int livox_ros::UserUart::Open

(

const char *

filename

)

set baudrate and parity,etc.

Definition at line 53 of file user_uart.cpp.

int livox_ros::UserUart::Setup	(	uint8_t	baudrate_index,
		uint8_t	parity
	)

sets up the port parameters

clear old setting completely,must add here for CDC serial

Enable the receiver and set local mode...

Disable hardware flow

Disable software flow

set boadrate

No parity (8N1)

Even parity (7E1)

Odd parity (7O1)

Space parity is setup the same as no parity (7S1)

now we setup the values in port's termios

Enable non-canonical

Time to wait for data

Minimum number of characters to read

flush the port

send new config to the port
