@par Description

This directory contains a set of source files that implement a simple 
"www.st.com/st25" example based on M24LR URI NDEF message compliant with
the NFC Forum Type 5 tag version 1.0.

@note Care must be taken when using HAL_Delay(), this function provides accurate delay (in milliseconds)
      based on variable incremented in SysTick ISR. This implies that if HAL_Delay() is called from
      a peripheral ISR process, then the SysTick interrupt must have higher priority (numerically lower)
      than the peripheral interrupt. Otherwise the caller ISR process will be blocked.
      To change the SysTick interrupt priority you have to use HAL_NVIC_SetPriority() function.

@note The application need to ensure that the SysTick time base is always set to 1 millisecond
      to have correct HAL operation.

@par Hardware and Software environment  

  - This example runs on STM32L053R8 and STM32F401RE devices.
    
  - This application has been tested with STMicroelectronics:
    STM32L0xx-Nucleo RevC
    STM32F4xx-Nucleo RevC
    boards and can be easily tailored to any other supported device 
    and development board.

  - STM32LXxx-Nucleo and STM32FXxx-Nucleo RevC Set-up    
    - Connect the Nucleo board to your PC with a USB cable type A to mini-B 
      to ST-LINK connector (CN1).
    - Please ensure that the ST-LINK connector CN2 jumpers are fitted.

        
    
@par How to use it ? 

In order to make the program work, you must do the following :
 - Open your preferred toolchain 
 - Rebuild all files and load your image into target memory
 - Run the application
