Library Description
The library initializes and defines the I2C bus driver and drivers that offer a choice for writing data in registers and reading data from registers. The library includes functions for set output voltage, enable and disable buck, configuration buck and read buck status.
Key functions:
void c3xbuck_enableBuck(uint8_t buck) - Function for enable Buckvoid c3xbuck_setVoltage(uint8_t buck, uint8_t voltage) - Function for set output voltagevoid c3xbuck_configurationBuck(uint8_t buck, uint8_t config) - Function for configuration buckExamples description
The application is composed of the three sections :
void applicationTask()
{
c3xbuck_setVoltage(_C3XBUCK_SELECT_BUCK_1, _C3XBUCK_OUTPUT_VOLTAGE_1000mV);
c3xbuck_setVoltage(_C3XBUCK_SELECT_BUCK_2, _C3XBUCK_OUTPUT_VOLTAGE_1250mV);
c3xbuck_setVoltage(_C3XBUCK_SELECT_BUCK_3, _C3XBUCK_OUTPUT_VOLTAGE_1500mV);
Delay_ms( 5000 );
c3xbuck_setVoltage(_C3XBUCK_SELECT_BUCK_1, _C3XBUCK_BUCK_DEFAULT_OUTPUT_VOLTAGE);
c3xbuck_setVoltage(_C3XBUCK_SELECT_BUCK_2, _C3XBUCK_BUCK_DEFAULT_OUTPUT_VOLTAGE);
c3xbuck_setVoltage(_C3XBUCK_SELECT_BUCK_3, _C3XBUCK_BUCK_DEFAULT_OUTPUT_VOLTAGE);
Delay_ms( 5000 );
}

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.
