Library Description
Library provides functions for communication via UART module, and a function for controlling cs pin, which sets device mode.
Key functions:
void canfd4_write_byte ( uint8_t input )
- Writes single byte of datauint8_t canfd4_read_byte( )
- Reads single byte of datauint8_t canfd4_byte_ready ( )
- Checks if new data ic receivedExamples description
The application is composed of three sections :
void application_task ( )
{
char tmp;
uint8_t drdy_flag;
if ( app_mode == APP_MODE_RECEIVER )
{
// RECEIVER - UART polling
drdy_flag = canfd4_byte_ready( );
if ( 1 == drdy_flag )
{
tmp = canfd4_read_byte( );
mikrobus_logWrite( &tmp, _LOG_BYTE );
}
}
else
{
// TRANSMITER - TX each 2 sec
for ( tmp = 0; tmp < 9; tmp++ )
{
canfd4_write_byte( demo_message_data[ tmp ] );
mikrobus_logWrite( ">> MESSAGE SENT <<", _LOG_LINE );
}
Delay_ms(2000);
}
}

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.
