We provide a library for the MCP16331 click, as well as a demo application (example), developed using MikroElektronika compilers. The demo application can run on all the main MikroElektronika development boards.

Library Description

The library carries a function for controlling the MCP16331 click output alongside with SPI driver initialization function.

Key functions

• void mcp16331_setVout(uint16_t millivolt ) - Sets voltage on outputs

Examples Description

The application is composed of three sections:

• System Initialization - Initializes GPIO and SPI peripheral, but also and UART used for information logging.
• Application Initialization - Driver initialization.
• Application Task - (code snippet) Periodically changes the output voltage in the range from 5V to 12V. Information about the current output voltage is logged on UART.

void applicationTask()
{
    mcp16331_setVout( 5000 );
    UART1( "rnOutput Voltage changed to 5V" );
    Delay_ms( 3000 );
    mcp16331_setVout( 12000 );
    UART1( "rnOutput Voltage changed to 12V" );
    Delay_ms( 3000 );
}

The example also carries additional functions for GPIO control which are provided during driver initialization. These functions are necessary and implementation depends on development system used.

Other MikroE Libraries used in the example:

• UART

Note

Depending on the development board you are using, you may need the RS232 click or USB-UART click or USB UART 2 click, to connect to your PC. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
