SRAM 2 Click

SRAM 2 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Example Description

This demo application writes and reads from memory.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Sram2

Example Key Functions

• sram2_cfg_setup Config Object Initialization function.

void sram2_cfg_setup ( sram2_cfg_t *cfg );

• sram2_init Initialization function.

err_t sram2_init ( sram2_t *ctx, sram2_cfg_t *cfg );

• sram2_generic_write Generic write function.

void sram2_generic_write ( sram2_t *ctx, uint16_t reg, uint8_t wr_data );

• sram2_generic_read Generic read function.

void sram2_generic_read ( sram2_t *ctx, uint16_t reg, uint8_t rx_data );

• sram2_write_protect Set PWM pin for write protection.

void sram2_write_protect ( sram2_t *ctx, uint8_t state );

Application Init

Initializes driver init.

void application_init ( void )
{
    log_cfg_t log_cfg;
    sram2_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.

    sram2_cfg_setup( &cfg );
    SRAM2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    sram2_init( &sram2, &cfg );
}

Application Task

Writes and then reads data from memory.

void application_task ( void )
{
    uint8_t cnt;
     
    log_printf( &logger, ">> Write data [ MikroE ] to memory. \r\n" );

    sram2_write_protect( &sram2, SRAM2_WR_ENABLE );
    for ( cnt = 0; cnt < 8; cnt++ )
    {
        sram2_generic_write( &sram2, memory_addr + cnt, message_data[ cnt ] );
    }
    Delay_ms ( 1000 );
    sram2_write_protect( &sram2, SRAM2_WR_DISABLE );

    log_printf( &logger, ">> Read data from memory. Data : " );
    for ( cnt = 0; cnt < 8; cnt++ )
    {
        sram2_generic_read( &sram2, memory_addr + cnt, rx_data );
        log_printf( &logger, " %c ", rx_data );
        Delay_100ms( );
    }
    log_printf( &logger, "  \r\n" );
    log_printf( &logger, "-------------------------------- \r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
