VReg Click is a digitally controlled DC Voltage regulator in mikroBUS™ form factor.
We provide a library for the Vreg 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.
This library contains API for Vreg Click driver.
Config Object Initialization function.
void vreg_cfg_setup ( vreg_cfg_t *cfg );
Initialization function.
VREG_RETVAL vreg_init ( vreg_t ctx, vreg_cfg_t cfg );
Get ADC value function.
uint16_t vreg_get_adc ( vreg_t *ctx, uint8_t channel );
Set output voltage function.
void vreg_set_out_voltage ( vreg_t *ctx, uint16_t value_dac );
Set output voltage procentage function.
void vreg_set_output_voltage_procentage ( vreg_t *ctx, uint8_t value_dac_pct );
This is an example that demonstrates the use of VREG Click board.
The demo application is composed of two sections :
Initializes driver and sets output voltage.
void application_init ( void )
{
log_cfg_t log_cfg;
vreg_cfg_t cfg;
/**
* Logger initialization.
* Default baud rate: 115200
* Default log level: LOG_LEVEL_DEBUG
* @note If USB_UART_RX and USB_UART_TX
* are defined as HAL_PIN_NC, you will
* need to define them manually for log to work.
* See @b LOG_MAP_USB_UART macro definition for detailed explanation.
*/
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
vreg_cfg_setup( &cfg );
VREG_MAP_MIKROBUS( cfg, MIKROBUS_1 );
vreg_init( &vreg, &cfg );
vreg_stop_measuring( &vreg );
log_printf( &logger, " Stop Measuring \r\n" );
Delay_1sec( );
log_printf( &logger, " Set Out Voltage \r\n" );
vreg_set_out_voltage( &vreg, 600 );
Delay_1sec( );
log_printf( &logger, " Start Measuring \r\n" );
vreg_start_measuring( &vreg );
Delay_1sec( );
}
Reads ADC data from all 3 channels, converts those values to voltage and displays the results on USB UART.
void application_task ( void )
{
ch_reg = vreg_get_adc( &vreg, VREG_CHANNEL_0 );
voltage = ch_reg / 182.0;
log_printf( &logger, " CH Reg : %.2f V\r\n", voltage );
Delay_10ms( );
ch_in = vreg_get_adc( &vreg, VREG_CHANNEL_2 );
voltage = ch_in / 182.0;
log_printf( &logger, " CH In : %.2f V\r\n", voltage );
Delay_10ms( );
ch_out = vreg_get_adc( &vreg, VREG_CHANNEL_1 );
voltage = ch_out / 182.0;
log_printf( &logger, " CH Out : %.2f V\r\n", voltage );
Delay_1sec( );
log_printf( &logger, " ---------------------- \r\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.
