Click library

  • Author : MikroE Team
  • Date : dec 2019.
  • Type : SPI type

Software Support

We provide a library for the ExcelonLP 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 ExcelonLP Click driver.

Standard key functions :

  • Config Object Initialization function.

    void excelonlp_cfg_setup ( excelonlp_cfg_t *cfg );

  • Initialization function.

    EXCELONLP_RETVAL excelonlp_init ( excelonlp_t ctx, excelonlp_cfg_t cfg );

Example key functions :

  • Functions for send opcode command

    void excelonlp_send_command ( excelonlp_t *ctx, uint8_t opcode );

  • Functions for read data

    void excelonlp_read_data ( excelonlp_t ctx, uint8_t opcode, uint8_t out_buf, uint8_t n_data);

  • Functions for write data to memory

    void excelonlp_write_memory_data ( excelonlp_t *ctx, uint8_t opcode, uint32_t addr, uint8_t c_data);

Examples Description

This application writes in RAM memory and read from RAM memory.

The demo application is composed of two sections :

Application Init

Initializes Device init


void application_init ( void )
{
    log_cfg_t log_cfg;
    excelonlp_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.

    excelonlp_cfg_setup( &cfg );
    EXCELONLP_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    excelonlp_init( &excelonlp, &cfg );
}

Application Task

Reads device ID, writes 6-bytes (MikroE) to memory and reads 6-bytes from memory


void application_task ( )
{
    uint8_t out_buf[ 20 ] = { 0 };
    uint8_t cnt;
    char memory_data[ 3 ];
    uint8_t send_buffer[ 7 ] = { 'M', 'i', 'k', 'r', 'o', 'E', 0 };
    uint32_t memory_address = 0x00000055;

    log_printf( &logger, "Read Device ID: " );
    excelonlp_send_command( &excelonlp, EXCELONLP_OPCODE_SET_WRITE_ENABLE_LATCH );
    excelonlp_read_data( &excelonlp, EXCELONLP_OPCODE_READ_DEVICE_ID, &out_buf[ 0 ], 9 );
    for( cnt = 0; cnt < 9; cnt++ )
    {
        log_printf( &logger, " 0x", out_buf );
        Delay_100ms();
    }
    log_printf( &logger, "\r\n" );

   log_printf( &logger, "Write MikroE data." );
   excelonlp_send_command( &excelonlp, EXCELONLP_OPCODE_SET_WRITE_ENABLE_LATCH );
   for ( cnt = 0; cnt < 6; cnt++ )
   {
        excelonlp_send_command( &excelonlp, EXCELONLP_OPCODE_SET_WRITE_ENABLE_LATCH );
        excelonlp_write_memory_data( &excelonlp, EXCELONLP_OPCODE_WRITE_MEMORY_DATA, memory_address++, send_buffer[ cnt ] );
        Delay_100ms();
   }
   memory_address = 0x00000055;
   log_printf( &logger, "Read memory data: " );
   for ( cnt = 0; cnt < 6; cnt++ )
   {
       memory_data[ 0 ] = excelonlp_read_memory_data( &excelonlp, EXCELONLP_OPCODE_READ_MEMORY_DATA, memory_address++ );
       log_printf( &logger, " %d", memory_address );
       Delay_100ms();
   }
   Delay_ms ( 1000 );
   Delay_ms ( 1000 );
   Delay_ms ( 1000 );
   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.ExcelonLP

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.
