Click library

  • Author : MikroE Team
  • Date : Jul 2020.
  • Type : I2C type

Software Support

We provide a library for the Sram2 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 Sram2 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void sram2_cfg_setup ( sram2_cfg_t *cfg );

  • Initialization function.

    SRAM2_RETVAL sram2_init ( sram2_t ctx, sram2_cfg_t cfg );

Example key functions :

  • Generic write function.

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

  • Generic read function.

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

  • Set PWM pin for write protection.

    void sram2_write_protect( sram2_t *ctx, uint8_t state );

Examples Description

This demo application writes and reads from memory.

The demo application is composed of two sections :

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 );
}

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.Sram2

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.
