uart_setup()

设定指定的UART端口

Description

void uart_setup(int $uart_id, int $baud [, string $ctrl = “N81N”])

Parameters

$uart_id:要设定的UART账号
$baud: 通信速度(单位: bps)
$ctrl: 设定4字节。按顺序parity, data bits, stop bit和flowcontrol。基本值为“N81N”。 (“N81N”: No parity(N), 8 data bits, 1 stop bit, No-flowcontrol(N).)

Return Value

none

Example

<?php
include "/lib/sd_340.php";
uart_setup(0, 9600, "E71N"); // set UART0 to 9600 bps, Even parity, 7 data bits, 1 stop bit, No-flowcontrol
uart_setup(1, 115200);       // set UART1 to 115200bps
?>
