ATA6571 click

ATA6571 Click is a compact add-on board that contains a transceiver designed for high-speed CAN applications. This board features the ATA6571, a standalone high-speed CAN FD transceiver that interfaces a CAN protocol controller and the physical two-wire CAN bus from Microchip.

Click library

  • Author : Stefan Filipovic
  • Date : Jun 2021.
  • Type : UART type

Software Support

We provide a library for the ATA6571 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for ATA6571 Click driver.

Standard key functions :

Example key functions :

  • ata6571_set_operating_mode This function sets the device operating mode by controlling the EN and NSTB pins.
    void ata6571_set_operating_mode ( ata6571_t *ctx, uint8_t op_mode );
  • ata6571_generic_write This function writes a desired number of data bytes by using UART serial interface.
    err_t ata6571_generic_write ( ata6571_t *ctx, char *data_buf, uint16_t len );
  • ata6571_generic_read This function reads a desired number of data bytes by using UART serial interface.
    err_t ata6571_generic_read ( ata6571_t *ctx, char *data_buf, uint16_t max_len );

Example Description

This example reads and processes data from ATA6571 clicks.

The demo application is composed of two sections :

Application Init

Initializes the driver and sets the device operating mode.

void application_init ( void )
{
log_cfg_t log_cfg;
ata6571_cfg_t ata6571_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
Delay_ms( 100 );
log_info( &logger, " Application Init " );
// Click initialization.
ata6571_cfg_setup( &ata6571_cfg );
ATA6571_MAP_MIKROBUS( ata6571_cfg, MIKROBUS_1 );
err_t init_flag = ata6571_init( &ata6571, &ata6571_cfg );
if ( UART_ERROR == init_flag )
{
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
Delay_ms( 100 );
#ifdef DEMO_APP_RECEIVER
log_printf( &logger, "---- RECEIVER MODE ----\r\n" );
#endif
#ifdef DEMO_APP_TRANSMITTER
log_printf( &logger, "---- TRANSMITTER MODE ----\r\n" );
#endif
app_buf_len = 0;
app_buf_cnt = 0;
log_info( &logger, " Application Task " );
Delay_ms( 100 );
}

Application Task

Depending on the selected demo application mode, it reads all the received data or sends the desired message every 2 seconds.

void application_task ( void )
{
#ifdef DEMO_APP_RECEIVER
ata6571_process();
if ( app_buf_len > 0 )
{
Delay_ms( 100 );
ata6571_process();
log_printf( &logger, "%s", app_buf );
log_printf( &logger, "-------------------------------------\r\n" );
ata6571_clear_app_buf( );
}
#endif
#ifdef DEMO_APP_TRANSMITTER
log_printf( &logger, "---- The message has been sent ----\r\n" );
Delay_ms( 2000 );
#endif
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.ATA6571

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. UART terminal is available in all MikroElektronika compilers.
