Library Description

Library contains functions for STSPIN233 click initialization and basic control. User has at it's disposal this library, which contains functions for waking up the module and sending commands to it. Click board can also be initialized and used with UART terminal.

Key functions:

• void stspin233_send_single_cmd ( uint8_t *tx_buf ) - Send single command
• void stspin233_send_double_cmd ( uint8_t *cmd_buf, uint8_t *arg_buf ) - Send double command
• void stspin233_wakeup( ) - Module wake-up (procedure)

Examples description

The application is composed of three sections :

• System Initialization - Initializes UART module and all necessary GPIO pins.
• Application Initialization - Initializes driver init, starts basic engine setups and initializes a uart interrupt routine for logs data.
• Application Task - Waits for valid user input and executes functions based on set of valid commands.
• Commands : 'S or s' - Start Motor 'B or b' - Brake/Stop motor 'D or d' - Change of motor direction '?' - FW motor status

void application_task ( )
{
    uint8_t console_drdy;
    char console_rx_data;
    
    console_drdy = UART_Rdy_Ptr( );

    if ( console_drdy != 0 )
    {
        console_rx_data = UART_Rd_Ptr( );
        app_cmd_parser( console_rx_data );
    }
}

Additional Functions :

• app_cmd_parser ( ) - Console command parser
• set_interrupt ( ) - Interrupt init and enable
• 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.

Other mikroE Libraries used in the example:

• UART

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.
