Library Description
The library contains a function for setting a reference output voltage which can be 1030mV, 2046mv, 3070mV or 4096mV.
Key functions:
void digivref_setOutputVoltage( uint8_t Vref ) - Function for set reference output voltageExamples description
The application is composed of the three sections :
void applicationTask()
{
digivref_setOutputVoltage( _DIGIVREF_REF_VOLTAGE_4096mV );
Delay_ms( 3000 );
digivref_setOutputVoltage( _DIGIVREF_REF_VOLTAGE_3070mV );
Delay_ms( 3000 );
digivref_setOutputVoltage( _DIGIVREF_REF_VOLTAGE_2046mV );
Delay_ms( 3000 );
digivref_setOutputVoltage( _DIGIVREF_REF_VOLTAGE_1030mV );
Delay_ms( 3000 );
digivref_setOutputVoltage( _DIGIVREF_REF_VOLTAGE_2046mV );
Delay_ms( 3000 );
digivref_setOutputVoltage( _DIGIVREF_REF_VOLTAGE_3070mV );
Delay_ms( 3000 );
}

SPIAdditional 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.
