Click library

Software Support

We provide a library for the Dac7 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Dac7 Click driver.

Examples Description

This is an example that demonstrates the use of the DAC 7 Click board, that converts digital value to the corresponding voltage level using external voltage reference.

The demo application is composed of two sections :

Application Init

Application Init performs Logger and Click initialization.

void application_init ( void )
{
log_cfg_t log_cfg;
// Logger initialization.
log_cfg.level = LOG_LEVEL_DEBUG;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_printf( &logger, "--------------------------\r\n\n" );
log_printf( &logger, " Application Init\r\n" );
Delay_ms ( 100 );
// Click initialization.
dac7_cfg_setup( &cfg );
DAC7_MAP_MIKROBUS( cfg, MIKROBUS_1 );
dac7_init( &dac7, &cfg );
log_printf( &logger, "--------------------------\r\n\n" );
log_printf( &logger, " ------ DAC 7 Click ------\r\n" );
log_printf( &logger, "--------------------------\r\n\n" );
Delay_ms ( 1000 );
if ( dac7_sw_reset( &dac7 ) == DAC7_SUCCESS )
{
log_printf( &logger, " Software reset \r\n" );
}
else
{
log_printf( &logger, " ERROR \r\n" );
for ( ; ; );
}
Delay_ms( 1000 );
log_printf( &logger, "--------------------------\r\n\n" );
{
log_printf( &logger, " All channel Power On \r\n" );
}
else
{
log_printf( &logger, " ERROR \r\n" );
for ( ; ; );
}
Delay_ms( 100 );
log_printf( &logger, "--------------------------\r\n\n" );
log_printf( &logger, " -- Initialization done. --\r\n" );
log_printf( &logger, "--------------------------\r\n\n" );
Delay_ms ( 1000 );
}

Application Task

In this example, we adjust the DAC output voltage from 1000 mV to 4000 mV for the channels, starting from channel A to channel D and set the DAC output voltage to 5000 mV for all channels. Results are being sent to UART Terminal where you can track their changes. All data logs write on USB UART changes every 5 sec.

void application_task ( void )
{
{
log_printf( &logger, " Channel A : 1000 mV \r\n" );
}
else
{
log_printf( &logger, " ERROR \r\n" );
for ( ; ; );
}
Delay_ms( 5000 );
log_printf( &logger, "--------------------------\r\n\n" );
{
log_printf( &logger, " Channel B : 2000 mV \r\n" );
}
else
{
log_printf( &logger, " ERROR \r\n" );
for ( ; ; );
}
Delay_ms( 5000 );
log_printf( &logger, "--------------------------\r\n\n" );
{
log_printf( &logger, " Channel C : 3000 mV \r\n" );
}
else
{
log_printf( &logger, " ERROR \r\n" );
for ( ; ; );
}
Delay_ms( 5000 );
log_printf( &logger, "--------------------------\r\n\n" );
{
log_printf( &logger, " Channel D : 4000 mV \r\n" );
}
else
{
log_printf( &logger, " ERROR \r\n" );
for ( ; ; );
}
Delay_ms( 5000 );
log_printf( &logger, "--------------------------\r\n\n" );
{
log_printf( &logger, " All Channels: 5000 mV \r\n" );
}
else
{
log_printf( &logger, " ERROR \r\n" );
for ( ; ; );
}
Delay_ms( 5000 );
log_printf( &logger, "--------------------------\r\n\n" );
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

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.
