Click library

• Author : MikroE Team
• Date : feb 2020.
• Type : UART type

Software Support

We provide a library for the Ata663211 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 Ata663211 Click driver.

Standard key functions :

• ata663211_cfg_setup Config Object Initialization function.

  void ata663211_cfg_setup ( ata663211_cfg_t *cfg );

• ata663211_init Initialization function.

  err_t ata663211_init ( ata663211_t *ctx, ata663211_cfg_t *cfg );

Example key functions :

• ata663211_generic_write Generic write function.

  err_t ata663211_generic_write ( ata663211_t *ctx, uint8_t *data_buf, uint16_t len );

• ata663211_generic_read Generic read function.

  err_t ata663211_generic_read ( ata663211_t *ctx, uint8_t *data_buf, uint16_t len );

Examples Description

This example demonstrates the use of an ATA663211 click board by showing the communication between the two click boards.

The demo application is composed of two sections :

Application Init

Initalizes device and makes an initial log.

void application_init ( void )
{
    log_cfg_t log_cfg;
    ata663211_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.
    ata663211_cfg_setup( &cfg );
    ATA663211_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    ata663211_init( &ata663211, &cfg );
#ifdef DEMO_APP_TRANSMITTER
    log_printf( &logger, " Application Mode: Transmitter\r\n" );
#else
    log_printf( &logger, " Application Mode: Receiver\r\n" );
#endif
}

Application Task

Depending on the selected application mode, it reads all the received data or sends the desired text message with the message counter once per second.

void application_task ( void )
{
#ifdef DEMO_APP_TRANSMITTER
    ata663211_generic_write( &ata663211, DEMO_TEXT_MESSAGE, strlen( DEMO_TEXT_MESSAGE ) );
    log_printf( &logger, "%s", ( char * ) DEMO_TEXT_MESSAGE );
    Delay_ms ( 1000 ); 
#else
    uint8_t rx_byte = 0;
    if ( 1 == ata663211_generic_read( &ata663211, &rx_byte, 1 ) )
    {
       log_printf( &logger, "%c", rx_byte );
    }
#endif
}  

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.Ata663211

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.
