltage.

void applicationTask()
{
     PG_State = buck2_getPowerGood();
     if ( PG_State != 0 )
     {
          mikrobus_logWrite("Power good output voltage", _LOG_LINE);
     }
     buck2_setVOUT_3300mV();
     Delay_ms( 3000 );
     buck2_setVOUT_2500mV();
     Delay_ms( 3000 );
     buck2_setVOUT_1800mV();
     Delay_ms( 3000 );
     buck2_setVOUT_1500mV();
     Delay_ms( 3000 );
}

Other MikroElektronika libraries used in the example:

• 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.
