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

Software Support

We provide a library for the Stspin233 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 Stspin233 Click driver.

Standard key functions :

• Config Object Initialization function.

  void stspin233_cfg_setup ( stspin233_cfg_t *cfg );

• Initialization function.

  STSPIN233_RETVAL stspin233_init ( stspin233_t ctx, stspin233_cfg_t cfg );

Example key functions :

• Send single command

  void stspin233_send_single_cmd ( stspin233_t ctx, uint8_t tx_buf );

• Send double command

  void stspin233_send_double_cmd ( stspin233_t ctx, uint8_t cmd_buf, uint8_t *arg_buf );

• Get INT pin state

  uint8_t stspin233_get_int_state ( stspin233_t *ctx );

Examples Description

This application is motor driver.

The demo application is composed of two sections :

Application Init

Initializes driver and configures the Click board.

void application_init ( void )
{
    log_cfg_t log_cfg;
    stspin233_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.

    stspin233_cfg_setup( &cfg );
    STSPIN233_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    stspin233_init( &stspin233, &cfg );

    stspin233_default_cfg( &stspin233 );
}

Application Task

This example demonstrates the use of STSPIN233 Click board, by running the motor clockwise and counter clockwise. All results will be displayed on USB UART.

void application_task ( void )
{
    log_printf( &logger, ">>> START MOTOR\r\n" );
    stspin233_send_single_cmd( &stspin233, STSPIN233_CMD_START_MOTOR );
    stspin233_process( );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    log_printf( &logger, ">>> Set clockwise direction\r\n" );
    stspin233_send_double_cmd( &stspin233, STSPIN233_CMD_DIR_MOTOR, STSPIN233_CW_DIR );
    stspin233_process( );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    log_printf( &logger, ">>> Set counter clockwise direction\r\n" );
    stspin233_send_double_cmd( &stspin233, STSPIN233_CMD_DIR_MOTOR, STSPIN233_CCW_DIR );
    stspin233_process( );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    log_printf( &logger, ">>> STOP MOTOR\r\n" );
    stspin233_send_single_cmd( &stspin233, STSPIN233_CMD_STOP_MOTOR );
    stspin233_process( );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    stspin233_send_single_cmd( &stspin233, STSPIN233_CMD_STATUS );
    stspin233_process( );
    log_printf( &logger, ">>> STATUS: %.5s\r\n", &current_parser_buf[ 9 ] );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    log_printf( &logger, "------------------------------\r\n" );
} 

Note

For all other commands that you can use to control your engine, see the firmware documentation. We used an 8 pole motor for the test.

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.Stspin233

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.
