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.
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.
This library contains API for ATA6571 Click driver.
ata6571_cfg_setup
Config Object Initialization function.
void ata6571_cfg_setup ( ata6571_cfg_t *cfg );
ata6571_init
Initialization function.
err_t ata6571_init ( ata6571_t *ctx, ata6571_cfg_t *cfg );
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 );
This example reads and processes data from ATA6571 Clicks.
The demo application is composed of two sections :
Initializes the driver and sets the device operating mode.
void application_init ( void )
{
log_cfg_t log_cfg; /**< Logger config object. */
ata6571_cfg_t ata6571_cfg; /**< Click config object. */
/**
* 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_printf( &logger, "---- RECEIVER MODE ----\r\n" );
#endif
#ifdef DEMO_APP_TRANSMITTER

#endif

app_buf_len = 0;
app_buf_cnt = 0;
log_info( &logger, " Application Task " );
Delay_ms ( 100 );
}
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
ata6571_generic_write( &ata6571, TEXT_TO_SEND, strlen( TEXT_TO_SEND ) );
log_printf( &logger, "---- The message has been sent ----\r\n" );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
#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.

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.
