ATA6570 click

ATA6570 click is a CAN Partial Networking interface board. The click carries the ATA6570, a high-speed CAN transceiver that interfaces a Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus.

Click library

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

Software Support

We provide a library for the Ata6570 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 Ata6570 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void ata6570_cfg_setup ( ata6570_cfg_t *cfg );

  • Initialization function.

    ATA6570_RETVAL ata6570_init ( ata6570_t *ctx, ata6570_cfg_t *cfg );

Example key functions :

  • Write Register

    void ata6570_write_reg ( ata6570_t *ctx, const uint8_t address, uint8_t input );

  • Read Register

    uint8_t ata6570_read_reg ( ata6570_t *ctx, const uint8_t address );

Examples Description

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

The demo application is composed of two sections :

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;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
ATA6570_MAP_MIKROBUS( cfg, MIKROBUS_1 );
ata6570_init( &ata6570, &cfg );
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
}

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.Ata6570

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.
