X-CUBE-NFC6 example code

[RAvkh]

Hello!

In X-CUBE-NFC6 manual https://www.st.com/content/ccc/resource/technical/document/user_manual/group1/16/85/63/86/35/64/42/47/DM00635198/files/DM00635198.pdf/jcr:content/translations/en.DM00635198.pdf

i can see:

"2.1 Overview

The X-CUBE-NFC6 software package expands the STM32Cube functionality.

The package key features are:

• Sample application to detect NFC tags of different types and mobile phones supporting P2P, card emulation mode and read/write"

But in package i can't find this example. I can find only "WriteURI" example.

Where i can get "Sample application to detect NFC tags"?

Hi,

the package should have all that in e.g.

STM32CubeExpansion_NFC6_V1.0.0\Projects\STM32L476RG-Nucleo\Applications\PollingTagDetect\Src\demo.c, ndef_demo.c

Project e.g. in STM32CubeExpansion_NFC6_V1.0.0\Projects\STM32L476RG-Nucleo\Applications\PollingTagDetect\MDK-ARM

I'm successfully implement my own EMV-kernel (Visa+Mastercard) using this example as a starting point. All works fine, thank you.

Now i need to change PINs, used for SPI communication with ST25R3916 (to upload program to my custom board):

NSS - PB0

IRQ - PC5

To do this, i made changes in spi.h:

#define BUS_SPI1_NSS_GPIO_PIN     GPIO_PIN_0

#define BUS_SPI1_IRQ_GPIO_PIN     GPIO_PIN_5

#define BUS_SPI1_IRQ_GPIO_PORT     GPIOC

#define BUS_SPI1_IRQ_GPIO_CLK_ENABLE() __HAL_RCC_GPIOC_CLK_ENABLE()

But example stops working after this changes. Sometimes i can read ChipID register (0x2A), but nothing else.

I've made experiments on X-NUCLEO-NFC06A1 board.

What else i need to change in code to correctly change pins, used for spi communication?

Hi,

please provide logic analyzer traces of the issue to be able to inspect.
