The options are specified by SERIAL_vInitEx(). This structure does not need to be statically allocated memory.
In principle, these options are not supported. When using them, please check the output signals with an oscilloscope or similar. The following communication settings are supported as standard.
The structure must be cleared to 0 before use.
| bool_t | bHwFlowEnabled | TRUE: Hardware flow enabled FALSE: Disabled |
|---|---|---|
| bool_t | bParityEnabled | TRUE: Parity enabled FALSE: Disabled |
| uint8 | u8ParityType | E_AHI_UART_EVEN_PARITY: even E_AHI_UART_ODD_PARITY: odd (no need to set value if parity is disabled) |
| uint8 | u8StopBit | E_AHI_UART_1_STOP_BIT: 1bit, E_AHI_UART_2_STOP_BIT: 1.5/2bit |
| uint8 | u8WordLen | 7: 7bit, 8: 8bit |
