程序频繁出现bug！急！明天就要用！
本帖最后由 白羊羊罐头AS 于 2018-6-22 01:38 编辑我在测试一个程序的时候，经常出现一个问题：串口发送打开继电器的数据之后，继电器先是打开，然后串口有好一阵子没传回数据；再发送关闭的数据后继电器就不动了，串口也有好一阵子没反应。这是代码：
#include <SoftI2CMaster.h>
#include <LiquidCrystal_SoftI2C.h>
#include <dht11.h>
volatile int alarm;
LiquidCrystal_SoftI2C mylcd(0x3F,16,2,A5,A4);
dht11 myDHT_2;
int dht_2_gettemperature() {
int chk = myDHT_2.read(2);
int value = myDHT_2.temperature;
return value;
}
int dht_2_gethumidity() {
int chk = myDHT_2.read(2);
int value = myDHT_2.humidity;
return value;
}
void setup(){
Serial.begin(38400);
alarm = 0;
pinMode(4, INPUT);
pinMode(5, OUTPUT);
pinMode(6, OUTPUT);
digitalWrite(6,HIGH);
pinMode(7, OUTPUT);
digitalWrite(7,HIGH);
pinMode(8, OUTPUT);
digitalWrite(8,HIGH);
pinMode(9, OUTPUT);
digitalWrite(9,HIGH);
pinMode(10, OUTPUT);
digitalWrite(10,HIGH);
pinMode(11, OUTPUT);
digitalWrite(11,HIGH);
pinMode(12, OUTPUT);
digitalWrite(12,HIGH);
pinMode(13, OUTPUT);
digitalWrite(13,HIGH);
mylcd.init();
mylcd.backlight();
}
void loop(){
Serial.println(String("Temperature:") + String(dht_2_gettemperature()));
Serial.println(String("Humidity:") + String(dht_2_gethumidity()));
Serial.println(String("Alarm:") + String(alarm));
if (digitalRead(4) == 1 && analogRead(A0) >= 450) {
alarm = 1;
}
if (alarm == 1) {
digitalWrite(5,HIGH);
} else {
digitalWrite(5,LOW);
}
if (Serial.available() > 0) {
if (Serial.readString() == "OpenSwitch1") {
digitalWrite(6,LOW);
}
if (Serial.readString() == "OpenSwitch2") {
digitalWrite(7,LOW);
}
if (Serial.readString() == "OpenSwitch3") {
digitalWrite(8,LOW);
}
if (Serial.readString() == "OpenSwitch4") {
digitalWrite(9,LOW);
}
if (Serial.readString() == "OpenSwitch5") {
digitalWrite(10,LOW);
}
if (Serial.readString() == "OpenSwitch6") {
digitalWrite(11,LOW);
}
if (Serial.readString() == "OpenSwitch7") {
digitalWrite(12,LOW);
}
if (Serial.readString() == "OpenSwitch8") {
digitalWrite(13,LOW);
}
if (Serial.readString() == "CloseSwitch1") {
digitalWrite(6,HIGH);
}
if (Serial.readString() == "CloseSwitch2") {
digitalWrite(7,HIGH);
}
if (Serial.readString() == "CloseSwitch3") {
digitalWrite(8,HIGH);
}
if (Serial.readString() == "CloseSwitch4") {
digitalWrite(9,HIGH);
}
if (Serial.readString() == "CloseSwitch5") {
digitalWrite(10,HIGH);
}
if (Serial.readString() == "CloseSwitch6") {
digitalWrite(11,HIGH);
}
if (Serial.readString() == "CloseSwitch7") {
digitalWrite(12,HIGH);
}
if (Serial.readString() == "CloseSwitch8") {
digitalWrite(13,HIGH);
}
if (Serial.readString() == "AlarmReset") {
alarm = 0;
}
}
mylcd.setCursor(0, 0);
mylcd.print("SmartHome");
mylcd.setCursor(0, 1);
mylcd.print(String(dht_2_gettemperature()) + String("C ")+String(dht_2_gethumidity())+String("%"));
}
这个是整个代码（智能家居），明天就要用！
而且报警部分也无法正常运行！
使用的库：
自己改了一下，已经能用了
