Library Description

The library covers all the necessary functions to control iqRF 2 Click board.

Key functions:

  • void iqrf2_writeByte(uint8_t input) - Write Single Byte.
  • uint8_t iqrf2_readByte() - Read Single Byte.
  • uint8_t iqrf2_byteReady() - Check for new byte received.

Examples description

The application is composed of the three sections :

  • System Initialization - Initializes UART and LOG structures and start to write log.
  • Application Initialization - Initialization driver enables - UART, also write log.
  • Application Task - This is an example which demonstrates the use of iqRF 2 click board. Checks if new data byte has received in RX buffer ( ready for reading ), and if ready than reads one byte from RX buffer. In the second case, the application task writes message data via UART. Results are being sent to the Usart Terminal where you can track their changes
void applicationTask()
{
    char tmp;
    uint8_t rdyFlag;

// RECEIVER - UART polling

    rdyFlag = iqrf2_byteReady();

    if (1 == rdyFlag)
    {
        tmp = iqrf2_readByte();
        mikrobus_logWrite( &tmp, _LOG_BYTE );
    }

// TRANSMITER - TX each 2 sec
/*
    for (tmp = 0; tmp < 9; tmp++)
    {
        iqrf2_writeByte( MESSAGE_DATA[tmp] );
        Delay_ms( 100 );   
    }

    Delay_ms( 2000 );
*/
}

Other mikroE Libraries used in the example:

  • UART

Additional notes and informations

Depending on the development board you are using, you may need USB UART clickUSB 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.

Headphone AMP Click

0

Headphone Amp Click is a compact add-on board that contains a stereo headphone amplifier. This board features the LM4811, Boomer® audio power amplifier capable of delivering 105mW per channel with digital volume control from Texas Instruments. The Boomer® amplifiers are specifically designed to provide high-quality output power with a minimal amount of external components. Since the LM4811 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems. It features a digital volume control that sets the amplifier's gain from +12dB to −33dB in 16 discrete steps, in addition to a micro-power consumption Shutdown mode.
