EERAM 2 Click is a standalone serial SRAM memory that includes shadow non-volatile backup. EERAM uses a small external capacitor to provide the energy needed to move the contents of the SRAM to the non-volatile cells when system power is lost.

Library Description

The library covers all the necessary functions to control EERAM 2 Click board. A library performs the communication with the 48LM01 1-Mbit SPI Serial EERAM on the EERAM 2 click board.

Key functions:

  • void eeram2_set_write_status ( uint8_t en_write ) - Set write status function.
  • EERAM2_RETVAL_T eeram2_write_continuous ( uint32_t reg, uint8_t *p_tx_data, uint8_t n_bytes ) - Continuous write the data into SRAM function.
  • EERAM2_RETVAL_T eeram2_read_continuous ( uint32_t reg, uint8_t *p_rx_data, uint8_t n_bytes ) - Continuous read the data into SRAM function.

Examples description

The application is composed of three sections :

  • System Initialization - Initializes SPI, sets CS nad PWM pin as outputs and begins to write log.
  • Application Initialization - Initialization driver enables - SPI, disabled SPI communication pause with the device and set write enable instruction.
  • Application Task - (code snippet) This is an example that demonstrates the use of the EERAM 2 Click board. In this example, we write and then read data from SRAM memory. Results are being sent to the Usart Terminal where you can track their changes. All data logs write on USB uart changes approximately for every 1 sec.
void application_task ( )
{
    check_status = eeram2_write_continuous( 0x00543210, &demo_data[ 0 ], 9 );

    if ( check_status == EERAM2_ERROR )
    {
        mikrobus_logWrite( "   ERROR Writing    ", _LOG_LINE );
        mikrobus_logWrite( "--------------------", _LOG_LINE );
        for ( ; ; );
    }

    mikrobus_logWrite( "     Writing...     ", _LOG_LINE );
    mikrobus_logWrite( "--------------------", _LOG_LINE );
    Delay_ms( 100 );

    check_status = eeram2_read_continuous( 0x00543210, &read_data[ 0 ], 9 );

    if ( check_status == EERAM2_ERROR )
    {
        mikrobus_logWrite( "   Reading ERROR    ", _LOG_LINE );
        mikrobus_logWrite( "--------------------", _LOG_LINE );
        for ( ; ; );
    }

    mikrobus_logWrite( " Read data : ", _LOG_TEXT );

    for ( cnt = 0; cnt < 9; cnt++ )
    {
        mikrobus_logWrite( &read_data[ cnt ], _LOG_BYTE );
    }

    mikrobus_logWrite( "--------------------", _LOG_LINE );
    Delay_ms( 1000 );
}

Other mikroE Libraries used in the example:

  • SPI
  • UART
  • Conversions

Additional notes and informations

Depending on the development board you are using, you may need USB UART clickUSB 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.

LED Ring 2 Click

0

LED Ring 2 Click is a compact add-on board that provides a circular-shaped electronic lighting solution. This board features three I2C-configurable high-performance LED matrix drivers, the LP5862 from Texas Instruments. The LP5862 integrates 18 constant current sinks for driving 18 yellow LEDs. With the help of two additional LP5862 drivers, it is possible to realize, as shown on this board, a solution of 54 yellow LEDs arranged in a circular pattern. In addition, it also provides excellent PWM dimming effects.
