MCP16331 click functions as a buck-boost voltage regulator, a switching regulator topology that combines principles of the buck conversion (step-down) and the boost conversion (step-up).
- Author : MikroE Team
- Date : Jan 2020.
- Type : SPI type
We provide a library for the Mcp16331 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 Mcp16331 Click driver.
- Config Object Initialization function.
void mcp16331_cfg_setup ( mcp16331_cfg_t *cfg );
- Initialization function.
MCP16331_RETVAL mcp16331_init ( mcp16331_t *ctx, mcp16331_cfg_t *cfg );
- mcp16331 set vout
void mcp16331_set_vout ( mcp16331_t *ctx, uint16_t millivolts_vout );
This application is buck-boost voltage regulator.
The demo application is composed of two sections :
Sends hal pointers, and initializes click
void application_init ( void )
{
log_cfg_t log_cfg;
mcp16331_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.
mcp16331_cfg_setup( &cfg );
MCP16331_MAP_MIKROBUS( cfg, MIKROBUS_1 );
mcp16331_init( &mcp16331, &cfg );
}
Switches between 5 V and 12 V values
void application_task ( void )
{
mcp16331_set_vout( &mcp16331, 5000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
mcp16331_set_vout( &mcp16331, 12000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
}
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.

- MikroSDK.Board
- MikroSDK.Log
- Click.Mcp16331
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.
