I want to send the ST25R3916B nfc tag readings to CAN bus.

[NAkku.1]

I have program for CAN bus and NFC08a1 but when i combine i get several errors. All i want to do is get the reading from the nfc reader and send them on can. does anyone know how to do that?

Hi,

make sure to keep platformErrorHandle aligned with the error handler function defined in the main.c (i.e. Error_Handler).

The SPI settings are incorrect vs the ST26R3916B Datasheet .:

•  hspi1.Init.DataSize = SPI_DATASIZE_8BIT; <<<<< 8 bits, not 4 bits
•  hspi1.Init.CLKPhase = SPI_PHASE_2EDGE; <<<< a clock polarity of 0, a clock phase of 1, 
• SPI_BAUDRATEPRESCALER_2 looks strange to me. Make sure to not exceed 6Mbps when configuring from STM32CubeMx (likely SPI_BAUDRATEPRESCALER_16 for a system clock `@80MHz)

Hi,

can you add the IRQ_3916B signal and send to me the salae file so that I can analyze it (I can do nothing with a screen shot).

Thanks
