Library Description

The library includes function sets the volume for the selected channel, uses two variables or one volume variable. The user has a function for mute/unmute sounds, default settings and function for clears all registers.

Key functions:

  • void equalizer_setVolumeFull(uint8_t channel, int8_t volume) - Set volume for the channel
  • void equalizer_defaultConfiguration() - Default configuration
  • void equalizer_mute(uint8_t mute) - Mute and Unmute

Examples description

The application is composed of the three sections :

  • System Initialization - Initialzes I2C module.
  • Application Initialization - Initialization driver init, default configuration and sets first volume.
  • Application Task - Waits for valid user input and executes functions based on set of valid commands.
  • Commands : '+' - volume up '-' - volume down 'x' - channel up 'z' - channel down 'm' - mute and unmute
void applicationTask()
{
    uint8_t dataReady_;
    char receivedData_;
    
    dataReady_ = UART_Rdy_Ptr( );

    if (dataReady_ != 0)
    {
        receivedData_ = UART_Rd_Ptr( );

        switch (receivedData_)
        {
            case 'z' :
            {
                /* Change channel */
                _channel --;
                if(_channel < 1)
                {
                    _channel = 1;
                }
                _playFlag = 1;
                break;
            }
            case 'x' :
            {
                /* Change channel */
                _channel ++;
                if(_channel > 6)
                {
                    _channel = 6;
                }
                _playFlag = 1;
                break;
            }
            case '+' :
            {
                /* Set volume */
                _volume++;
                if(_volume > 0)
                {
                    _volume = 0;
                }
                _playFlag = 1;
                break;
            }
            case '-' :
            {
                /* Set volume */
                _volume--;
                if(_volume < -79)
                {
                    _volume = -79;
                }
                _playFlag = 1;
                break;
            }
            case 'm' :
            {
                _mute();
                break;
            }
        }
        _play();
    }
}

Additional Functions :

  • void _getCurrentChannel( ) - Return current channel
  • void _play( ) - Start new settings of the channel
  • void _mute( ) - mute and unmute

Other mikroE Libraries used in the example:

  • I2C
  • UART
  • Conversions

Additional notes and informations

Depending on the development board you are using, you may need USB UART clickUSB UART 2 clickor 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.

Matrix G Click

0

Matrix G Click is a mikroBUS add-on board with two green 5x7 matrices driven by two MAX7219 8-bit LED Display Drivers. The active area of each matrix is 7.62mm high and 5.08 mm wide. 7x5 is a standard resolution for displaying ASCII characters, so the Click is essentially a dual-character display capable of showing letters in more readable typefaces compared to a 14-segment display. The Click communicates with the target MCU through the mikroBUS SPI interface with two separate Chip Select lines for each matrix (CSL for the left, CSR for the right). This board is designed to use a 5V power supply.
