Library Description

This library carries generic functions for registers writing and generic functions for communication through CAN bus.

Key functions

void ata6570_writeReg( const uint8_t address, uint8_t input ) - Writes register

uint8_t ata6570_readReg( const uint8_t address ) - Reas register

void ata6570_writeByte(uint8_t input) - Sends single byte through CAN bus

uint8_t ata6570_readByte() - Reads byte received from CAN bus

uint8_t ata6570_byteReady() - Checks if new data has been received

Examples Description

The application is composed of three sections :

• System Initialization - Initializes RST, CS, PWM pin as OUTPUT and INT, AN pin as INPUT and UART module
• Application Initialization - Driver initialization
• Application Task - (code snippet) - Checks if new data byte has been received in RX buffer (ready for reading), and if ready than reads one byte from the RX buffer. In second case application task writes message data via UART.

void applicationTask()
{
// RECEIVER
#ifdef __RX__
    if (ata6570_byteReady())
    {
        tmp = ata6570_readByte();
        mikrobus_logWrite( &tmp, _LOG_BYTE );
    }
#endif

// TRANSMITER
#ifdef __TX__
    uint8_t cnt;
    for (cnt = 0; cnt < 9; cnt++)
    {
        ata6570_writeByte( MESSAGE_DATA[cnt] );
    }
    Delay_ms(2000);
#endif
}

MikroElektronika Libraries used in the example:

• SPI
• UART

Additional notes and information

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.
