ATA6570 Click

ATA6570 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.

Click Library

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

Software Support

Example Description

This application is interfaces a Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Ata6570

Example Key Functions

  • ata6570_cfg_setup Config Object Initialization function.
void ata6570_cfg_setup ( ata6570_cfg_t *cfg );
  • ata6570_init Initialization function.
err_t ata6570_init ( ata6570_t *ctx, ata6570_cfg_t *cfg );
  • ata6570_write_reg Write Register.
void ata6570_write_reg( ata6570_t *ctx, const uint8_t address, uint8_t input );
  • ata6570_read_reg Read Register.
uint8_t ata6570_read_reg( ata6570_t *ctx, const uint8_t address );

Application Init

In addition to this module is palced inside normal working mode cappable of tranmission and reception of data.

void application_init ( void )
{
    log_cfg_t log_cfg;
    ata6570_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.

    ata6570_cfg_setup( &cfg );
    ATA6570_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    ata6570_init( &ata6570, &cfg );
    ata6570_write_reg( &ata6570, ATA6570_DMCR, ATA6570_OPMODE_NORMAL );
    Delay_ms ( 500 );
}

Application Task

Tranismiter/Receiver task depend on uncommented code Receiver logging each received byte to the UART for data logging, while transmiter send message each 2 seconds.

void application_task ( void )
{
     //  Task implementation.
    
#ifdef DEMO_APP_RECEIVER
       // RECEIVER - UART polling
      rsp_size = ata6570_generic_read( &ata6570, uart_rx_buffer, PROCESS_RX_BUFFER_SIZE );

      if ( rsp_size > 0 )
        {  
            log_printf( &logger, "%s", uart_rx_buffer );
            memset( uart_rx_buffer, 0, rsp_size );
        }  
#endif
       
#ifdef DEMO_APP_TRANSMITER
       // TRANSMITER - TX each 2 sec
       for( uint8_t i = 0; i < 8; i++ )
       {
           ata6570_generic_write( &ata6570, &demo_message[ i ], 1 );
       }
       Delay_ms ( 1000 );
       Delay_ms ( 1000 );
#endif
}

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.
