SPI interface for STM32L476VG

RShiv.1 · ‎2021-03-01

STM32L476VG is the MCU we are interfacing with ST25R3911B using SPI.

what we have understood from some search is that we need RFAL (abstraction layer) to interface with RF HAL.

Then once we integrate RFAL and RF HAL in our system workbench(ac6) project we need to build the integration then use SPI calls to read the register from RFID reader ST25R3911B

we wanted to use ISO-14443A standard to be configured and read the values.

where do we get the basic RFAL work space or code flow so that we shall use in our current project?

Kindly guide us and let us know are we in right path?

Hi BT,

just to add ..we have removed the LCD on the Disco board...

Hi,

it seems you have configured PA3 with an internal pull up... This pull is conflicting with the IRQ....

Please make sure to properly configure PA3 as follow:

Hi,

are you sure you have connected the proper pin on the X-NUCLEO-NFC05A1 side (i.e. CN8 pin 1)? Do you see the interrupt when probing with a scope?

do you see the interrupt falling on MCU side?

Hi BT,

Yes we are sure we have connected to CN8 pin1 ..attaching the pics for your reference..

No interrupt seen when probing in scope..on the MCU side and also on the CN8.
