Field Documentation
◆ enable
| USART_Enable_TypeDef USART_InitAsync_TypeDef::enable |
Specifies whether TX and/or RX is enabled when initialization is completed.
◆ refFreq
| uint32_t USART_InitAsync_TypeDef::refFreq |
USART/UART reference clock assumed when configuring baud rate setup.
Set to 0 to use the currently configured reference clock.
◆ baudrate
| uint32_t USART_InitAsync_TypeDef::baudrate |
Desired baud rate.
◆ oversampling
| USART_OVS_TypeDef USART_InitAsync_TypeDef::oversampling |
Oversampling used.
◆ databits
| USART_Databits_TypeDef USART_InitAsync_TypeDef::databits |
Number of data bits in frame.
Notice that UART modules only support 8 or 9 data bits.
◆ parity
| USART_Parity_TypeDef USART_InitAsync_TypeDef::parity |
Parity mode to use.
◆ stopbits
| USART_Stopbits_TypeDef USART_InitAsync_TypeDef::stopbits |
Number of stop bits to use.
◆ autoCsEnable
| bool USART_InitAsync_TypeDef::autoCsEnable |
Auto CS enabling.
◆ csInv
| bool USART_InitAsync_TypeDef::csInv |
Enable CS invert.
By default, chip select is active low. Set to true to make chip select active high.
