Buck 20 Click Board

We provide a library for the Buck 20 Click Board™ and 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 Buck 20 Click Board™ driver.

Key functions

• buck20_set_wiper_1 This function sets wiper 1 to the desired value.

• buck20_enable_device This function enables the buck device by setting the RST pin to high logic state.

• buck20_disable_device This function disables the buck device by setting the RST pin to low logic state.

Example Description

This example demonstrates the use of the Buck 20 Click Board™ by changing the output voltage.

void application_task ( void ) 
 { 
     static uint16_t digipot_wiper = BUCK20_WIPER_ZERO_SCALE; 
     float buck_r1_kohm, buck_vout; 
     if ( BUCK20_OK == buck20_set_wiper_1 ( &buck20, digipot_wiper ) ) 
     { 
         buck_r1_kohm = BUCK20_RESISTOR_R6_KOHM +  
                        ( float ) ( BUCK20_DIGIPOT_MAX_KOHM * digipot_wiper ) / BUCK20_WIPER_FULL_SCALE; 
         buck_vout = BUCK20_BUCK_VREF + ( buck_r1_kohm * BUCK20_BUCK_VREF ) / BUCK20_BUCK_R2_KOHM; 
         log_printf( &logger, " Digipot wiper position: %urn", digipot_wiper ); 
         log_printf( &logger, " Approximate R1 (Digipot+R6): %.2f kOhmrn", buck_r1_kohm ); 
         log_printf( &logger, " Approximate buck voltage output: %.2f Vrnn", buck_vout ); 
         digipot_wiper += 50; 
         if ( digipot_wiper > BUCK20_WIPER_FULL_SCALE ) 
         { 
             digipot_wiper = BUCK20_WIPER_ZERO_SCALE; 
         } 
     } 
     Delay_ms ( 3000 ); 
 }

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.

Other MikroE Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.Buck20

Additional Notes and Information

Depending on the development board you are using, you may need USB UART Click Board™, 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. UART terminal is available in all MikroE compilers.

MIKROSDK

The Buck 20 Click Board™ is supported with mikroSDK - MikroE Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
