Click library

  • Author : Stefan Filipovic
  • Date : Nov 2023.
  • Type : GPIO type

Software Support

We provide a library for the OOK RX Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for OOK RX Click driver.

Standard key functions :

  • ookrx_cfg_setup Config Object Initialization function.

    void ookrx_cfg_setup ( ookrx_cfg_t *cfg );
  • ookrx_init Initialization function.

    err_t ookrx_init ( ookrx_t *ctx, ookrx_cfg_t *cfg );

Example key functions :

  • ookrx_enable_device This function enables device by setting the EN pin to high logic state.

    void ookrx_enable_device ( ookrx_t *ctx );
  • ookrx_wait_ready This function waits for all training bytes to arrive which indicates data ready.

    static void ookrx_wait_ready ( ookrx_t *ctx );
  • ookrx_read_packet This function reads data packet and stores it in a packet_buf only if the OOKRX_PREAMBLE bytes are received successfully.

    static uint8_t ookrx_read_packet ( ookrx_t *ctx );

Example Description

This example demonstrates the use of OOK RX Click board by reading and parsing packet messages received from the transmitter.

The demo application is composed of two sections :

Application Init

Initializes the driver and enables the device and squelch mode.


void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    ookrx_cfg_t ookrx_cfg;  /**< Click config object. */

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );

    // Click initialization.
    ookrx_cfg_setup( &ookrx_cfg );
    OOKRX_MAP_MIKROBUS( ookrx_cfg, MIKROBUS_1 );
    if ( DIGITAL_OUT_UNSUPPORTED_PIN == ookrx_init( &ookrx, &ookrx_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    ookrx_enable_squelch ( &ookrx );
    ookrx_enable_device ( &ookrx );

    log_info( &logger, " Application Task " );
}

Application Task

Waits for a data ready indication, then reads all packet data, verifies the CRC bytes in a packet, and displays its data as well as the RSSI value on the USB UART.

void application_task ( void )
{
    static float rssi_v = 0;
    static uint8_t packet_len = 0;
    static uint8_t msg_cnt = 0;
    static uint16_t crc = 0;

    log_printf( &logger, "\r\n Waiting for data ready...\r\n" );
    ookrx_wait_ready ( &ookrx );
    packet_len = ookrx_read_packet ( &ookrx );
    if ( packet_len )
    {
        ookrx_read_rssi_voltage ( &ookrx, &rssi_v );
        crc = ( ( uint16_t ) packet_buf[ packet_len - 2 ] << 8 ) | packet_buf[ packet_len - 1 ];
        if ( crc == micrftx2_calculate_crc16 ( packet_buf, packet_len - 2 ) )
        {
            log_printf( &logger, " Received message: " );
            for ( msg_cnt = 0; msg_cnt < packet_buf[ 2 ]; msg_cnt++ )
            {
                log_printf( &logger, "%c", ( uint16_t ) packet_buf[ msg_cnt + 3 ] );
            }
            log_printf( &logger, "\r\n RSSI: %.1f dBm\r\n", OOKRX_RSSI_V_TO_DBM ( rssi_v ) );
        }
    }
    Delay_ms ( 100 );
}

Note

The OOK TX Click board is a compatible transmitter for the OOK RX Click. Here are a few steps for troubleshooting if you are experiencing issues running this example:

  • Check the MCU clock configuration, use an external oscillator instead of the MCU's internal one for better accuracy on manchester data rate delay.
  • Measure the actual data rate on the data line and adjust the OOKRX_MAN_BIT_LEN_US value accordingly.

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.OOKRX

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. UART terminal is available in all MikroElektronika compilers.
