软串口问题
我想用蓝牙和433M无线来控制电机的。但是433M能用，能接受到433发出来的，蓝牙就收不到信号进来。刚开始玩得，不知道软串口怎么写。各路大神帮个忙，帮忙写写。代码：#include <RCSwitch.h>
RCSwitch mySwitch = RCSwitch();
int val;
void setup() {
Serial.begin(9600);
mySwitch.enableReceive(0);
}
void loop()
{
if (mySwitch.available()) //下面是433M
{
int value = mySwitch.getReceivedValue();
if (value == 0)
{
Serial.print("Unknown encoding");
}
else
{
Serial.print("Received ");
Serial.print( mySwitch.getReceivedValue() );
Serial.print(" / ");
Serial.print( mySwitch.getReceivedBitlength() );
Serial.print("bit ");
Serial.print("Protocol: ");
Serial.println( mySwitch.getReceivedProtocol() );
//powerRelayState = !powerRelayState; //总继电器状态反转
//digitalWrite(relayState01 , HIGH); //代码错误，已删除，未测试
//relayState01 = !relayState01; //继电器01状态反转
}
mySwitch.resetAvailable();
} //下面是蓝牙
if (Serial.available()) //如果串口有信息传入
{
val = Serial.read(); //赋予val值为读取串口信息
if (val == 'm') //如果传入val值为'm'
{
Serial.println("OK!"); //串口反馈"OK!"
//powerRelayState = !powerRelayState; //总继电器状态反转
//digitalWrite(relayState01 , HIGH); //代码错误，已删除，未测试
//relayState01 = !relayState01; //继电器01状态反转
}
}
}
