SPI interface for STM32L476VG

[RShiv.1]

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,

SPI init is succeeding whereas INT i s failing what could be the issue??..hardware NFC05A1...then how do we proceed from here??,,kindly help us on this.

Hi,

is the Gnd properly connected on the scope probe?

Can you confirm that you have press the B1 reset push button on the STM32L476VG-DISCO  while probing?

is the CN8.1 pin high or low?

Have you properly connected ST25R3911B VDD_IO and VDD power supply?

Hi BT,

1.Yes, the GND is connected properly on the scope probe.

2.Yes we have pressed the B1 reset push button on the STM32L476VG-DISCO.

3.CN8.1 pin is low

4.Yes we are seeing the green light in ST25R3911B  board..we are seeing SPI init passed as mentioned earlier.

Hi BT,

we are also getting MOSI and MISO line ...

Hi BT,

any pointers for us??

Hi BT,

voltage L200 is 3.27 V ....voltage at C203 is also 3.27 V...Kindly let us know if these are ok..

thanks and regards

Hi

Can you check whether R200 is properly soldered on the X-NUCLEO-NFC05A1? can you probe INTR_11 on the board while resetting the MCU?
