MICRF TX Click is a compact add-on board designed as a powerful RF transmitter for data transmission over the 315MHz frequency band. This board features the MICRF112, a high-performance RF transmitter IC from Microchip, renowned for its efficiency in operation. This Click board™ stands out for its ease of use, requiring only a simple crystal oscillator to set the frequency, and supports both ASK and FSK modulation types with a Phase-Locked Loop (PLL) for stable frequency.

Click library

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

Software Support

We provide a library for the MICRF TX 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 MICRF TX Click driver.

Standard key functions :

  • micrftx_cfg_setup Config Object Initialization function.

    void micrftx_cfg_setup ( micrftx_cfg_t *cfg );
  • micrftx_init Initialization function.

    err_t micrftx_init ( micrftx_t *ctx, micrftx_cfg_t *cfg );

Example key functions :

  • micrftx_send_data This function builds and sends a packet of data. The packet format is as follows (MSB first, manchester IEEE 802.3): MICRFTX_TRAINING_BYTES, PREABMLE, LEN, DATA_IN, CRC16 (calculated from whole packet excluding training bytes).
    static void micrftx_send_data ( micrftx_t *ctx, uint16_t preamble, uint8_t *data_in, uint8_t len );

Example Description

This example demonstrates the use of MICRF TX Click board by sending a predefined message to the receiver.

The demo application is composed of two sections :

Application Init

Initialized the driver and logger.


void application_init ( void )
{
    log_cfg_t log_cfg;          /**< Logger config object. */
    micrftx_cfg_t micrftx_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.
    micrftx_cfg_setup( &micrftx_cfg );
    MICRFTX_MAP_MIKROBUS( micrftx_cfg, MIKROBUS_1 );
    if ( DIGITAL_OUT_UNSUPPORTED_PIN == micrftx_init( &micrftx, &micrftx_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

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

Application Task

Sends a predefined message every 3 seconds and displays it on the USB UART.

void application_task ( void )
{
    log_printf ( &logger, " Sending data: %s\r\n\n", ( char * ) MICRFTX_MESSAGE );
    micrftx_send_data ( &micrftx, MICRFTX_PREAMBLE, MICRFTX_MESSAGE, strlen ( MICRFTX_MESSAGE ) );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

Note

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

  • Make sure the MICRF TX Click is set to ASK mode with on-board jumpers.
  • 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 MICRFTX_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.MICRFTX

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.

IR Grid 2 Click is a thermal imaging sensor. It has an array of 768 very sensitive factory calibrated IR elements (pixels), arranged in 32 rows of 24 pixels. Each one of them is measuring an object temperature up to 300˚C within its local Field of View (FOV). The MLX90640ESF-BAB IR sensor used on this Click board™ has just four pins, and it is mounted inside of the industry standard TO39 package. It is equipped with 2Kbit of EEPROM for storing the compensation and calibration parameters.
