NFC10A1 on NUCLEO -F303

[DIvan.1]

Hello,

I would like to develop a system using the NFC chip ST25R200 and the microcontroller STM32F303. The main idea is to be able to read an NFC tag, specifically the ST25DV64KC.

As a first step, I plan to test this using the prototyping board NUCLEO-F303 and the NFC expansion board X-NUCLEO-NFC10A1. I'm using CubeIDE.

I'm sure that ST has prepared everything for a simple and smooth integration. Because of that, I'm confused about what I'm doing wrong.

After configuring the pins and integrating the middleware/software in STM32CubeMX, I get errors when I try to compile the code (I haven't changed anything in the generated code).

Here is picture with Pins defined:

here is Middleware/software package included and set:

  

SPI1, Interrupt, GPIO configure:

 

After generating code I go to main.c where I want to compile generated code and get a lot of errors:

Can you please help me understand what I'm doing wrong?
In the past, I worked with the ST25R3912, so I have some experience.
If you need more information, feel free to ask.

Hi,

make sure to select an RFAL configuration. It seems not selected in your case:

This should be something like:

See attached ioc file as an example.

That solved my problem.

Thank you very much.

If I want to use NFC-V and allowed energy harvesting for tag (ST25DV64KC)...

1. what is the minimum of the functions I need to use?

2. what of these options I need to use:

I'm a bit sceptical with time spending using all that functions.

Thank you and best regards,

Hi,

in a perfect world, you should choose Custom_config for the RFAL and then select RFAL_FEATURE_NFCV and RFAL_FEATURE_ST25xV and regenerate. In that case the project also defines RFAL_ANALOG_CONFIG_CUSTOM whereas no custom analog config are provided, so #define RFAL_ANALOG_CONFIG_CUSTOM needs to be manually commented in the nfc_conf.h.

Unselected technologies are then not used in the discovery loop and the linker removes the unused part of the code.

Thank you.

So I did the following 4 steps:

Is this enaugh or I need to uncheck some other things? thank you very much

If I do this 4 steps and compile code I get no errors.

Best regards,

Hi,

this should be fine: only NFC-V technology plus support of ST25TV/ST25DV API are selected.

Okey, but with this configuration I don't need to insert #define RFAL_ANALOG_CONFIG_CUSTOM like you said.

If I check RAM, FLASH usage are in both cases the same:

I have a feelings like nothing changes.

Should I uncheck what the bottom red arrow shows or anything else?

thank you and best regards,

Hi,

Sorry for the confusion about RFAL_ANALOG_CONFIG_CUSTOM, I was using a pre-release version of the FW package.

Regarding RAM/FLASH usage

Default:

Custom:

Make sure to use the following compiler settings:

and the following linker setting:

Check the map file for the custom build vs the default build: functions such as rfalNfcaPollerInitialize should be absent in the custom build map file.

Also adjust the compiler optimization level according to your needs.
