Qi RX Click

Qi RX Click is a compact add-on board made for the purpose of wireless power transfer. This board features the PIC16F15313, a general-purpose 8-bit MCU that makes a flexible, low-cost alternative to the wireless charging solutions based on ASICs from Microchip.

Click library

• Author : Stefan Ilic
• Date : Oct 2021.
• Type : I2C type

Software Support

We provide a library for the QiRX 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 QiRX Click driver.

Standard key functions :

• qirx_cfg_setup Config Object Initialization function.

  void qirx_cfg_setup ( qirx_cfg_t *cfg );

• qirx_init Initialization function.

  err_t qirx_init ( qirx_t *ctx, qirx_cfg_t *cfg );

Example key functions :

• qirx_read_data Read data function.

  uint16_t qirx_read_data ( qirx_t *ctx );

• qirx_read_voltage Read voltage function.

  uint16_t qirx_read_voltage ( qirx_t *ctx, uint16_t v_ref );

Example Description

This is an example that demonstrates the use of the Qi RX Click board.

The demo application is composed of two sections :

Application Init

Initalizes I2C driver and makes an initial log.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    qirx_cfg_t qirx_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.
    qirx_cfg_setup( &qirx_cfg );
    QIRX_MAP_MIKROBUS( qirx_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == qirx_init( &qirx, &qirx_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    log_printf( &logger, "----------------------- \r\n" );
    log_printf( &logger, "      Qi RX Click       \r\n" );
    log_printf( &logger, "----------------------- \r\n" );

    log_info( &logger, " Application Task " );
    log_printf( &logger, "----------------------- \r\n" );
}

Application Task

This example shows the capabilities of the Qi RX Click by measuring voltage of the connected battery. In order to get correct calculations user should change "v_ref" value to his own power supply voltage.

void application_task ( void ) 
{
    voltage = qirx_read_voltage( &qirx, v_ref );
    log_printf( &logger, " Battery voltage: %d mV \r\n", voltage );
    log_printf( &logger, "----------------------- \r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

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.QiRX

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.
