Library Description

The library covers all the necessary functions that enables the usage of the ADAC click board.
It initializes and defines the I2C driver and drivers that offer a choice for reading and writing DAC
data from and to all eight channels and reading ADC data from all eight channels. User also has diferent 
functions that allow diferent settings at his disposal.

Key functions:

• void adac_setConfiguration( uint8_t ptByte, uint8_t msbData, uint8_t lsbData ) - Function is used to configure the device to users needs.
• void adac_writeDACData( uint8_t wrChann, uint16_t wrData ) - Function is used to write 16-bit data to the designated channel.
• uint16_t adac_readADC( uint8_t *IOChannel ) - Function is used to read ADC value from any of the channels.

Examples description

The application is composed of three sections :

• System Initialization - Initializes GPIO, I2C and LOG structures, set RST pin as output.
• Application Initialization - Initalizes I2C driver, sets up default configuration and makes an initial log.
• Application Task - This is an example that shows some of the functions that ADAC click has. It demonstrates Write DAC and read ADC functions and settings.

void applicationTask()
{
    uint16_t i;
    uint16_t ADCValue;
    uint8_t channel;
    char logTxt[ 50 ];

mikrobus_logWrite( " Write DAC demonstration  ", _LOG_LINE );
    adac_setConfiguration( _ADAC_DAC_CONFIG, _ADAC_NO_OP, _ADAC_IO3 );
    Delay_ms( 100 );
    for ( i = 0; i < 0XFF; i += 4 )
    {
        adac_writeDAC( _ADAC_PB_PIN3, i / 0x100, i % 0x100 );
        Delay_ms( 10 );
        mikrobus_logWrite( " * ", _LOG_LINE );

            }
    mikrobus_logWrite( " Demonstration finished  ", _LOG_LINE );
    mikrobus_logWrite( "-------------------------", _LOG_LINE );
    Delay_ms( 1000 );
        mikrobus_logWrite( " Read ADC demonstration  ", _LOG_LINE );
    adac_setConfiguration( _ADAC_ADC_CONFIG, _ADAC_NO_OP, _ADAC_IO4 );
    Delay_ms( 100 );
    adac_setConfiguration( _ADAC_ADC_SEQUENCE, _ADAC_SEQUENCE_ON, _ADAC_IO4 );
    for ( i = 0; i < 10; i++ )
    {
        ADCValue = adac_readADC( &channel );
        ShortToStr( channel, logTxt );
        Ltrim( logTxt );
        mikrobus_logWrite( "ADC value on channel ", _LOG_TEXT );
        mikrobus_logWrite( logTxt, _LOG_TEXT );
        mikrobus_logWrite( " is : ", _LOG_TEXT );
        WordToStr( ADCValue, logTxt );
        Ltrim( logTxt );
        mikrobus_logWrite( logTxt, _LOG_LINE );
        Delay_ms( 2000 );
    }
    mikrobus_logWrite( " Demonstration finished  ", _LOG_LINE );
    mikrobus_logWrite( "-------------------------", _LOG_LINE );
    Delay_ms( 1000 );
}

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.
