How Does The Audio DAC Click Board™ Work?
The Audio DAC Click Board™ is based on a combination of DIR9001 and PCM5142, a digital audio interface receiver and audio stereo DAC from Texas Instruments, suitable for upgrading your audio equipment. The DIR9001 audio receiver can accept signals up to a 108kHz sampling rate at the highest, 24-bit data word, biphase-encoded signal, and complies with the jitter specification IEC60958-3, JEITA CPR1205 (Revised version of EIAJ CP-1201), AES3, and EBUtech3250. These signals are brought to the DIR9001 via an onboard fiber optic S/PDIF connector, better known as Sony/Philips digital interface format, a digital audio interface often used in consumer audio equipment. After receiving the signals, the DIR9001 forwards them for further processing by the stereo audio DAC, the PCM5142, also from Texas Instruments.
The PCM5142 has a fully programmable miniDSP core, allowing developers to integrate filters, dynamic range controls, custom interpolators, and other differentiating features into their applications. It uses the latest generation of TI's advanced segment-DAC architecture to achieve excellent dynamic performance, detailed heights, and an exceptionally good sound stage. Compared with existing DAC technology, the PCM5142 offers up to 20dB lower out-of-band noise, reducing EMI and aliasing in downstream amplifiers/ADCs, accept industry-standard audio data formats with 16- to 32-bit data, and sample rates up to 384kHz. After stereo DAC processing, the output audio signal is available to users for further use on the 3.5mm-line output audio jack, making it suitable for various multimedia systems, satellite radio, CD and DVD players, and more.
The PCM5142 communicates with MCU using the standard I2C 2-Wire data transmission protocol that supports Standard-Mode (100 kHz) and Fast-Mode (400 kHz) operations. In addition to communication pins, this board has several additional functions, providing users with application flexibility. Besides the I2C signals, the mikroBUS™ also has an auto-mute function routed to the MUT pin on the mikroBUS™ socket to mute the device upon intentional or unintentional power loss, as well as one user-configurable general-purpose pin, the IO4 pin of the mikroBUS™ socket. The onboard button labelled as RST can reset the DIR9001 audio receiver.
The Audio DAC Click Board™ can only be operated with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used as a reference for further development.

Software Support
We provide a library for the Audio DAC Click Board™ as well as a demo application (example), developed using MikroE compilers. The demo can run on all the main MikroE development boards.
The package can be downloaded/installed directly from NECTO Studio The package Manager (recommended), downloaded from our LibStock™ or found on MikroE Github account.
Library Description
This library contains API for the Audio DAC Click Board™ driver.
Key functions
-
audiodac_get_gpio4_pinThis function returns the GPIO4 pin logic state. The GPIO4 pin is mapped to auto-mute flag output for both L and R channels by default. -
audiodac_volume_controlThis function sets the volume level for the selected output channel.
Example Description
This example demonstrates the use of the Audio DAC Click Board™ by controlling the volume level of both output channels.
void application_task ( void )
{
static uint8_t volume = AUDIODAC_VOLUME_MUTE;
if ( audiodac_get_gpio4_pin ( &audiodac ) )
{
log_printf ( &logger, " Auto mute flag (both L and R channels are auto muted)rn" );
// Wait until the channels are auto unmuted, i.e. until a valid digital signal is received
while ( audiodac_get_gpio4_pin ( &audiodac ) );
}
if ( AUDIODAC_OK == audiodac_volume_control ( &audiodac, AUDIODAC_CHANNEL_BOTH, volume ) )
{
log_printf ( &logger, "rn Volume: " );
if ( AUDIODAC_VOLUME_MUTE == volume )
{
log_printf ( &logger, "MUTErn" );
Delay_ms ( 3000 );
}
else if ( AUDIODAC_VOLUME_MAX == volume )
{
log_printf ( &logger, "MAXrn" );
Delay_ms ( 3000 );
}
else
{
log_printf ( &logger, "%urn", ( uint16_t ) volume );
Delay_ms ( 100 );
}
volume++;
if ( volume > AUDIODAC_VOLUME_MAX )
{
volume = AUDIODAC_VOLUME_MUTE;
}
}
}
The full application code, and ready to use projects can be installed directly from NECTO Studio The package Manager (recommended), downloaded from our LibStock™ or found on MikroE Github account.
