Click library

  • Author : MikroE Team
  • Date : Jan 2020.
  • Type : PWM type

Software Support

We provide a library for the Stspin250 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 Stspin250 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void stspin250_cfg_setup ( stspin250_cfg_t *cfg );

  • Initialization function.

    STSPIN250_RETVAL stspin250_init ( stspin250_t *ctx, stspin250_cfg_t *cfg );

  • Click Default Configuration function.

    void stspin250_default_cfg ( stspin250_t *ctx );

Example key functions :

  • This function regulates Direction control pin state. It controls direction
  • of the current.

    void stspin250_set_ph ( stspin250_t *ctx, uint8_t state );

  • This function regulates enable pin state.

    void stspin250_enable ( stspin250_t *ctx, uint8_t state);

  • This function regulates reset pin state.

    void stspin250_reset ( stspin250_t *ctx );

Examples Description

This application enables usage of brushed DC motor driver with the current limiting and current sensing.

The demo application is composed of two sections :

Application Init

Initialization driver init, PWM init and enable device

void application_init ( void )
{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
STSPIN250_MAP_MIKROBUS( cfg, MIKROBUS_1 );
stspin250_init( &stspin250, &cfg );
stspin250_set_duty_cycle ( &stspin250, duty_cycle );
stspin250_pwm_start( &stspin250 );
}

Application Task

Controls the motor speed in both directions and logs all data on UART.

void application_task ( void )
{
clockwise( );
counter_clockwise( );
}

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.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Stspin250

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.
