Library Description
The library covers all the necessary functions to control DAC 7 click board. Library performs a standard SPI interface communication.
Key functions:
DAC7_RETVAL_T dac7_set_ch_voltage ( uint8_t addr_ch, uint16_t vol_val, uint16_t v_ref_mv )
- Set the voltage values of the specified channel function.DAC7_RETVAL_T dac7_set_power ( uint8_t pwr_en, uint8_t sel_ch )
- Set power mode function.DAC7_RETVAL_T dac7_sw_reset ( void )
- Software reset function.Examples description
The application is composed of three sections :
void application_task ( )
{
if ( dac7_set_ch_voltage ( DAC7_CHANNEL_A, 1000, v_ref_sel ) == DAC7_SUCCESS )
{
mikrobus_logWrite( " Channel A : 1000 mV ", _LOG_LINE );
}
else
{
mikrobus_logWrite( " ERROR ", _LOG_LINE );
for ( ; ; );
}
Delay_ms( 5000 );
mikrobus_logWrite( "-----------------------", _LOG_LINE );
if ( dac7_set_ch_voltage ( DAC7_CHANNEL_B, 2000, v_ref_sel ) == DAC7_SUCCESS )
{
mikrobus_logWrite( " Channel B : 2000 mV ", _LOG_LINE );
}
else
{
mikrobus_logWrite( " ERROR ", _LOG_LINE );
for ( ; ; );
}
Delay_ms( 5000 );
mikrobus_logWrite( "-----------------------", _LOG_LINE );
if ( dac7_set_ch_voltage ( DAC7_CHANNEL_C, 3000, v_ref_sel ) == DAC7_SUCCESS )
{
mikrobus_logWrite( " Channel C : 3000 mV ", _LOG_LINE );
}

}
else
{

Additional notes and informations
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.
