Field Documentation

BaudRate

uint32_t SMARTCARD_InitTypeDef::BaudRate

This member configures the SmartCard communication baud rate. The baud rate is computed using the following formula:

• IntegerDivider = ((PCLKx) / (16 * (hsc->Init.BaudRate)))
• FractionalDivider = ((IntegerDivider - ((uint32_t) IntegerDivider)) * 16) + 0.5

WordLength

uint32_t SMARTCARD_InitTypeDef::WordLength

Specifies the number of data bits transmitted or received in a frame. This parameter can be a value of SMARTCARD Word Length

Definition at line 53 of file stm32f4xx_hal_smartcard.h.

Referenced by SMARTCARD_SetConfig().

StopBits

uint32_t SMARTCARD_InitTypeDef::StopBits

Specifies the number of stop bits transmitted. This parameter can be a value of SMARTCARD Number of Stop Bits

Referenced by SMARTCARD_SetConfig().

Parity

uint32_t SMARTCARD_InitTypeDef::Parity

Specifies the parity mode. This parameter can be a value of SMARTCARD Parity

Note

When parity is enabled, the computed parity is inserted at the MSB position of the transmitted data (9th bit when the word length is set to 9 data bits; 8th bit when the word length is set to 8 data bits).

Mode

uint32_t SMARTCARD_InitTypeDef::Mode

Specifies whether the Receive or Transmit mode is enabled or disabled. This parameter can be a value of SMARTCARD Mode

CLKPolarity

uint32_t SMARTCARD_InitTypeDef::CLKPolarity

Specifies the steady state of the serial clock. This parameter can be a value of SMARTCARD Clock Polarity

CLKPhase

uint32_t SMARTCARD_InitTypeDef::CLKPhase

Specifies the clock transition on which the bit capture is made. This parameter can be a value of SMARTCARD Clock Phase

CLKLastBit

uint32_t SMARTCARD_InitTypeDef::CLKLastBit

Specifies whether the clock pulse corresponding to the last transmitted data bit (MSB) has to be output on the SCLK pin in synchronous mode. This parameter can be a value of SMARTCARD Last Bit

Prescaler

uint32_t SMARTCARD_InitTypeDef::Prescaler

Specifies the SmartCard Prescaler value used for dividing the system clock to provide the smartcard clock. The value given in the register (5 significant bits) is multiplied by 2 to give the division factor of the source clock frequency. This parameter can be a value of SMARTCARD Prescaler

NACKState

uint32_t SMARTCARD_InitTypeDef::NACKState

Specifies the SmartCard NACK Transmission state. This parameter can be a value of SMARTCARD NACK State
