Hi Ulysses,
I'm sorry but I'm working on a company project and i am not allowed to provide project code or .hex file.
Anyway, I can provide you the SPI initialization as well as the steps performed for the ST25R3911B initialization and smart card activation.
SPI CONFIGURATION
static void MX_SPI1_Init(void)
{
/* SPI1 parameter configuration*/
hspi1.Instance = SPI1;
hspi1.Init.Mode = SPI_MODE_MASTER;
hspi1.Init.Direction = SPI_DIRECTION_2LINES;
hspi1.Init.DataSize = SPI_DATASIZE_8BIT;
hspi1.Init.CLKPolarity = SPI_POLARITY_LOW;
hspi1.Init.CLKPhase = SPI_PHASE_2EDGE;
hspi1.Init.NSS = SPI_NSS_SOFT;
hspi1.Init.BaudRatePrescaler = SPI_BAUDRATEPRESCALER_16;
hspi1.Init.FirstBit = SPI_FIRSTBIT_MSB;
hspi1.Init.TIMode = SPI_TIMODE_DISABLE;
hspi1.Init.CRCCalculation = SPI_CRCCALCULATION_DISABLE;
hspi1.Init.CRCPolynomial = 7;
if (HAL_SPI_Init(&hspi1) != HAL_OK)
{
Error_Handler();
}
}
After SPI initialization I make the following call to initialize the rfal and to perform antenna calibration:
- rfalAnalogConfigInitialize()
- rfalInitialize()
- rfalCalibrate();
When a ISO 14443 A smart card is put in the field, first I perform the anticollision and then i call the proper rfal routine for the activation sequence as follows:
rfalIsoDepPollAHandleActivation(ISO14443A_RTAS_FSDI_256, RFAL_ISODEP_NO_DID, RFAL_BR_848, &isoDepDev);
Once activated, I try to send an APDU to the card in the following way:
iso14443TransmitAndReceive(&APDU, sizeof(APDU), &rxBuff, sizeof(rxBuff), &actrxlength, isoDepDev.FWT);
At this point RFAL returns ERR_FRAMING.
Reguards, Pierluigi
