Library Description

Initializes and defines SPI driver and driver functions which can use for power supply control. This library offers a choice to set maximum output voltage, which can be between 1V and 5.5V. For more details check the documentation.

Key functions :

void buck5_powerOn() - Function for power ON chip.
void buck5_reset() - Function for reset chip.
void buck5_setOutputVoltage(uint8_t voltage) - Function for setting maximum output voltage.
 

Example description

The application is composed of three sections :

• System Initialization - Initializes SPI module and AN pin, RST pin, CS pin as OUTPUT and PWM pin as INPUT.
• Application Initialization - Initializes driver init, power On-chip and reset Buck 5 click.
• Application Task - (code snippet) - Sets 3 different output voltage every 2 seconds.

void applicationTask()
{
 buck5_setOutputVoltage(BUCK5_VOLTAGE_1500mV);
 Delay_ms( 2000 );
 buck5_setOutputVoltage(BUCK5_VOLTAGE_3000mV);
 Delay_ms( 2000 );
 buck5_setOutputVoltage(BUCK5_VOLTAGE_4500mV);
 Delay_ms( 2000 );
 buck5_setOutputVoltage(BUCK5_VOLTAGE_3000mV);
 Delay_ms( 2000 );
}

Other mikroE Libraries used in the example:

• Conversions
• 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.
