Library Description

Library carries generic functions which are enough to have complete control over MiWi click.

Key functions

void miwi2_writeReg(uint8_t address, uint8_t value)- Writes data to the register

uint8_t miwi2_readReg(uint8_t address)- Reads data from the register

void miwi2_writeFIFO(uint8_t Data)- Writes data to the FIFO buffer

uint8_t miwi2_readFIFO()- Reads data from the FIFO buffer

Examples Description

Demo application is modified version of Microchip's application for MRF89XA devices. Application is in the form of a console app with simple UI which allows operations such as register_read or write but also TX and RX routines.

This function (code snippet) continuously transmits predefined packet with delay of 100 ms between each transaction.

void RadioApp_txPredefinedPacket()
{
    uint8_t input;
    uint8_t tmpPacket[ 6 ] = { 80, 65, 67, 75, 69, 84 };

    ConsolePut_constString("Transmitting predefined packet at");
    RadioApp_printMiniStatus(PR_TX_MODE);
    ConsolePut_constString("Press (Ctrl+z) to exit");
    ConsolePut_newLine();

    while (1)
    {
        if (ConsoleGet_ready())
        {
            input = ConsoleGet();
            ConsolePut(input);

            if (input == 26)
            return;
        }

        miwi2_sendPacket(&tmpPacket[0], 6);
        _miwi2_rfMode = _MIWI2_RF_STANDBY;
        Delay_ms( 100 );
    }
}

Other 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.
