ATA6563 Click

ATA6563 click carries the ATA6563 high-speed CAN transceiver. The click is designed to run on a 5V power supply. Use the VIO SEL jumper for selecting the 3.3V or 5V logic level. It communicates with the target microcontroller over UART interface, with additional functionality provided by the AN pin on the mikroBUS™ line.

ATA6563 features

The ATA6563 is a high-speed CAN transceiver that provides an interface between a controller area network (CAN) protocol controller and the physical two-wire CAN bus.

The transceiver is designed for high-speed (up to 5 Mbps) CAN applications in the automotive industry, providing differential transmit and receive capability to (a microcontroller with) a CAN protocol controller. It offers improved electromagnetic compatibility (EMC) and electrostatic discharge (ESD) performance.

The transceiver is CAN FD (Flexible data-rate) ready, meaning it has increased data rates in comparison with classic CAN.

How the click works

ATA6563 click is connected to a CAN bus via the DB9 cable, which then communicates with the network.

Code snippet

A simple example of the ATA6563 library usage. The example waits until 8 bytes are received on the RX and then prints the received data using the other UART module.

01 void main()
02 {
03     int i = 0;
04     system_init();
05     while( 1 ) {
06         if( Button( &GPIOA_IDR , 5, 100, 1 ) ){
07             ata6563_send( TX_DATA, sizeof( TX_DATA ) );
08             TFT_Write_Text( "Data Sent", 50, 100 );
09         }
10         if( ( chk = ata6563_rdy() ) == 8 ){
11             ata6563_read( buf, chk );
12             for( i = 0; i < chk; i++ )
13                  UART1_Write( buf[ i ] );
14         }
15     }
16 }
