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 :

Example key functions :

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;
qirx_cfg_t qirx_cfg;
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 )
{
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.
