Member Data Documentation

◆ BaudRate

uint32_t IRDA_InitTypeDef::BaudRate

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

IntegerDivider = ((PCLKx) / (8 * (hirda->Init.BaudRate)))
FractionalDivider = ((IntegerDivider - ((uint32_t) IntegerDivider)) * 8) + 0.5

This member configures the IRDA communication baud rate. The baud rate register is computed using the following formula: Baud Rate Register = ((usart_ker_clk) / ((hirda->Init.BaudRate))) where usart_ker_clk is the IRDA input clock

◆ IrDAMode

uint32_t IRDA_InitTypeDef::IrDAMode

Specifies the IrDA mode This parameter can be a value of IRDA Low Power

Definition at line 71 of file stm32f4xx_hal_irda.h.

◆ Mode

uint32_t IRDA_InitTypeDef::Mode

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

Definition at line 63 of file stm32f4xx_hal_irda.h.

◆ Parity

uint32_t IRDA_InitTypeDef::Parity

Specifies the parity mode. This parameter can be a value of IRDA 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).

Definition at line 56 of file stm32f4xx_hal_irda.h.

◆ PowerMode

uint16_t IRDA_InitTypeDef::PowerMode

Specifies the IRDA power mode. This parameter can be a value of IRDA Low Power

Definition at line 71 of file stm32f7xx_hal_irda.h.

◆ Prescaler

uint8_t IRDA_InitTypeDef::Prescaler

Specifies the Prescaler value to be programmed in the IrDA low-power Baud Register, for defining pulse width on which burst acceptance/rejection will be decided. This value is used as divisor of system clock to achieve required pulse width.

Specifies the Prescaler value for dividing the UART/USART source clock to achieve low-power frequency.

Note: Prescaler value 0 is forbidden

Definition at line 66 of file stm32f4xx_hal_irda.h.

◆ WordLength

uint32_t IRDA_InitTypeDef::WordLength

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

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