Hi, I have a question I try to read sensor value and print this value with serial1. But I cant read with serial3 when read this value with serial monitor also I can read initial sensor value but this value doesnt change on serial3. How can I solve this problem(ignore error message)
// serial3 read code
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
Serial3.begin(9600);
}
String totalstring;
char lastchar;
String hiz;
void loop() {
// put your main code here, to run repeatedly:
while(lastchar != '\n')
{
if(Serial3.available())
{
lastchar=Serial3.read();
totalstring=totalstring+lastchar;
//Serial.println(lastchar);
}
//Serial.println(lastchar);
}
lastchar=' ';
hiz=totalstring.substring(totalstring.indexOf("a"),totalstring.indexOf("k"));
// Serial.println(hiz);
Serial.println(totalstring.c_str());
}
//serial1 print code
void setup() {
Serial.begin(9600);
Serial1.begin(9600);
}
void loop() {
int deger;
deger =analogRead(A0);
deger=map(deger, 0, 1023, 0, 255);
Serial1.print("a");
Serial1.print(deger);
Serial1.println("k");
Serial.print("a");
Serial.print(deger);
Serial.println("k");
delay(100);
}
